Question about GE JVM1440 Microwave Oven

Clarification on microwave "cover" access

For milleraba and the similar post on a non-heating microwave, my JVM1440WH01 has same trouble, although everything else seems to work fine on it. I looked at the door latches on mine, and they are plastic. I'm not certain what "cover" I can remove--there's 2 screws securing the vent at top, and screws underneath the unit, but the only access point next to the door latches is a 8-pointed star-like screw (?name) and even if I removed them, the plastic frame would still be in place because I don't see any similar ones on the other side behind the door hinges. Can you clarify what you mean by "cover" and also suggest where I get the volts tested? Thanks.

When putting something in the oven sparks and light appear above from center element.


Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually held in place by a plastic rivet.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart or Lowe's.

If your waveguide cover is burned, it will need to be replaced.

I will need your brand and full model number from the tag in or on the unit to help you further.

Rudy0819: My GE Microwave Spacemaker model JVM1440WH01 just stopped heating. I used it earlier and it worked fine. When I went to use it again, it won't heat. Everthing else works, the light, fan, etc,...


The most likely thing is the magnetron has 'died' but there is a high voltage fuse between the capacitor and the magnetron which may blow. Either way, repairs to microwaves are dangerous and should only be undertaken by a qualified repairer. PS I have seen a mouse cause this problem!

GE JVM1440WH01 Will not heat, everything else works. This unit is 6 years old and just stopped heating. The carosel turns, fans work, the timer counts down and lights come on when you start cooking or open...


It could be a number of things, Burnt connections between the magnetron, Capacitor, Diode and transformer, Heater connections loose or burnt, Transformer, Capacitor Diode or Magnetron US. You need to strip it and find out if you are getting about 2000volts to the Mag, Are you getting approx 5volts across the heater terminals?? NOTE that the 2000 Volts can remain in the cap indefinitely and the voltage is LETHAL. IT WILL KILL YOU if you don`t take precautions. Ian

Ge jvm 1653 won't heat


You've got a problem in the microwave circuit, which could be one or more of the following components -

1) HV diode
2) HV Capacitor
3) HV transformer
4) Magnetron

I am leaning to the diode, but it would take further investigation to determine for sure. Diodes are cheap, as if the capacitor, and replacing those first would not necessarily be in vain if it turns out to be the transformer or magnetron. And I would be most inclined to say it's the magnetron before I would think transformer.

GE Microwave is arcing inside


Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

The waveguide cover is usually about the size of a playing card and often held in place by a plastic rivet.

In some models it is the plastic ceiling.

It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!

The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

If your waveguide cover is burned, it will need to be replaced.

If you need more specific help, please reply back with your brand and full model number.

Model Jvm1440wh01


There should be a flame sensor (aka oven thermal cutout or TCO) located on the top left side or corner of the chassis.

You will have to remove the outer cover to find it.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

(1) Loose hinge (2) No longer heating food (3) Electrical smoke when microwave is ON


To add to my previous clarification request, the smell may be coming from the magnetron. It will overheat if the cooling fan is not running.

But again, I likely covered it in my previous Clarification Request, but if you still want help, Please reply back with your brand and model number so we can help you.

We're happy to help and we appreciate your thoughtful rating of our answer.
