Sharp Microwave Error Code EE1

EE1Sharp Microwave

What this code means

Magnetron (1) failure - upper magnetron oscillation problem detected by high voltage monitoring circuit.

First step from the service manual

Test magnetron (1) and blower fan motor using Test Procedures A-J.

Next steps: diagnose the root cause

1
Verify the error code is active

Power cycle the unit and see if the code returns. If it does, the fault is persistent and requires diagnosis.
