Question about GE Spacemaker JVM1640SJ Microwave Oven

2 Answers

GE Spacemaker Microwave - Model JVM231BL001 (1994)... The light bulb sockets underneath do not have power (I checked w/ voltmeter) and the wires that connect to them don't have power either... I removed the keypad but couldn't locate a fuse... Is there a fuse that I can change? If so, what does it look like? Also, where can I find new bulb sockets for this model? Thanks, DE

    I found a 20AMP fuse behind the top louvers but it seems to have continuity... any other ideas on why I'm not getting power to the bulb sockets on this model?

There is NO Fuse, per sa, and one MUST be VERY CAREFUL working on MW's, you see they have a very large Capacitor, inside, that can and will KILL YOU if touched. Whenever one works on a MW one MUST use a "Shorting bar" and discharge the potential to earth, this Charge can stay in this capacitor for a VERY long time... and MUST be discharged after every power on/off/on cycle Usually these faults are with the actual power Supply, and.or Magnetron/Power Diode.

    My actual model # is JVM231BL001 (1994)... not sure how the above got listed on my original question. I couldn't find this model # on GE's website or the actual model. The MW works fine but is annoying that the under cabinet lights don't work when cooking at the stove.

Here is what I have so far.Not related but BS about how they don't want do it yourself done.
http://www.geappliances.com/search/fast/infobase/10000260.htm
I am going to keep looking anyway,hang on please.Since yours is so old it may or may not have this surge protector which,if bad,obviously would not give power.

Here is the only fuse reference I could find in 15 pages so far.
http://www.geappliances.com/search/fast/infobase/10001087.htm
However I did find a sneaky loophole which should help.You obviously know electricity/electronics so here it is.Wiring diagram location! :()
http://www.geappliances.com/search/fast/infobase/10001188.htm
Good luck.Depending on what you may find,you may want to consider a newer one too and if you end up finding what part you need,obviously weigh out the difference of repair/replace.

    How did you measure continuity?Do you have a multimeter or just a voltmeter?

  • Greg McCarthy Aug 05, 2010

    If you checked it with a voltmeter,0 means it's good,anything other than 0 means it's blown.Sorry,just trying to figure out your knowledge.

  • Greg McCarthy Aug 05, 2010

    ...probe on each end of the fuse while it's on.

Why if you put in a new light bulb the light bulb does not go on


It is because the light bulb may not be the problem to begin with. You should check the light bulb socket and related wiring and connectors for any cold solder joints.

If you have a multimeter you can check to see if there is any AC voltage going to the socket. If you don't know whast your doing then I would suggest you get someone that does. Remember your dealing with 120 volts.

good luck

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.

    GE Spacemaker Microwave lights flicker on then off


    There must be a short in the wiring between the bulb sockets and the power supply or control board. Otherwise the short may be in the bulb sockets themselves.
    I would test the connections to make sure the wires aren't loose and all solder joints are tight. If all wires look good, and bulb sockets are tight, then the problem may be faulty capacitor

    Need new light bulb socket for GE spacemaker mircrowave


    The bulbs are glued in at the factory. Unplug the microwave and see if you can remove the base of the bulb from the socket with needle nose pliers. You may have to twist the heck out of the bulb base but it should come out. If you do need a new socket it is available at www.geappliances.com under parts and accessories. Or call 1-800-626-2002 for GE factory parts
