Loud humming/no heating

My GE jvm1440, which we've had for maybe 15 mos. or so, just started making a loud humming noise while running. It doesn't heat, even though everything else appears to be working normally. The humming noise starts a few seconds after the microwave starts. Please help! Thanks.

    I have the exact same problem, worked fine and then started to smell of burning wires and a low hummmmm.

    I had the same problem. The burning smell was an overheating diode caused by a shorted high voltage transformer. I replaced both.

Thank you for the information. I too have had the same problem with my microwave but mine is the model before this one. I am starting to wonder if it is just GE appliances in general that are the problem.

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.

What causes a ge spacemaker above the range microwave to quit heating and makes a deeper pitched noise?

This louder, 60 cycle hum is usually caused by a bad magnetron. The unit will not heat when this happens. Repair cost can exceed $100.

Runs but has loud humming sound. Does not heat. Turntable, timer and lights work.

The diode that connects to the capacitor needs to be replaced. Once its replaced microwave will begin to heat again. (If it wasn't heating and wasn't making a humming noise, then your magnetron would need to be replaced). If you are thinking of doing it yourself and need instructions, i'll be glad to help.

My microwave is making a humming noise but not heating. replaced, capacitor, diode, checked all switches including thermal switches and the wires look good going to the transformer and magnitron. Please...

The part that you did not replace is the problem with the oven, the magnetron. It typically fails and shorts out, causing the oven to make a loud humming noise. Not worth fixing since the cost of the magnetron is typically as much as a new oven. Sorry that you spent your time an money replacing the wrong parts.

The unit is 3 years old and when I turn it on there is a loud hum. Theunit also does not heat but turns the turntable?

From your description it sounds like the magnetron has failed in this oven. That's the part the makes the microwaves to heat the food. It typically fails by shorting out and making a loud hum noise. It not usually worth fixing since the price of a replacement magnetron is almost as much as a new oven.

The microwave oven turns on but does not heat

To allow us to help you effectively (at no charge), please post a NEW problem to FixYa, and please include your brand name and the full model number from the tag in or on the unit, your symptoms, as well as the answers to this question:

- Is there any unusual noise or is it louder or quieter than normal?

We have a sound clip here of what a microwave should sound like when the cooling fan and high voltage section are working.

(A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.)

GE Microwave making loud humming noise

humming sound is your magneto going out Dont have any idea of the cost for replacement however it may be cheaper to purchase another microwave than to repair this one. Good Luck

GE Spacemaker XL1800(JVM1850CF001) - Loud Humming noise

You either have a bad magnetron tube (5 or 10 year parts warranty item through GE Factory Service 1-800-432-2737 or www.geappliances.com) or a shorted high voltage rectifier. I think the light being out is a secondary problem.

Slow turn, hot food

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