The Thermostat is an OEM part for LG wall ovens. It is a temperature-sensitive cut-off switch located near the oven's heating elements that monitors interior temperatures and prevents overheating within the appliance. Causes of a bad safety thermostat can be related to prolonged exposure to excessive heat inside the oven cavity, defects in the thermostat's microchip or coil components, or damage from corrosion or physical impact over time. Symptoms of a failed hi-limit thermostat include: The oven's main thermostat clicking repeatedly but no temperature rise inside the cavity Unexpected shutdowns of the oven during heating cycles Smoking or burning smells coming from the oven area Tripped circuit breakers obstructing normal oven operation This OEM LG part is also compatible with some Kenmore models.This part fixes the following symptomsDoesn't shut offEBG51439303 (AP5672246) replaces EBG51439301, 2700856, PS7792254.
