Shuts off, must reset clock

The popcorn button has never worked, when you press the popcorn button, the display freaks out and the clock must be reset. However in the last couple of days, while cooking and after a few seconds to a minute, the microwave stops and the display reads "please set clock". Can the two problems be related? Please help!

Re: Shuts off, must reset clock

I had this problem also, but what happened with mine is that it popped about 1/2 the bag and then the light popped inside the microwave and it shut down completely. My husband went out to see if the circuit breaker popped, it didn't, but he switched it anyway and the microwave came back on. So he put the micro on a power surge protector, and we tried again, but this time we used the minute timer and it just popped about 1/2 the bag and then blew. The surge protector still was working and so was the outlet, but the microwave was blown. About a 1/2 hour later, I looked in to see the micro and the clock had come back on. We just purchased this at Home Depot this past weekend, should we take it back and get another one? or is it our electical outlet?

Re: Shuts off, must reset clock

This does sound like a loose power connection. It is likely on the control board. Feel free to e-mail me privately if you'd like to have it repaired or if you have other questions.

Re: Shuts off, must reset clock

Jack, I just started having the same problem with my GE Spacemaker microwave a week ago. I've had it for only 16 months, and it was manufactured in January 2005. It shuts off after a few seconds of heating and then you have to reset the clock and date. And then it does it again. I did some research on the web...searching GE JVM1650 problems...and found some unfortunate information from Other people are having the same problem and it may be an "non-repairable problem." I wrote GE an email a week ago through their customer service and have not received a response. (I also want to mention, in Epinions, there was someone who wrote that their GE microwave wouldn't heat up, and it turned out to be the magnetron.) Elaine

Re: Shuts off, must reset clock

Sounds like you could have a fauly control circuit. Something like when you press the pad the processor does not interpret the information correctly and resets itself. Or the power going to this circuit is being interupted. It is VERY dangerous to work inside of a microwave. So you could get an estimate from a repair shop. But those control boards are expensive. Do not attempt to repair this yourself. For your own safety.

SOURCE: timer will run, but won't cook

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa:

SOURCE: Microwave Oven Does Not Start Cooking

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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:.

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

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

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

Our 2006 Samsung Microwave has suddenly ceased to heat anything. The clock works and the turn table goes around, but that's it. We had a couple of power outages just before this happened. Could it be...


Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the GE microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset.
Reset the time of day. Press the "Clock" button, and turn the dial to set the hours. Press the dial to enter. Follow the same procedure for the minutes and a.m. or p.m. Press the "Start" button to start the clock.

You would have to remove the top cover and check to see if the main fuse is blown. Usually a 20 amp slo-blow. There are thermal cut out devices, they will reset when the unit cools, so plug it in the next day and see if the clock and power is back up. good luck, Dale

When I place food in the Microwave and press the express button or any other button like popcorn it will run for approximately 5 seconds and then the display will start going dim or flicker. After that...

if you are using an extention cord pls refrain from doing so, kindly plug this to a wall outlet,

or this is an electrical problem, there is insufficient current to drive a high wattage appliance, thats why it seems the unit is resetting

or there is a problem with the control board it self

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

Let us know if the hard reset does not fix it.

It may have an intermittently shorting keypad or another problem on the control panel, which we repair for customers nationwide with our guaranteed $39.95 service.
