Use a high voltage probe to check high voltage, if present replace the magnatron if no HV replace the high voltage board this is the board that has the heavy wires to the magnatron

My morphy richards p80d20p-yu microwave runs normal but won't heat food


The problem is caused by a bad magnetron, inverter board, "7 years old or less" and possibily the keypad control board.

Ge over range microwave runs but doesnt heat


If it does not heat and makes a loud buzzing sound, it usually means that the magnetron has failed. It the part that generatest the microwaves that heat the food. Replacement costs for magnetrons is almost as much as a new oven, so it rarely makes sense to fix. Sorry.

Crackling and popping sounds when you heat up food


thats normal water expanding and boiling off from the microwave boiling those tiny water pockets in food... sounds like popcorn sometimes.
Cover your food with a paper towel to avoid spatter on the ceiling of the microwave when this is happening.

Have GE JVM2050 over the range microwave, which stopped heating food and water since this morning. All other functions including light, key pad, clock, turntable work normal. The magnetron sound also


if everything works except the heating, it is most likely the mag tube is on its way out.........that is the most common reason for it not too cook.......since the microwave is a GE and it is 3.5 years old, i would say you are better off buying a new microwave, the mag tube starts at around $70.00 and up + the labor it costs too have a service person put it in........around another $60.00

GE JVM1870 Runs, but won't heat up


Our GE jvm1870 is now over 4 yrs old, and had been working fine-- until recently when using, didn't heat anymore & also started making a crazy sound.

Am no electrician, so I called GE to help. Needed a new magnetron & some diode. Part was under a 10 yr warranty- the total cost for service call + labor was under $200. Not great, but beats buying a new microwave ($400-700) and having to install it.
