Question about GE JVM1410 Microwave Oven

2 Answers

My wife heated some biscuits in a metal pan yesterday and it shorted out when it hit the door of the microwave. The display is lit on my microwave. I can set the clock. I have checked the fuse and it checks out fine. It appears that I have 120VAC going everywhere that it should be going. When we start the microwave, it will act like it starts and count down but the fan never comes on and it does not heat. Any idea what may have shorted out? Thanks, Andy

SOURCE: No turntable, no heat. Light, vent fan and keypad all work...

That would be a problem with your primary interlock switch or its mount.

NOTE: 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.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

The interlocks are highlighted in the diagram below.

I have not gotten a solution for this problem. I thought your website said one of the experts would respond for free. Seems like that must have been a hoax to give you the opportunity to sell me something. Shame on you!

I am still waiting for the free assistance, as advertised.

SOURCE: Microwave won't heat, and turntable doesn't turn

All the parts you mention are very inexpensive, but yours does not have a triac.

It could be the cook relay, but it's more likely to be a switch.

Looking at the schematic, it's probably a bad primary interlock (upper door switch) or maybe its mount is bad.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you have a broken mount, it's usually more economical and safer to just add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

There may also be a "mini-manual" hidden inside the unit behind the control panel or elsewhere, which is very helpful when troubleshooting & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you only need a switch, you can order a universal type here for $5 postpaid.

Using it and just went out


Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Check this link to know how a microwave works:

http://www.espares.co.uk/advice/microwave/a/5/1443/how-a-microwave-oven-works.html

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link:
http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html

Now keeping clear of the microwave, switch on; use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

Control plug lits up but pan will not heat


Check the door safety interlock switches. Remove the cover and check with a volt/ohm meter. If the switches cannot report a closed door to the device, the device will not turn on the heat.

My microwave has a small "d" on the right side of the display. It won't heat anything, but it rotates and sounds like it cooking. This just happened yesterday. It's a 2005


It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Oven has been working fine. Heating a cup of coffee it just stopped dead. No display. Nothing. Power to outlet working fine. Is there a reset somewhere?


Mine did this when my wife had it on full power for over 10 minutes. We left it set for 15 or so minutes and it came back on. It did the same thing when my niece was heating a liquid with some metal in it. It eventually came back on. There must be a thermal circuit breaker inside the unit. Yours may have a fuse or some sort of circuit breaker inside it, that needs replacing or resetting. Then again some units have a fuse that goes out when the Magnetron shorts out, or goes bad. This would require replacing the Magnetron as well as the fuse.

Sensor error


I had the same exact thing happen...I put in some popcorn, it wouldn't pop. The screen said "sensor error". I tried heating water, a piece of chicken...nothing would heat. I unplugged it, plugged it back in...nothing. The manual says to close the door and hit the clear/cancel button. I could have sworn I had done that, but my wife simply hit the clear button and it started working again good as new. Hope yours does the same. : ))

You have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screws you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

You can usually find helpful exploded view diagrams (and order any other needed parts) by entering your full model number here.

When you peel off the old seal tape, it's best to heat it up with a hair dryer and work slowly so it will all come off in one piece and to minimize the amount of adhesive that has to be solved and scrubbed off.
