Question about GE Spacemaker JVM1640SJ Microwave Oven
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?
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.
