"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:
