Get a Panasonic unit. They are the most efficient and under $100.

If it's totally dead, the main fuse may have blown. However, since it was inconsistent before it went dead, it might lead me to think that you have a loose connection. Sometimes they heat, lose continuity, and then work again when they cool. A defective thermal protector might also cause this.

It is time to replace the microwave oven, if the fuse is open you more than likely have a more serious problem that will be costly, companies only go back a few years when it comes to supply parts

check power between power cord connection and inernal fuse,start at cord connection and work way to fuse conn.eliminating possibe problem area

2 simple things to check: Inside there is a fuse (15 A) check it. Check that the TCOs (thermal cut outs) are closed ie zero resistance across them.

I have the same problem, plug is fine...Did you get yours to work??

yes it s a large ceramic fuse and you have to remove the outer cover to access this. it will be on the top of the M/wave frame either front L or front right. Cost is about $40.00

It may be a fuse or, the power supply board. you can check the fuse by removing the cover. the (IN-LINE) fuse is located on the power supply board. check it for continuity. if the fuse is in good condition, replace the power board.

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to

open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
