I have an Electrolux microwave/wall oven combo. Model # EW27MC65JS1
A couple nights ago while using the microwave it started making an odd fairly loud BUZZING noise and there was a HOT electrical smell. This unit is not under warranty and this is the third problem in roughly 2.5 yrs ( not an Electrolux fan anymore lol). I would appreciate any help on what this issue may be or where I may get started trying to fix it. I have mechanical ability but have never had any dealings with a microwave.

Thanks in advance

Microwaves can be very dangerous for the average person to work on and if you're not experienced especially with that many problems you've had you're better off taking it to an appliance repair place or calling a repairman or replace the unit.
