Gas & Dual Fuel Range Troubleshooting: 14 Common Problems (and How to Fix Them)

A burner that clicks but won't light. An oven that won't heat even though the light comes on. A flame that's orange instead of blue. If your range is acting up, the good news is that most range problems have simple, fixable causes—a misaligned burner cap, a little moisture, a tripped breaker, or a setting that's slightly off.

This guide walks through the most common gas and dual fuel range issues, what causes them, and exactly how to fix them safely. It's written from the manufacturer's side of the bench, using the same diagnostic logic our support team and the Proline owner's manual rely on. Wherever a problem crosses the line from a quick DIY fix into "call a pro" territory, we'll tell you plainly.

Before you start: Always let burners, grates, and the oven cool completely before touching them, and unplug the range (or switch off its breaker) before any cleaning or maintenance that involves the igniter, bulb, or internal components.

First, a Word on Gas Safety

Range troubleshooting is usually low-stakes—but gas safety is the exception, so read this before anything else.

If you smell gas:

• Do not try to light any appliance.
• Do not touch electrical switches, and don't use a phone inside the building.
• Leave the building immediately and call your gas supplier from a safe location. If you can't reach them, call the fire department.

Beyond that, two rules cover almost everything: never check for gas leaks with an open flame (use a soapy-water solution and watch for bubbles instead), and all gas line work, gas conversions, and air-shutter adjustments should be performed by a qualified, licensed technician. Several fixes below stop at the point where a tool or a pro is required—that boundary is there for a reason.

Know Your Range: Gas vs. Dual Fuel

A lot of "my oven won't heat" confusion comes down to not knowing which engine is under the hood. Proline's freestanding ranges come in two configurations, and the model number tells you which one you have:

• Gas models (GG) — PLSR 30GG, 36GG, 48GG. Gas-powered cooktop and a gas-powered oven. These plug into a standard 120V outlet; the electricity only runs the ignition, controls, and lights, not the heat.
• Dual fuel models (GE) — PLSR 30GE, 36GE, 48GE. Gas-powered cooktop with an electric oven. These require a dedicated 240V connection because the electric oven needs it to heat.

That difference matters for diagnosis: a gas oven that won't heat is almost always an ignition or gas-supply issue, while a dual-fuel electric oven that won't heat is almost always an electrical, element, or control issue. (If you're still deciding between the two, our guide on gas vs. dual fuel ranges breaks down the trade-offs.)

One more thing worth knowing: every Proline range uses electronic ignition with auto re-ignition, so the burners are designed to relight themselves automatically if a flame is ever disrupted. Keep that in mind below—a little clicking is normal; constant clicking is not.

Cooktop and Burner Problems

1. A Burner Won't Light and There's No Clicking

When there's no clicking sound at all, the igniter isn't getting what it needs—which usually points to power or gas supply rather than the burner itself.

What to check:

1. Power. The cooktop's igniters run on electricity even on gas models. Make sure the range is plugged into its grounded outlet (not an extension cord or adapter), the outlet isn't controlled by a wall switch, and the circuit breaker hasn't tripped.
2. Gas supply. Confirm the gas shutoff valve serving the range is fully open. If your range was recently moved, a partially closed valve or kinked connector is a common culprit.
3. Recent installation or LP conversion. If the range is new or was just converted to liquid propane, the work should have been completed and pressure-tested by a qualified technician before use.

If power and gas are both confirmed and the burners still don't click, the igniter or spark module may need service.

2. The Burner Clicks But Won't Light

This is the single most common cooktop complaint, and it's usually one of three easy fixes. (It also tends to show up right after you've cleaned the cooktop—which is a big clue.)

1. Dry out the burner. Moisture on or around the igniter—from a spill or a recent wipe-down—will stop the gas from lighting. Remove the burner cap and let everything air-dry completely before trying again. In humid kitchens, running your range hood for a minute first helps draw moisture away.
2. Re-seat the burner cap. If a cap was knocked out of position or replaced incorrectly after cleaning, it can block the spark from reaching the gas. With the cooktop cool, lift the cap and re-center it squarely on the burner base so it sits flat.
3. Clean the burner ports. Food debris and grease can clog the small ports around the burner head. Clean them gently with a soft brush or a toothpick. Do not enlarge the holes—and skip wooden toothpicks that can snap off inside a port.

If the spark looks weak (a faint yellow or orange spark rather than a crisp blue-white one) and the burner still won't light after cleaning and drying, the igniter is likely wearing out and should be replaced.

3. The Igniter Keeps Clicking Even After the Burner Lights

On a healthy burner, the clicking should stop the instant the flame catches. Constant clicking after ignition almost always traces back to two things:

• A misaligned or wet burner cap—re-center the cap once the cooktop is cool, and make sure it's fully dry. This resolves the large majority of cases.
• A downdraft or "air-curtain" style hood blowing across the cooktop. This is a subtle one: a downward-blowing vent can push the flame away from the igniter, which then keeps sparking to re-ignite it. Proline's manual specifically advises against pairing the range with downdraft air-curtain hoods for exactly this reason. If you have one, lowering the blower speed or raising the burner's flame setting usually stops the clicking. (A properly sized overhead range hood avoids the problem entirely.)

4. The Flame Is Yellow or Orange Instead of Blue

A correctly adjusted flame is blue, steady, and quiet. A flame that burns mostly yellow or orange signals incomplete combustion, which is worth addressing promptly—both because it cooks poorly and because incomplete combustion can produce carbon monoxide.

What causes it, and what to do:

1. Dirty or clogged burner ports are the most frequent cause. Clean the ports and the burner cap thoroughly (see fix #2) and let everything dry.
2. Drafts from a nearby window, fan, or vent can distort the flame. Eliminate the draft and see if the flame settles.
3. An incorrect air-to-gas mixture—the air shutter may need adjustment. This is not a DIY fix; it must be done by a qualified technician.
4. An incomplete or incorrect LP conversion. A natural-gas range that's been moved to propane (or vice versa) without the correct orifices and regulator setting will burn improperly. Verify the conversion was completed correctly by a pro.

A small amount of yellow tipping on the flame is normal when running on liquid propane. A flame that's mostly yellow or orange is not—clean the burner first, and if it persists, call for service.

5. The Flame Is Weak, Low, or Uneven

If a burner lights but the flame is feeble or lopsided:

1. Clean the burner components. Residue on the cap or base, or clogged ports, will choke and distort the flame. This fixes most cases.
2. Check for restricted gas flow. Look for a kinked or pinched flexible connector behind the range—common after the unit has been pushed into place.
3. Confirm the cap is seated and dry after any cleaning.

If the flame stays weak across the whole cooktop, the issue may be gas pressure or the pressure regulator, which a technician should evaluate.

6. One Burner Works, But Another Doesn't

This comparison is genuinely useful for narrowing things down:

• If only one burner misbehaves, the problem is almost always local to that burner—a clogged port, a misaligned or wet cap, or a worn igniter. Work through fixes #2 through #5 for that burner specifically.
• If all burners are weak or won't light, look upstream at the gas supply, gas pressure, the regulator, or (for clicking issues) the shared spark module. Whole-cooktop problems are more likely to need a technician.

7. The Gas Oven Won't Heat or Won't Ignite

On a gas oven (PLSR GG models), heat comes from a gas burner that's lit by an igniter—so a no-heat oven is usually a gas, ignition, or settings issue.

1. Confirm the gas supply is on and the range has power (the igniter needs electricity even though the heat is gas).
2. Double-check the controls are set correctly to Bake (or Broil) and an appropriate temperature.
3. Listen and look. When you start a Bake cycle, the igniter should glow or spark, followed by the burner lighting and a steady blue flame, with warm air soon rising from the oven vent at the rear of the cooktop. If the igniter never glows or clicks, it likely needs to be replaced by a qualified technician.

8. The Broiler Won't Light

A broiler that won't fire is often a simple setup issue rather than a fault:

1. Close the oven door fully. The broiler is meant to run with the door shut on these models.
2. Verify the rack position matches your recipe—usually an upper position for broiling.
3. Confirm the control is set to Broil (labeled Grill on dual fuel models—same function, different name).

If the burner still won't ignite with the door closed and the control set correctly, the igniter or burner needs service.

Oven Problems - Dual Fuel Models (GE, Electric Oven)

9. The Electric Oven Won't Heat (But the Light and Fan Work)

This is the classic dual-fuel scenario: the cooktop works, the oven light comes on, the fan runs—but no heat. Because the electric oven depends on a full 240V supply, the diagnosis is electrical.

1. Reset the power. Switch off the range's circuit breaker (or unplug it) for about three minutes, then restore power and try a Bake cycle. This clears a surprising number of control glitches.
2. Verify the 240V supply. A dual fuel oven needs a properly grounded 240V connection. If it's only receiving 120V—for example, if one leg of the circuit has failed—the elements won't heat even though the lights and controls (which run on lower voltage) work normally. This is a common root cause of the "everything works except the heat" pattern and should be checked by a qualified electrician or technician.
3. Confirm the breaker hasn't half-tripped. A 240V circuit uses a double breaker; if only one side trips, you get partial power. Fully cycle the breaker off and back on.

If power is confirmed and the oven still won't heat, a bake/broil heating element or the oven control board may have failed and will need professional diagnosis and replacement.

10. The Oven Heats Slowly or Won't Reach Temperature

If a dual-fuel oven heats but tops out below your set temperature (a common report is "won't go past ~350°F"):

1. Allow a full preheat. These ovens typically take about 30-35 minutes to fully preheat, and frequent door-opening resets that clock.
2. Suspect a failing element. A bake element that's partially burned out may still glow but can't reach higher temperatures. A visual inspection often reveals blistering or a break.
3. Consider the control/relay board or temperature sensor if the element looks intact.

Items 2 and 3 involve testing voltages and components and are best left to a technician—but the preheat check in step 1 is free and resolves more cases than you'd expect.

11. The Oven Temperature Seems Inaccurate

Before assuming the oven is "off," rule out the everyday causes:

1. Let it fully preheat. Loading food before the oven reaches temperature is the number-one reason results seem off. Wait for the indicator light to signal it's ready.
2. Check your rack position against the recipe.
3. Stop opening the door. Every peek drops the temperature and extends cooking.
4. Verify with an oven thermometer. Place one in the center, set 350°F, and give it at least 20-30 minutes before reading—the thermometer lags real air temperature, so test patiently. If it's consistently and significantly off, the oven may need calibration; contact support for the procedure on your model.

12. Food Cooks Unevenly

Uneven results are usually about airflow and placement, not a malfunction:

• Center your cookware on the rack and leave space around dishes so heat can circulate.
• Avoid crowding the oven and don't line racks or the oven bottom with foil—it blocks airflow and traps heat.
• Use light-colored bakeware for standard baking; dark pans absorb more heat and over-brown.
• Turn on convection (if your model is equipped) for multi-rack baking, and reduce the recipe temperature by about 25°F when you do.

13. The Broiler or Grill Isn't Browning

If broiling (called Grill on dual fuel models) isn't delivering that quick, direct heat:

• Keep the oven door closed during broiling on these models.
• Move the rack up. Broiling works best with food close to—but not touching—the upper element or burner.
• Preheat the broiler before adding food, and use a broiler-safe pan (no glass cookware in Grill mode).

Controls, Lights, and Power

14. The Control Panel Isn't Responding

1. Check the breaker and confirm the power cord is plugged in securely.
2. Reset the range by disconnecting power for several seconds, then restoring it.
3. If it's still unresponsive after a reset, contact support—there may be an internal electronics fault.

The Oven Light Won't Turn On

Usually just a bulb. With the range unplugged and the oven cool, remove the lens, replace the bulb with a high-temperature appliance bulb (a standard bulb won't survive oven heat), reinstall the lens, and restore power. If a fresh, fully seated bulb still won't light, check that the range has power.

What to Do During a Power Outage

Because ignition is electric, here's the split:

• Cooktop: You can light the surface burners manually. Turn the knob to the ON position and carefully bring a match or lighter to the burner head, then adjust the flame normally.
• Oven: The oven cannot be used during a power outage on either gas or dual fuel models—both rely on electricity to operate. (Curious why a gas oven still needs power? Our explainer on whether a gas oven uses electricity digs into it.)

Odors, Smoke, and Moisture (Usually Completely Normal)

Not every surprise is a problem. These three are expected:

• Smoke or an odor the first few times you bake. That's manufacturing residue burning off. Run the empty oven at about 400°F for 30-45 minutes (with your range hood on and a window cracked) to clear it.
• A smell while broiling. Usually splattered grease or high-fat foods hitting the hot element or burner. Clean the broiler pan, trim excess fat, and make sure the rack is positioned correctly.
• Moisture or steam on the oven door. Normal during cooking; it dissipates as the cycle continues.

Preventing Range Problems: A Little Maintenance Goes a Long Way

Most service calls trace back to buildup and small misalignments—both easy to prevent. A simple routine keeps ignition crisp and flames clean:

Monthly

• Wipe burner grates to remove grease and residue.
• Check that burner caps and bases are clean, dry, and seated correctly.
• Inspect the igniter electrodes and clean off any buildup.

Every 3-6 Months

• Clean the oven interior to clear baked-on residue (avoid getting cleaner on the gasket, vent, or burner openings).
• Inspect the oven door gasket for wear or looseness—a damaged seal causes heat loss and uneven cooking.
• Confirm burners ignite smoothly and the range is still level and stable.

As Needed (By a Qualified Technician)

• Inspect the gas connection, flexible connector, and pressure regulator if you ever suspect a leak or notice a performance change.

A few habits matter too: use flat, stable, appropriately sized cookware; never line the oven bottom with foil; let cast-iron grates cool before washing (and dry them fully to prevent rust); and avoid harsh oven cleaners, steel wool, or abrasive pads on the cooktop, grates, caps, or any stainless surface.

When to Stop and Call a Professional

DIY troubleshooting has a clear stopping point. Shut things down and bring in a qualified technician if:

• You smell gas at any point.
• Burners won't ignite even after cleaning, drying, and re-seating the caps.
• The flame is excessively large, unstable, or mostly yellow after cleaning.
• The oven repeatedly shuts off or won't hold temperature.
• You see sparks, exposed wiring, a tripping breaker, or damaged components.
• You suspect an incorrect LP conversion, or any gas-line or air-shutter work is needed.
• A part appears broken, warped, or severely damaged.

Internal components, gas connections, and pressure adjustments are not DIY territory—leave them to a pro.

Frequently Asked Questions

Why does my gas burner keep clicking even after it lights?
The most common reason is a burner cap that's slightly out of position or still damp from cleaning—re-center it once the cooktop is cool and make sure it's dry. If you use a downdraft or air-curtain hood, it can also blow the flame off the igniter and trigger constant sparking; lower the blower speed or raise the flame setting.

Is an orange or yellow flame on my gas stove dangerous?
A healthy flame should be blue. A mostly orange or yellow flame indicates incomplete combustion, which can release carbon monoxide, so it's worth fixing promptly. Start by cleaning the burner ports and removing any nearby drafts. If it persists, have a technician check the air-to-gas mixture and confirm the LP conversion was done correctly. (A little yellow tipping is normal on propane.)

My gas burner clicks but won't light - what's wrong?
Almost always one of three things: moisture on the igniter, a misaligned burner cap, or clogged burner ports. Dry the burner, re-seat the cap, and gently clean the ports with a soft brush (never enlarge the holes). If the spark looks weak even after that, the igniter may be wearing out.

My dual fuel oven won't heat but the light and fan work - why?
The electric oven needs a full 240V supply. If the lights and controls work but there's no heat, the oven may only be getting 120V (a partially tripped double breaker or a failed leg of the circuit), or a heating element or control board has failed. Cycle the breaker fully off and on first; if that doesn't fix it, have the supply and components checked by a pro.

Can I use my range during a power outage?
You can light the cooktop burners manually with a match or lighter. The oven cannot be used during an outage on either gas or dual fuel models, because ignition and controls require electricity.

How do I clean burner ports without damaging them?
With the cooktop cool, lift off the grate and cap and clear each port with a soft brush or a (non-wooden) pin. Don't enlarge or reshape the holes—that changes the flame and can't be undone. Let everything dry completely before relighting.

Why is my oven cooking unevenly?
Usually rack placement or airflow: center your pans, avoid crowding, skip foil on the racks or oven floor, and use light-colored bakeware. For multiple racks, use convection (if equipped) and drop the temperature about 25°F.

Does a yellow tip on the flame mean something's wrong if I have propane?
No—slight yellow tipping is normal on liquid propane. It's only a concern when the flame is mostly yellow or orange, which points to a cleaning or combustion issue.
