GE Oven Making a Loud Noise? Causes & Fix
Most likely the convection fan's bearings have worn out, giving a grinding or scraping noise during convection modes — but a delayed-ignition "boom" on gas models, a buzzing control-board relay, or loose panels can each make a new noise, so first tell a normal GE oven sound from an abnormal one.
Normal GE oven sounds#
Not every noise is a fault. These are all normal:
- a gentle whoosh — the convection fan running on Profile and Cafe models during convection bake, Air Fry, or European Convection;
- a single click — the gas igniter sparking at a stovetop burner;
- a soft ping or tick — metal expanding as the oven heats and contracting as it cools;
- a relay click — the board engaging the element relay as it cycles temperature;
- a brief hiss — gas flowing to the oven burner just after the igniter opens the valve.
Abnormal sounds and their causes#
| Sound | Likely cause | Share of cases | First move |
|---|---|---|---|
| Grinding / scraping | Convection fan bearings | 35% | Inspect the convection fan motor |
| Loud boom on ignition | Delayed gas ignition | 25% | Check the oven igniter |
| Loud buzzing / humming | Control-board relay | 15% | Listen at the board, test the relay |
| Rattling / vibrating | Loose panels or covers | 10% | Tighten panels and brackets |

Working through the causes#
Grinding or scraping — convection fan (35%). The convection fan motor (part WB26T10044 on Profile and Cafe models) runs in the heat, and its bearings degrade over time. As they fail the fan grinds, scrapes, or squeals during convection modes — often intermittent and worse on a cold start, then steadily louder. If the noise only appears in convection or Air Fry and rises with use, the fan motor is the cause.
Loud boom on ignition — delayed gas ignition (25%). On gas models, a weak igniter (part WB13K21) opens the safety valve slowly, so gas collects in the burner before it finally lights — and it lights with a startling boom. Beyond the noise, this is worth fixing promptly because the gas build-up is unsafe. A glowing igniter that lights late is the tell; replacing it restores a quiet, prompt light-off.
Loud buzzing or humming — board relay (15%). The oven's control board (the ERC) switches the element through relays, and a failing relay can buzz or hum loudly as its contacts chatter instead of closing cleanly. If a persistent electrical buzz tracks with the element cycling on and off, the board relay is the source and the board is tested for replacement. A relay that chatters like this is also drawing more current than it should, so leaving it is both noisy and hard on the board.
Rattling or vibrating — loose panels (10%). The simplest cause is loose sheet-metal: a back panel, a bracket, or a burner cover that has worked loose vibrates against the cabinet, especially when the convection fan runs. Check and snug the visible panels and brackets before assuming a component has failed. The same rattle can come from a warped rack or a pan resting against the cavity wall, so pull the racks and cookware and run the oven empty to confirm the noise is really coming from the appliance.
When a noise means stop now#
Most oven noises are mechanical and can wait for a scheduled repair, but a few call for shutting the oven off immediately: a loud electrical buzzing paired with a burning smell, any arcing or sparking sound from inside the cavity, or a gas-ignition boom that keeps getting louder. Each of those points to an electrical or gas fault that is unsafe to keep running, so cut power at the breaker — or shut the gas valve — and have it looked at before using the oven again.
Safety First — Know the Risks
Gas ovens involve live gas lines — a loose connection creates explosion and carbon monoxide risk. Electric ovens run on 240V circuits. Our techs are licensed and insured — let them handle the risk.

DIY or call a professional?#
Tightening loose panels is an easy DIY. A convection fan motor or a buzzing ERC board is a moderate job, and anything on the gas side — a delayed-ignition igniter or valve — is best left to a technician, along with any burning smell, sparking, or sign of electrical damage.
Preventing a repeat#
- Wipe up spills promptly so carbonized residue does not smoke or foul components.
- Check oven temperature accuracy every six months and recalibrate if it is off by more than about 25 degrees.
- Inspect the door gasket yearly, since a worn gasket leaks heat and makes the oven work — and cycle — harder.
