Customer Question

My Samsung microwave is giving me a flashing"SE" code. It can do it at anytime but usually seems to happen in the late hours of the morning. Daylight savings time is has been turned off. I've read that the problem is the touchpad but I'm leaning toward the board the the touchpad plugs in to.

Your answer was of no help, but thanks anyway.

From Samsung FAQ:
"Some models are equipped with a sensor that can automatically adjust the oven's heating time based on the amount of steam in the oven. If your microwave is displaying E1, E4, or E5, there may be an issue with the gas sensor. For an E1 error, press the Cancel button and check on the food.
Other microwaves do not give specific error messages and just display "8888" on the LED. If you get this error message, your microwave needs service.
If the message is either ERROR or E-6, it indicates a mechanical fault.
For all error indications, including the SE or 5E error, try unplugging the microwave from the outlet for at least ten minutes and then plug it back in. If the error persists, the microwave may require service. Please use our ASC Locater to find your nearest Authorzied Service Center."

Ok William,

Here are the only things I could get using the pause/cancel button.

 

If I hold the pause/cancel button and the start button I get SMH7178 050717A.

 

If I hold the pause/cancel for 8 seconds I get the SE code! Note SE could be 5E code.

 

I think I just figured out what's happening! People complain that The "SE" code usually happens in the middle of the night. It gets colder in the middle of the night and the keypad membrane in probaly contracting and putting pressure on the pause/cancel button for more than 8 seconds. That's my theory
