You probably have a worn out Magnetron Tube... That's the part that generates the Microwave Energy that causes food to cook.. GE has a history of bad Magnetrons so I am not surprised yours failed.. It could also be the transformer for it too.. in either case.. they aren't cheap so you may be better off just buying a replacement microwave... your call.. a magnetron could cost you ~ $250 or so ..Transformer is simlar in price.. depending on the model.. Hope that helps... Also: word of caution.. when dealing with Microwave energy components.. you could get seriously injured if you do the wrong thing and the RF shielding is compromised.. We typically do an RF check after a replacement to make sure the system is safe.. Hope that helps..

It sounds like the main transformer has failed. It would be cheaper to replace the whole microwave than repair this one. Sorry to be the bearer of bad news. Hope this helps. Good luck.

Everything works (clock,lights,turntable) but it does not heat. Is it better to fix or replace?


If everything works and it does not heat, the problem lies with the magnetron circuit. Typically the magnetron fails and the replacement part is almost as much as a new oven. For this model the price of the magnetron is about $80. Unless you really love this oven, your better off replacing it.

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
