Question about GE Spacemaker JVM1640SJ Microwave Oven

2 Answers

I have a GE JVM 1490, digital display will not light

This above the cooktop oven is in a motorhome I bought new in 2005. Every time I hook to shore power or start generator, oven says "set clock" now the digital display does not light up. Inside oven light goes on, popcorn button starts microwave, and bottom light works fine. This microwave has only been used a dozen times. Is there any way to fix this cheaply, or should I throw it away and get a whirlpool?

    That is not the problem. In a motorhome, unless it is permanantly hooked to shore power, each time you use it, you must reset the power. MY problem is: the "start clock" flashing light no longer comes on when I connect to shore power. I know the microwave has power, because if you hit the popcorn buitton, the microwave starts, interior light comes on, and the dish rotates. The display never comes on, therefore I cannot set the clock, timer, or other features that require the digital display;. Clock settings, as well as timer is set on this model by rotating a knob in the center of the panel.

    Digital display does not light up on GE JVM 1490 above the cooktop oven. Unit has power, but the display should read "set clock". I know the oven is getting power, because recepticle is hot, light comes on when you open door, and if you select "popcorn", microwave starts as it should. Time and temp are set by rotating knob in center of panel, and without the display lighting up, you cannot set time or temperature. This oven has only been used about a dozen times.

Every time you switch power source, it interrupts the power briefly. This is basically a 'power loss' to the unit and it needs to be reset just like at the house when you have a power loss. I don't know of a way to prevent this other than ignore the clock issue on the panel.

Our Advantium 120 oven (model # SCA1001KSS 02, Manufactured June 2008)is not working. Began w/ time not coming on when cooking and just a little green microwave light shows while cooking.


Typical of a control microchip failure caused by a power surge. With a microwave as old as yours, it is safest to simply replace the entire oven rather than attempt to fix it, as older magnetrons are likely to fail.

Service manual jvm 2070 microwave


First of all if you're having problems with the touch screen, display, or keypad on these models, separate parts are not available, and you'd have to order the entire control panel assembly, which runs a few hundred to several hundred dollars, depending on the exact model.

Luckily, problems with the cooktop lights or fan can be remedied by ordering a new smart board or having it repaired.

That said, the closest I have come to a service manual for these is the technical manual here.

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

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
