My GE Profile JVM2070CH resets power completely after running for 2-10 seconds. I noticed that running the fan seems to help sometimes to make it run for a little bit longer. Trying with the fan on many times may eventually work and it completes to 1 minute. When it resets during usage, the clock displays 2:22. But sometimes it resets and goes to the clock setting screen. I have replace the HVC and the diode. But the problem still exists.
I would greatly appreciate any help as I have had the MW for only 1.5 years. I do not know it, but it seems to me that the engineers at GE are the best in applying the concepts of "Planned Obsolence". (Speaking from painful experience)

Re: MW resets power after 2-10 seconds!!!
It could possibly be the touch pad, but since you mention that it runs longer when the exhaust fan is on, I would say your magnetron is heating up.
Say Guest, your "repairman" could have started it cooking, then disconnected the keypad while it was running. Bet he didn't, did he..? *grin*
The magnetron on most GE's have a 5-year warranty now.
Here is a reply I've posted on this problem dozens of times here on FixYa:
Sadly, we hear of this over and over.
This is usually due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.
If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.
It may also need a new high-voltage diode and stirrer, and the cavity may be affected.
GE had a campaign (but not a recall, mind you!) covering several models.
Details are in their bulletin at http://126.96.36.199/mwd/ge_mw_mag_kit_bulletin.pdf
Even if your model is not on the list, the same problem can occur, requiring a kit. I just think the difference is that GE has stopped paying for the repairs.
The parts kit (that GE used to pay for) is part # WB27X10489 and is shown here: http://188.8.131.52/mwd/wb27x10489_ge_mag_stir_kit.jpg
(Your model may use a different kit - this is shown for illustration purposes only).
If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk
There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

You want to take the microwave off the wall, is that correct. 1st unplug the microwave--plug should be in the cabinet over the microwave. Next--in the same cabinet you should see 2 or 3 phillips head screws with big heads going through the bottom of the cabinet into the microwave top. Have someone hold up on the microwave while you remove the screws. They are about 3 inches long. Once the screws are out, the microwave should tilt forward and downward at the front. The back of the MW sits on 4 tabs on the wall mount plate so to get it off completely you have to lift the back up slightly off the tabs about 1 inch. Feed the power cord down through the cabinet and you are done.
Power surges should be checked with a voltmeter, however, I repaired a 30 year old MW doing same thing. Took out the control board, examined solder connections, found a suspicious solder joint, that had an incomplete circle around connector, added a little solder, works like new, friend amazed!
This could happen because of a bad keypad . Just replace it and problem will be solved . I need you to think before replacing it . Because sometimes a new unit is better than repairing . Think it before !
It could be either the magnetron thermostat or the cavity thermostat would be faulty, depending on the microwave but in most cases it would be a thermostat. First of all you can try cutting the power to the unit for 5 minutes, then retry it. Call 800-626-2005 GE costumer care You will probably need to provide your serial number when you call so be sure you have that ready.
