Most common repairs needed to fix a Frigidaire oven
Thermostat Replacement
A thermostat in the control section of the oven trips to turn on the cooling fan when temperature in that area gets warm. The thermostat should reset to turn the fan off when temperature in the control area cools down below the thermostat reset temperature. If the control cooling fan stays on constantly, the thermostat may be stuck in the tripped position. When the cooling fan in your Frigidaire oven won’t turn off, schedule oven repair service and we’ll send a Sears Home Services technician to your home to fix the problem.
PCB Replacement
In some Frigidaire ovens, the cooling fan in the control area is controlled by the PCB (also called the electronic control board). The control board senses temperature in the control area through a signal sent by the thermistor. If the PCB isn’t detecting the thermistor signal properly or the relay sending electrical current to the cooling fan is stuck, the fan will run constantly. When the cooling fan in your Frigidaire oven runs constantly and never shuts off, schedule oven repair service to have a technician visit your home and fix the problem.
Thermistor Replacement
A thermistor is a temperature sensor that detects temperature through changes in its resistance. The PCB or electronic control board sends a low-voltage DC signal through the thermistor and determines temperature by checking the voltage drop through the thermistor. When the thermistor is defective, its resistance will indicate that temperature in the control area is too high even if the actual temperature is a room temperature level. This will cause the electronic control to run the cooling fan constantly. When the cooling fan in your Frigidaire oven runs constantly, have a service technician visit your home and fix the problem.

Sears Home Services recommendations for a Frigidaire oven fan that won’t turn off

What to look out for with a Frigidaire oven fan not turning off diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your oven problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
