my accuwave microwave oven wont heat things up. tray turns, it counts down like it should, and when i try to use any of the automatic sensor functions it stops and displays -F3H- . also the fan no longer works.
ANSWER Hello Al,
The F3H error code indicates a humidity sensor failure. To test you will need a good sensor and control board. You will unplug unit and connect sensor to P5 on the control board. Plug unit back up. If the error code does not come up then install the sensor. If error code returns then replace control board.
