The -SE-error is a shorted keypad.

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.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

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

I have GE JVM1540DN1BB microwawe. It beeps all the time and says "keypad sorted" and service needed. The beep sound is annoying and it beeps every 30 seconds


see this causes and fix it. God bless you
Touchpad and Control Panel If the microwave buttons don't work the touchpad and control panel assembly are probably defective
Touchpad If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
User Control and Display Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Main Control Board If the microwave buttons don't work the main control board is most likely defective and will need to be replaced.

Microwave keypad does not respond and screen reads SE


"SE" error means you have a shorted membrane keypad.

The exact part you need will depend on the model number, which will be one of these:

SMH9151B SMH9151B/XAA SMH9151B/XAC SMH9151BE SMH9151BE/XAA SMH9151S SMH9151S/XAA SMH9151ST SMH9151ST/XAA SMH9151ST/XAC SMH9151STE SMH9151STE/XAA SMH9151W SMH9151W/XAA SMH9151W/XAC SMH9151WE SMH9151WE/XAA.

On some models, you can just order a new membrane keypad and replace it. It's cheap, but a lot of work.

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.

On other models,
the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job, but it costs more.

Feel free to contact me directly (and please remind me of your full model number) for more information & help and a free estimate for us to do it for you.

My chefmate 1050 watt microwave beeps nonstop for minutes at a time repeatedly. I must leave it unplugged to get relief. Also, the keypad is unresponsive sometimes.


Either the touchpad or control board is defective. If the ribbon cable was disconnected from the control board and the beeping stops it would confirm the problem. Since the keypad is unresponsive, that probably is the problem.

What does f2 mean?


F2 on a Kitchenaid / Whirlpool / Maytag microwave means you have a shorted membrane keypad.

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

On some models, the keypad is available separately.

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.

On other models, the keypad
is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

It all depends on the model number.

Microwave is turning itself on


First, do not leave this machine plugged in until it is serviced. If this is a KHMS155LSS, there is a very high probability that you have a keypad short. This defect can cause the machine to start on its own at ANYTIME, at night, while you are away, at work etc. Contact Whirlpool Customer Service and ask for Safety Dept immediately. They will most likely send A&E out to fix it. Although it will fix the problem, if the keypad fails again, the self start logic defect is still present. You should be under warranty if it is above model. I almost had a fire this past Monday, Labor Day, 9/7/09 when my machine self started at 3 AM with a package of bacon left in to thaw for the morning. What a somey mess. Chinese made garbage.

Microwave oven defective keypad


Sorry, but that makes it unrepairable.

It may be possible that your insurance company may cover part of the replacement cost if you had flood insurance.
