What Does Error F4 Mean?

ge microwave error F4 indicates a problem with the magnetron, which may cause unusual humming sounds or failure to heat food.

Common Causes

  • Magnetron failure (50% likelihood)
  • Cooling fan malfunction (30% likelihood)
  • Faulty high-voltage capacitor (20% likelihood)

Troubleshooting Steps

  1. Step 1: Inspect the cooling fan

    Remove the microwave cover and check if the cooling fan is operational. If it’s not spinning, it may need replacement.

    Ensure the fan is free of dust and debris.

  2. Step 2: Test the magnetron

    Using a multimeter, check the resistance of the magnetron terminals. A reading of infinite resistance indicates a failure.

    Replace the magnetron if it shows no continuity.

  3. Step 3: Check the high-voltage capacitor

    Discharge the capacitor safely and measure its resistance. If it’s outside the normal range, replace it.

    Capacitors can be dangerous; ensure proper discharge before handling.

  4. Step 4: Reassemble and test the microwave

    After replacing any faulty components, reassemble the microwave and test it to ensure the error code is cleared.

    Listen for normal operation sounds during testing.

How to Reset

To reset the F4 error, unplug the microwave for 5 minutes, then plug it back in and check if the error persists.
