Question about GE Spacemaker JVM1640SJ Microwave Oven

1 Answer

GE SpacemakerXL Microwave oven quits after a few seconds

I purchased this microwave oven Model No: EMO3000HSS  on 7/6/06.  On 7/1/08 the display started to flutter and it shut off after a few seconds and I would have to reset the clock and try again. Usually after a few times it would work or it might work normally the first time.  A service repair co. came and replaced the main board (touch pad) PN: WB07X11800 this did not fix the problem. They came back in a few days and he saw sparks on the Noise Filter board and replaced it PN: WB02X11200.  It worked normally for about a month. They came back again and replaced the same Noise Filter board.  It worked for about 2 weeks and the same problem started again.  The microwave does heat and if after you keep resetting the clock it will eventually work and sometimes it will work the first time. Now this service co. is saying that the Magnatron and or the Thermostat needs to be replaced. If the Magnatron is defective it is still under warranty.  I thought if the Magnatron was defective, it would not heat.  After three and a half months and six service calls, I really doubt that this service co. knows what they are doing as no diagnostic tests were ever made or meter readings taken at any time.   All they did was keep replacing parts....if this doesn't work we will replace another one. Would diagnostic tests pinpoint the problem or is it normal to just do trial and error part replacing?  
I took a digital picture of the display when the problem occurs and I could email it to you, if you want.
After spending all this money, your help and suggestions would be greatly appreciated.  Should I just buy a new microwave?

    First of all, I really appreciated your prompt attention and your solution seems like it will solve my problem.  Although, after reading the bulletin (RA08-02) that you notated above, the problem is that the Model no: EMO3000HSS03, the Serial No. prefix of HH, and the Manufactured date of May 2005 of my microwave is not listed in the bulletin.  The service company that I was provided through my home service company (Total Protect) was not an authorized GE Service Co and yes the parts that they installed were applied towards the $500 limit per appliance and was all but exhausted and I questioned them every time they came about doing testing to find the problem.

    We have the same problem with our GE microwave. However, it was manufactured Aug. 2004. Have they extended the models noted on the bulletin or prehaps issued another bulletin that includes later models?

    I have this exact same problem, it just started happening about 1 month ago. I am very frustrated...the microwave is only 3 years old. Our model is:JVM1653SH01, manufactured Dec 2004. Is there a product recall on this? I am concerned that it is shutting down like this because of an electrical issue that could cause a fire.

    I called GE Service and they sent out a service tech in two days.  He looked at my problem and said that it was the magnatron.  He replaced it along with a diode.  Since the magnatron was under warranty, he only charged me the labor charge of $115 and waved the service charge.  The problem was fixed.

    Thanks again for your advise which was right on!

This disgusting type of repair procedure is called "shotgunning".

I have always preferred testing and experience to determine what is wrong, as opposed to guessing!

I assume that they did not charge you for the good parts they mistakenly replaced?

IF they are a GE-authorized service center, they should have recalled a bulletin from a while back about defective or mismounted magnetrons causing electrical interference that disrupts the controller.

What your oven needs is a new magnetron and (IMHO) their hands off of it. If the thermostat were bad, the oven would be totally dead.

You can find GE-authorized servicers by contacting GE Customer Service here.

Good luck.

    Sorry I forgot to mention this:

    Even if your model is not on the list, the same problem can occur, requiring a new magnetron, and possibly a new rectifier and stirrer.

    I have no doubt that the problem is your magnetron, at least.

Lighting Problem

We see this a lot. The problem is on the control panel, which we regularly repair nationwide for $39.95 postpaid.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa:
