Question about GE Spacemaker JVM1640SJ Microwave Oven

2 Answers

I have a GE Spacemaker oven model JVM1490 and the oven just stopped working. The heating element is on and bright red, the fan is blowing but the preheat cycle is only a couple of minutes and the oven never heats more than 125 degrees. Any suggestions?

    The gasket looks good so I agree I think it is either the thermostat or sensor. Where are these located and how is the best way to test them?

    I have a meter.

    Thanks

    Daniel,

    I just relized that my fan was not turning properly as the motor was lose. Tighten it up and is working much better. The issue is I set the temp to 350 but the new oven gauge says 250. Any idea why it is not coming up to tempature?

Hi
This means a loose/broken wire on the oven temp sensor or the sensor is bad and should be replaced. To solve this issue start by checking the oven temp. sensor for 1100 ohms, if the rating is more then that then check the control and door switch and replace the part that is bad. Hope this helps...please post back for further assistance.

If your oven is not reaching the desired temperature there could be a couple things wrong. There is a gasket around that oven door. Check it for any gaps, tears, rips, maybe it is pulling away. If this is going bad you will lose a lot of heat through the door and it will never reach a hot temperature. If the gasket checks good the next steps would be to test the thermostat and sensor. For this you have to be handy with a multi meter and be able to remove each part. You may have to have a technician. The heating element is nice and red so I am led to believe this is not malfunctioning. Hope this helps.
Regards, Tony

    I will list each separate so you can test one while I am typing the other. The sensor is located in between the two areas the heating element is attached to the oven. Remove the screw and gently pull the sensor through and test the wire. Turn your multi meter to the lowest ohm setting and stick one terminal in either side of the sensor connector. You should get a reading of 1000 Ohms of so. If you do not your sensor is bad.

    Make sure to unplug the oven first.

    Sometimes with these smaller ovens you have to remove the top to gain access to the sensor. The will be right off the heating elements.

    For this model oven it looks like there is no way to calibrate the thermostat. If the sensor tests good, the element is good, and the gasket is good. then replacing the thermostat will be the fix. If you look on the inside of your oven you will see a tiny wire poking through not very far. This is your thermostat. It it accessed from under the cover of the microwave. A couple screws hold it on. You have to use a GE part for this.

    If your fan was was loose this could have caused the fan to ware abnormally and even though it is working now to the naked eye it may not working properly. If to much heat collects in one area and the fan fails to fully circulate the heat the thermostat will tell the heating element to cease heating. You may want to consider a new fan.

The most likely thing is the magnetron has 'died' but there is a high voltage fuse between the capacitor and the magnetron which may blow. Either way, repairs to microwaves are dangerous and should only be undertaken by a qualified repairer. PS I have seen a mouse cause this problem!

GE spacemaker microwave stopped heating


If it is working but not heating, then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

The diodeand capacitors can be tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, evenif power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.
