What Does Monogram Microwave Error Code F2 Mean?
The F2 error code on a Monogram microwave indicates that the thermal sensor is shorted — the sensor’s resistance reading is near zero, far below the normal operating range. A shorted thermal sensor sends a false “very low temperature” signal to the control board, which may cause the microwave to run heating continuously. The control board detects this and displays F2 as a safety fault.
Common Causes of the F2 Error Code
- Shorted thermal sensor element – The internal resistance element in the thermistor has short-circuited from heat damage, moisture, or component failure.
- Pinched or damaged sensor wiring – Wires that have insulation damaged against the chassis create a short to ground.
- Contamination of sensor connections – Grease or moisture entering the sensor connector can create a conductive path.
How to Troubleshoot the F2 Error Code
- Reset the microwave – Unplug for 60 seconds and retry. If F2 immediately returns, the sensor has definitively failed.
- Confirm the error at startup – Verify that F2 appears at startup, not just during cooking.
When to Call a Professional
The F2 error requires thermal sensor replacement, which involves accessing internal components including dangerous stored electrical charges. This repair should only be performed by a qualified technician. Contact our Monogram microwave repair team at 844-752-7887 for safe and professional repair.
