I Put The New Tray In the Microwave

Not done yet. Expecting a lot of difficulty. Model is for counter top only; building contractor installed it over the range, under the cabinets.

My grandfather who is well versed as an electrician checked my microwave out because it wasn't worked. He used a multimeter to check electric current to parts in the microwave. He said a specific thermostat was not getting any current going through. I ordered that replacement part from this site and when it came in it didn't have current running through it either. He said he thought the part that was given to me was faulty. I called this companies number to ask some questions but the machine said they aren't taking any inquiry calls because of the pandemic right now. So I currently don't know what the problem is with my microwave. I want to return the part but unfortunately during Christmas time the packaging got thrown away. So as of right now I'm out the part money and probably money to buy a new appliance.

The new thermostats also did not have continuity between it's terminals.. so I ordered a second one.. it also did not pass for continuity.. before returning both I installed one and it worked.. so am not sure why continuity is the recommended test to find the original problem..

The diagnosis is about an hour. Coz, I need to open the control panel, got a tester, and trsted all critical parts inside the panel.
Also, replaced the fuse just to make sure its a new one. Found out it was a switch (bottom part) that control the open/close of the microwave door.

When found out the problem, the rest of the work is easy.

Unfortunately for us, it wasn't the diode that needed to be replaced. The instructions that were given on how to discharge the capacitor before working on the diode, magnatron or capacitor itself, was very helpful. You don't need to be and electrician if you can follow directions. Ours ended up being the magnatron. It took about 15 minutes to swirch out. I had to buy yhe part thru another site, because it was $40. 00 Dollars cheaper and the part was here in one day. Thanks for the information on the repair.

Replaced the diode next to the capacitor. If you replace a capacitor, replace the diode while your in there so you don't have to disassemble and reassemble twice.
