How to Fix Error F5

DIY Fix Perform basic reset

  1. Unplug the microwave from the power outlet.
  2. Wait at least 10–15 minutes to allow any residual charge to dissipate.
  3. Plug the microwave back in and attempt a short cooking cycle to see if the error clears.

Technician Only Inspect and replace main control board or relays

  1. Disconnect power and remove the outer cabinet to access the control board.
  2. Visually inspect the main control board for burnt relay contacts or damaged components.
  3. Test or replace the power relay and, if necessary, replace the entire control board with a manufacturer‑specified part.
  4. Verify other high‑voltage load components (magnetron, transformer) are not shorted to prevent re‑stress of new relay.
  5. Reassemble and test the microwave’s operation.

Parts needed: Main control board (PCB), Power relay on control board
