How to Fix Error Code F44

  1. Disconnect power and inspect door alignment

    Always unplug the microwave before performing any repairs. Microwaves contain high-voltage capacitors that can remain charged even when unplugged.
  2. Clean door seals and contact points

  3. Test door latch mechanism

  4. Remove outer cover to access door switches

    Ensure power is disconnected. Be extremely careful around the high-voltage capacitor and transformer. Do not touch any internal components with bare hands.
  5. Inspect door switch wiring and connections

  6. Test door switches with multimeter

    Only test switches with power disconnected. Handle the multimeter probes carefully to avoid short circuits.
  7. Replace faulty door switches

  8. Reassemble and test operation

    If the error persists after door switch replacement, there may be a control board issue requiring professional service.
