Question about GE JVM1440 Microwave Oven

Slow turn, hot food

The GE JVM1440 microwave went from working fine to suddenly running very, very slowly and hardly making any noise. Thought it wasn't heating, but heats to extreme temperature in seconds. Purchased (new) 6 mo. ago.

The problem isn't the turntable. The fan (or lack thereof) is the problem. That's way it is so quiet. There is a general slowdown and all the microwave energy is concentrated in one area. A 1/2 cup of water will boil in 20 seconds.

Buffalo 12980, you are amazing!! Thank you so much. This was not the time to have a sick microwave. Our daughter is getting married Sa. and we have out of town guests. Pretty awesome when the mother of the bride can repair the microwave. Thanks again for your help!!!

Underneath the deck is a geared motor that turns the platter. check for non lubricated bearings or slipping gears.

ok, in the upper part of the cabinet is something that looks like a fan but isn't a fan. its called a chopper and is a metal blade that distributes the microwave energy. microwaves are supplied to the cavity [the oven] through a waveguide [ like a conduit] the chopper breaks up the energy. look for a bound up motor.

The microwave no longer heats food and it smells as if something is burning. Everything else on the microwave works. Is this a common problem and how can I fix it?

Its your Magnatron tube, thats what makes the microwaves and heats the food. The part will cost you more than a new micro. The new model that replaced yours is a JVM1540 and you can get them for 179.00

Food warming time

When you use the microwave does it make abnormal sounds or noises? If so it could be the magnetron going out. Or power setting could have gotten set to its lowest setting

My GE spacemaker microwave doesn't heat up foods. There is a slight bit of heat generated but not much. All timers, lights, etc. work normal. It is a GE model jvm1440. It is about 3 years old. The problem...

IT COULD BE A NUMBER OF THINGS RANGING FROM DIODES TO CAPACITORS TO YOUR MAGNATRON OR THERMOSTAST OR TRANSFORMERS. IT'S DIFFICULT TO DIAGNOSE WITHOUT SEEING THIS MICROWAVE. YOU MAY BE BETTER OFF GETTING YOURSELF A DIFFERENT ONE.

Turntable does not turn and fan won't exhaust

The second problem is probably defective door switches, or it may be a problem with the control panel, which we repair nationwide for only $32.50. On my Web site, I have info on safety, disassembly, and diagnosing and replacing door switches: http://tinyurl.com/yzjozk Running it empty has damaged the magnetron. It will work for a while, but it will eventually have to be replaced. A good parts source is here: http://tinyurl.com/gv383

Loud humming/no heating

Word has it that many of these models have a defect which causes the microwave energy to be reflected back to the magnetron, causing damage to the magnetron, and eventually damaging the high-voltage diode too. Also, the fuse or the magnetron theral cutout / thermostat can eventually blow, too. There is a replacement magnetron and stirrer kit available. I would definitely call the GE Answer Center at 800-626-2005 about this. It's not considered a recall, but a "campaign". They may pick up part of the cost. It's not cheap.
