Question about Microwave Ovens
"SE" error means you
have a shorted membrane keypad.
The full model number from the tag on the oven should be one of these:
SMH9151B/XAA (service manual)
SMH9151B/XAC (service manual)
SMH9151BE/XAA (service manual)
I've included the service manual link for each one for your convenience. They'll help you with disassembly and in getting part numbers.
You can order parts by entering part numbers or your full model number from the tag on the oven here.
There are three ways you can fix this, with the last probably being the best:
1. Replace the membrane keypad ("switch membrane"). The cheapest way but the hardest. If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved. It's here.
2. Replace the control panel frame assembly ("assy control panel"), which comes with a new keypad on it already. Pretty easy, not expensive.
3. Replace the entire controller ("assy control box"). Very easy, and usually not much more than option 2.
No matter which option you prefer, 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.
Some connectors on the relays may have a lock:

I tried running a hair dryer on low heat over the Keypad/Membrane after dis-assembly for 15 minutes. Worked for 2 days and problem re-occured. ASSY CONTROL PANEL;SMH91
I am going to replace it.
Cause: Dirt, Humidity, Water penetrating the membrane and shorting the circuitry.
Order the below part and replace it.
Part Number: DE94-02001A
You can order from APWagner ot SearsParts.
Remove three screws from the front-top metal strip/panel of the Microwave.
Remove one screw above the Keypad/Control unit.
Remove Connector Cables.
P.S: Wish the bottom portion of this OTC Microwave was sealed tight enuf to prevent any humidity or dirt from entering the control panel.
