GE Oven Running Too Hot? Causes & Fix

Most Likely Cause#

A GE oven that runs too hot is usually a temperature sensor reading low or a stuck heating relay. If the sensor reports a temperature cooler than the oven really is, the board keeps the element on and overshoots — set 350°F and the cavity can reach 400 to 425°F. Worse, the element relay on the control board can weld closed from years of arcing, so the element simply never shuts off and the temperature climbs until a safety trips. Sometimes it is milder: the oven just needs a calibration offset, or a broil relay stuck on from preheat leaves both elements running.

An overheating oven is a safety matter, not just a nuisance, so know the warning sign: an F2 code is the board's over-temperature shutdown, telling you the oven exceeded its safe limit.

If the element stays on after you press Cancel, or the oven is clearly overheating, turn it off at the breaker right away — a welded relay that keeps the element energized is a fire risk. Do not throw the door wide open when it is extremely hot; let it cool with the door closed, and note any F2 code before cutting power.

What Usually Causes It#

Sensor and the welded relay#

The sensor (GE part WB21X5301) should read about 1,080 to 1,090 ohms at room temperature; below roughly 1,060 it is reading low and telling the board the oven is cooler than it is, so the element runs too long — also check the sensor lead insulation for a developing short, which drops the reading the same way. The dangerous cause is a welded element relay on the control board: once its contacts fuse, the element stays on no matter what the sensor says, and the temperature climbs until the thermal fuse blows or an F2 over-temp shutdown fires. The test is simple and telling — if the element keeps glowing after you press Cancel and the oven has clearly passed the set temperature, the relay is welded; cut the breaker and do not use the oven.

Calibration, a stuck broil relay, and the gasket#

If the oven is only a steady 15 to 30 degrees hot and passes the sensor test, it likely just needs calibrating: GE lets you set an offset up to about 35 degrees, so on most models hold Bake for a few seconds and dial in a negative offset in small steps against an oven thermometer — that is a normal adjustment, not a repair. On models that use the broil element to speed preheat, a broil relay that sticks on after preheat leaves both elements running during a bake and overheats fast; set a bake, and after it reaches temperature look up — the broil element should not be glowing. Finally, a missing or flattened door gasket makes the oven lose heat and, on GE's aggressive recovery logic, overcompensate into an overshoot, so replace a hardened or missing seal.

Diagnostic Sequence#

1. Verify the actual temperature with an independent oven thermometer.
2. If the element stays on after Cancel and it is overheating, cut the breaker — the relay is welded.
3. Note any F2 code, which is the over-temperature safety shutdown.
4. Measure the sensor at room temperature; well below about 1,080 ohms means it reads low.
5. If it is only slightly hot and the sensor is fine, set a negative calibration offset.
6. During a bake, check that the broil element is not also glowing.

Repair or Replace#

A calibration offset is free and fixes the mild cases. A temperature sensor and a door gasket are inexpensive, easy parts. The control board — behind a welded element or broil relay — is the expensive item, and a welded relay is also the fire-risk case, so on an older oven that is where repair and replacement get weighed. Because overheating can damage the oven and nearby cabinetry, do not keep using it; you can book a visit to have the sensor and control board checked in one trip.
