The Thermostat is an OEM part for GE ovens. This critical component functions as a temperature sensor and controller within the oven, ensuring that the oven heats to the set temperature and maintains it throughout the cooking process. The thermostat prevents the oven from overheating by cycling the heat on and off as needed.  Symptoms of a failing thermostat include: Oven not reaching the desired temperature Overheating beyond the set temperature Uneven cooking or baking results Oven temperature fluctuating more than usual Causes of thermostat failure generally include age-related wear and tear, calibration issues, or exposure to extreme temperatures that can damage its internal components. This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.WB21X10148 (AP4344046) replaces 1473831, AH2321365, EA2321365, PS2321365, WB20X10020, WB27X10788.
