Fuse blows when door closes after replacing fuse.
My microwave went blank the other day. Replaced the fuse and everything came on, including the inside light even thought the door was closed. Able to set the clock like normal, placing it back in the wall then opening and closing the door, blows the fuse again. This microwave was serviced not too long ago and supposedly all the interlock switched were replaced. Any tips?
yes because I have replaced more than four fuses when its closed runs very well the problem starts when you open the door. burns the fuse sametime
I had same problem - is related to interlock switch wiring. when u close the door that switch completes a safety circuit that engages the transformer and the magnetron. something in that path is shorting the ac hot leg to ground
