Install the new element (one of the most common Moffat oven replacement parts).
-
Reconnect wires and secure the panel.
Step 2: Fix or Replace Thermostat or Sensor
-
Access the sensor inside the oven cavity or behind the control panel.
-
Use a multimeter to test resistance (check your model’s specs for correct values).
-
If readings are off, remove and replace with a matching part.
-
Calibrate temperature settings after replacement.
Step 3: Clean or Replace Fan Motor
-
Take off the rear panel and check for oil accumulation on the fan.
-
Clean the motor casing and blades.
-
If the fan won’t turn or makes noise, replace the fan motor.
