If the microwaves do not HEAT and working, do not worry.
God bless you

My Samsung microwave is about 7 years old and everything works fine except it won't heat the food. What can we do to fix it?

From page 23 of Service Manual, --SE-- is a membrane keypad error.
Replace control panel.

"SE" means = sensor error, try to dry it out with a hair dryer, if not working, you have to replace the sensor

The SE indicates a short in the keypad membrane, but to cure this! the whole keypad control board should be changed if effort to resolve is decided, I would also suggest checking the pricing.

This is a sign the keypad has a shorted membrane.

That sounds like the control panel or touch button pad is faulty.
Did it get wet from condensation at all?
Hope that helps

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

looks like your control unit pcb is not having power, most likely a varistor blow up on the input power line to the board, just replace it and fix the melted track on the board.

If yours won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

You can see and hear a YouTube video of how a turntable motor should sound when you rotate it by hand.

To replace either, you need to unplug power, then remove the bottom cover of the oven. You may have to cut the cover off with snips, then use a screw when reassembling it. You can get parts here.

If it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.
