      Dawn GarrisonAug 8, 2025
      If the fuse blows when the door is closed and the START key is touched, it could be due to a malfunction in the high voltage transformer, the high voltage capacitor (including the diode), the magnetron, the blower motor, or the circuit board. Check for microwave energy leakage according to INTERLOCK ADJUSTMENT PROCEDURES on page 7-12 when the primary interlock, secondary interlock switches and/or the interlock monitor switches are adjusted or replaced.

      If the fuse blows immediately after closing the door on your Sears Microwave Oven, it indicates improper operation of the primary interlock, secondary interlock switches, and/or the interlock monitor switch. If the fuse is blown by an improper switch operation, replace all switches and the fuse at the same time.
