GE Microwave F6 Error Code

F6 points to the temperature-probe circuit. If the code returns after one safe reset, use qualified service rather than probing or metering the microwave internally.

Applies to GE microwave oven with an electronic control that uses the documented GE microwave fault-code table

What the appliance detected

Detected condition

GE defines F6 as a shorted temperature probe.

What may contribute

Possible causes

  • The temperature-probe circuit is being reported as shorted.
  • The probe, receptacle, internal wiring, connector, or control may require professional diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the exact display and confirm the model

    • Photograph or write down the complete display before clearing it: F6.
    • Confirm the full GE model number and check the owner documentation for that exact microwave. GE describes this table as a summary of common codes, so model-specific literature takes priority.

  2. Try the GE power reset once, only when conditions are safe

    • If there is no smoke, burning odor, arcing, unusual overheating, visible damage, water intrusion, or repeated breaker trip, shut off the circuit breaker or fuse supplying the microwave for 30 seconds.
    • Restore power once and monitor the display. If the code returns, stop using the microwave and request qualified service rather than repeating resets.

Actions not recommended

  • Do not remove the outer cabinet, control panel, waveguide cover, vent housing, or any microwave service panel.
  • Do not touch or test the high-voltage capacitor, transformer, inverter, magnetron, internal fuses, relays, thermal sensors, humidity sensors, probes, interlock wiring, or control boards. Dangerous voltage can remain after power is disconnected.
  • Do not perform live-voltage, resistance, continuity, capacitor-discharge, or internal connector testing as a homeowner troubleshooting step.
  • Do not bypass, tape, bridge, defeat, or adjust a door-interlock switch, and do not operate a microwave with a damaged or misaligned door.
  • Do not replace a sensor, touch panel, probe, board, relay, fuse, or wiring harness from the display code alone.

When to stop and request service

  • Request qualified microwave service if the code returns after the single GE-documented power reset.
  • Leave the microwave powered off and request service immediately for smoke, a burning odor, repeated arcing, abnormal overheating, a damaged door, visible electrical damage, water near electrical parts, or repeated breaker trips.
