My microwave will run for about 3 to 5 seconds and then turn off and I have to reset the clock and date. Then it will go again and do the same thing. What could maybe be wrong?

Sounds like your losing power, have you tried it on a completely Different circuit??? Either that or bad fuse or connections inside of microwave.

Sounds like you have a bad smart board, you can try unplugging the unit for five minutes and then back in, if you are lucky this may correct the problem...good luck

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.

If that doesn't work, leave it unplugged for about 5 minutes.

This is almost always due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

Details covering some previous models are in their bulletin here. Even if your model is not on the list, the same problem can occur.

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.

See this FixYa solution. even if your model number is different.

Well the only way to fix it, replace the keypad control board, but consider the cost in parts, it will rival some new microwave ovens.

The clue is that you have to reset the clock. You are losing power somehow. the Main Board thinks it is being unplugged and it resets the clock and you have to start all over. The fact that after so many times it will finally work tells me that whatever bad connection you have is finally getting hot enough to expand and make a good enough connection to keep working. Intermittant connections are the worse to find. A lot of trial and error to find the problem. can be bad fuse and fuse holder ( in the unit), bad outlet, loose wire at circuit breaker, loose wire at outlet. Even a loose breaker where it snaps onto the buss bar in the Breaker Box. Etc, it an really drive you nuts trying to find it. Try the unit in a totally different area making sure it is on a compleately different circuit breaker and see what it does, if the problem follows the unit, the problems is in the unit. If not, electrical problems, outlet, breaker, panel,

It could have been steam or humidity.

If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

When in doubt feel for air flow through the vents.

Good luck.

If that doesn't work, leave it unplugged for maybe an hour.

Then let us know if the hard reset does not fix it.

Otherwise, try holding CLEAR for 3 seconds, then try each pad for 3 seconds.

sorry to say the control panel sounds like it is defective.There is a microwave guy here that repairs these panels, look him up and contact him for the panel repair information. Good Luck
