Either a wiring problem or worn contacts on the relay that powers the two would be possibilities.

Before considering a control panel replacement, check all door switches to make sure they are making contact in both directions (some may be single pole double throw).

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download if available, by model number, Customer Instruction Manuals, list of Dealers, for spare parts and service, and Installation Instructions as required.

I hope this helps.

"SE" means you have a shorted membrane keypad.

The most economical repair (and a pretty simple one) is to replace your entire controller assembly.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

I have one!!

Never run the microwave without a load (something to heat)!!! That kills the microwave generating parts.

Sounds like a 'thermal' protect switch is activating after running. Make sure that (if the unit is mounted in a cabinet) that there is sufficient space around the unit for proper air flow and that nothing is blocking the vents. Try setting it on a counter top and heat something. If it works properly and doesn't shut off, the venting space is the problem. You may have to have the cabinet that it sits in redesigned for more clearance.

That's covered on page 20 & 21 of your owner's manual under the heading"CHARCOAL FILTER REPLACEMENT"

1. Unplug oven or turn off power at the main power
supply.
2. Open the door.
3. Remove the two vent grille mounting screws. (3 middle screws)
4. Slide the grille to the left, then pull straight out.

Check the voltage on the outlet,make sure it is 115v -- 122volts max, any less will cause it shut off, make sure the polarity off the outlet is correct and it is grounded,check all of your wiring connections, if all this is ok replace unit with a different unit or different supplier of unit
