GE Microwave Error Codes: PF, Sensor Error, F-Codes Complete Guide

Quick Answer

GE microwaves use descriptive text errors rather than alphanumeric codes on most models. 'PF' (Power Failure) is the most common GE microwave error - it simply means power was interrupted and the clock needs resetting.

GE microwaves use descriptive text errors rather than alphanumeric codes on most models. 'PF' (Power Failure) is the most common GE microwave error - it simply means power was interrupted and the clock needs resetting. This is NOT a fault. 'Sensor Error' or 'Sensor Cooking Error' means the humidity sensor detected abnormal readings during a sensor cook cycle - usually because the food was not appropriate for sensor cooking or the sensor is dirty. 'Insert Food' or 'Food Error' appears when the sensor does not detect food moisture in the cavity. 'F' followed by a number (F3, F4) on older GE models indicates a hardware fault. GE microwaves do not have a user-accessible diagnostic mode - professional service is needed for persistent F-codes.

About These Ge Microwave Error Codes

GE microwave errors: PF = power failure (not a fault, just reset clock), Sensor Error = humidity sensor issue during sensor cook, Food Error = no food detected by sensor.

Most Common Error Codes

Power interruption (PF)40%
Sensor dirty or food not suitable for sensor cook24%
No food in cavity for sensor cycle14%
Control board fault (F-codes)12%
Keypad membrane moisture10%

Symptoms You May Notice

  • PF flashing on display
  • Sensor Error during cooking
  • Food Error on display
  • F3 or F4 on older models
  • Clock reset to 0:00
  • Microwave beeping with error

How to Identify Your Error Code

1

For PF

For PF: press the Clear/Off button. Reset the clock. PF simply means the power was interrupted - this is NOT a fault code. If PF appears without a known outage, check the electrical connection and outlet.

2

For Sensor Error

3

For F-codes (F3, F4) on older GE models

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Is PF on my GE microwave an error?
No. PF stands for Power Failure and simply indicates the power was interrupted. Press Clear/Off and reset the clock. This happens after power outages, breaker trips, or if the microwave is plugged into a loose outlet. It is not a fault code.
Why does my GE microwave keep saying Sensor Error?
The humidity sensor needs a clean interior to work properly. Food splatter on the ceiling or walls of the microwave cavity interferes with humidity readings. Clean the interior thoroughly. Also ensure you are using sensor cook with appropriate foods - sensor cooking does not work well with very dry foods or empty containers.
GE microwave F3 or F4 - repair or replace?
F3 and F4 on older GE models indicate a hardware fault (temperature sensor or keypad). If the microwave is over 5 years old, replacement is usually more economical. A new GE over-the-range microwave costs $200-400 installed, while board repair is $150-250.
