Oven and range repair guides covering uneven heating, gas igniter diagnosis, error codes, and safety checks for all major brands.
Oven problems show up when the stakes are highest — Thanksgiving turkey, a dinner party, or a weeknight meal when nothing else will do. Uneven heating, a gas burner that clicks but never lights, a self-clean cycle that locks the door permanently, or an error code that kills power to the entire unit: these are the scenarios our guides walk you through step by step, from initial diagnosis through the repair decision.
Gas and electric ovens fail differently and we separate the guides accordingly. Gas oven igniter replacement is the single most common oven repair in our service records — the silicon carbide igniter draws current through a safety valve, and when its resistance rises above the threshold, the valve never opens even though the igniter glows. Electric ovens more often suffer bake or broil element burnout, temperature sensor drift that causes 25-50 degree swings, and control board relay failures on models with electronic controls.
For dual-fuel ranges and commercial-style units (Viking, Wolf, Thermador), we include the specific calibration procedures and error code tables that differ from their residential counterparts. These high-end units require specialized service and our guides tell you exactly which repairs are safe for a homeowner and which demand a certified technician.

GE oven F-codes group into four families — sensor faults (F1/F3/F4), over-temp (F2), board faults (F0/F5/F8), and input/lock (F7/F9). Read the family, then repair. EasyBear guide.

A GE oven shutting off on its own is often the 12-hour auto-off, not a fault. Rule it out, then check the sensor, thermal fuse, relay, or power. EasyBear guide.

GE oven barely heating when you bake? On a gas model it's usually a weak bake igniter; on electric, an open bake element. Here's how to tell which and what to check.

GE oven smoking when you turn it on? It's usually food residue, self-clean burn-off, or a new-oven cure — but persistent smoke can mean a failing element. Here's how to tell.

A GE oven igniter that glows orange but never lights the gas is almost always too weak to draw the amps that open the safety valve. Here is the amp test and the part numbers.

A noisy GE oven is usually one of its cooling or convection fans — but some sounds are perfectly normal. Match the noise to its source before you spend a dime.

A dead GE oven display is usually a control-board power-supply fault, an aged VFD screen, or a loose ribbon cable. Here are the causes ranked by likelihood, how to confirm partial power first, and which GE parts each points to.

A GE oven leaking heat from the door sides or bottom is usually a hardened door gasket that no longer seals, or weak hinge springs letting the door sag at the top. Here's how to find the gap.

A GE oven that overheats is usually a temperature sensor reading low so the board overheats it, or a welded element relay stuck on. An F2 code means it hit the over-temp cutout — turn it off at the breaker.

A GE electric oven that trips its big 240V breaker almost always has a bake or broil element shorted to ground — a fault that pulls hundreds of amps and trips instantly. Burned wiring and the terminal block come next.

A GE oven making a loud noise is most often worn convection fan bearings (grinding), then delayed gas ignition (a boom), a buzzing control-board relay, or loose panels. How to tell normal oven sounds from abnormal ones and diagnose each.

A GE oven that smells like gas is usually a weak igniter dragging out preheat, but a leaking safety valve, a loose gas connection, dirty burner ports, or a blocked vent can all cause it. How to tell a normal preheat whiff from a dangerous leak, plus the causes ranked.

Most likely: a drifted RTD temperature sensor or a stale calibration offset, which together account for the majority of "runs hot" and "runs cold" complaints. Keep some perspective first — a 25°F swing around the set point is normal cycling for any home oven, and only variations of 50°F or more…

Most likely the self-clean lock has not released. A GE oven stays locked until the cavity cools below about 550°F, so wait a full hour and power-cycle the breaker. If it is still locked, the lock motor has usually stripped its gears from the heat, or the board is stuck in self-clean. An F97 or F7 code helps. Never force the handle.

Most likely: the door latch will not lock, and GE's control refuses to start a self-clean it cannot seal — often with an F5 code. A temperature sensor out of range, an already-blown thermal fuse, or an oven still too hot to begin are the other usual reasons…

A GE oven that vibrates during a convection bake is most often an imbalanced convection fan or worn fan-motor bearings, but an unlevel range, loose panels, or cabinet contact can add to it. The five causes ranked, with models like the PT9200 and CT9070.

GE oven door stuck locked or locking by itself? The latch motor, door-position switch, and ERC board faults ranked, plus the safe self-clean cool-down rule.

GE oven baking unevenly with hot spots or raw centers? On convection models it’s usually the convection fan; otherwise a drifted sensor, a partly failed element, or a worn door gasket. Ranked fixes.

GE oven element won’t glow? Half the time it’s a burned-out element; the rest is a board relay, burned wiring, or a tripped thermal fuse. How to inspect and meter-test a GE bake or broil element.

GE gas burner clicks but won’t light? Usually a wet or dirty spark electrode, a misaligned cap, or clogged gas ports — rarely the spark module. Ranked causes, cleaning steps, and gas-safety notes.

Rust in a GE oven usually starts where the porcelain enamel has chipped, exposing steel to moisture. Here is where it develops, the ranked causes, and when rust means replacement.

GE oven quits mid-bake or mid-self-clean? Sensor drift, a blown thermal fuse, ERC board, element, or weak gas igniter — ranked, with the F-code table that pins the fault fast.

GE oven latch won’t lock for self-clean, or won’t unlock after? Motor, position switch, ERC lock relay, obstruction, or wiring — ranked, plus the safe way to free a door stuck locked.

GE oven door sagging, glass cracked, or not sealing? Diagnose worn hinges, cracked inner glass, a hardened gasket, a broken handle, or shattered outer glass — with the hinge-lock removal trick.

Gaggenau oven running hot, cold, or off by a wide margin? It's usually the temperature sensor drifting or a calibration offset. Here's how to diagnose and correct it.

A Gaggenau steam oven that won't produce steam is most often lime scale clogging the boiler — run the descaling program first — or a failed boiler heater, often shown as E14 or E15.

Most likely: a pyrolytic self-clean lock that failed to release, especially if power blipped mid-cycle and the lock stayed engaged after the oven cooled. Because Gaggenau is part of the BSH Group, its lock assemblies are shared with Bosch and Thermador, so the failure modes track those platforms —…

A Frigidaire oven that won't turn off is a fire risk — cut the breaker now. The cause is a welded board relay, a shorted temperature sensor, or a stuck touchpad. EasyBear guide.

Frigidaire oven door stuck shut, usually after self-clean? It's the thermal door lock. Learn how to release it safely and what to do if the latch motor has failed.

Most likely: grease residue carbonizing on the exposed bake element — spilled food bakes onto the element and smokes every time it heats up, by far the most common cause. On a brand-new oven, harmless smoke during the first two or three uses is just the factory protective coating burning off. The…
