Samsung Microwave not heating

[userC66j5s5KBm]

Great afternoon,

I have a Samsung microwave that stopped warming up food! All of the other features work but the food does not heat up! It worked until recently and it's only two years old. It's now out of warranty!

I'm sorry to hear that, have you tried the following? 

Sensor Cooking and Auto Cooking results may vary. As long as the food is getting warm, the microwave does not need service. In some cases, if you are cooking a very small amount of food, you can improve cooking performance by increasing the quantity.

Over-the-range models have different clearance requirements and should be installed according to the installation manual to ensure they vent correctly. If the microwave has not been working since it was installed, check the installation of the vent.

1. Verify that the microwave is not in Demo mode.

   When a microwave is in Demo mode, you can use all the functions of the microwave, but it won't heat anything. This is because the magnetron is not turned on.

   An easy way to test for Demo mode is to set a cooking time and start the microwave. In Demo mode, the timer counts down much faster than usual.

   • If your unit is in Demo mode, refer to your user manual for instructions on how to exit.
   • If your microwave is counting down faster than usual and not heating, but your user manual does not mention Demo mode, this will require service. 

2. Check the Kitchen Timer feature.

   Make sure that Kitchen Timer was not accidentally used instead of a normal cooking cycle.

3. Inspect the door.

   Make sure the door closes completely. If the door is not completely shut, the microwave may run but will not heat. Use a damp cloth to wipe the door and frame of the microwave; debris could be preventing it from closing properly.

4. Verify there is enough clearance on all sides.

   Check the clearance to the left, right, above, and behind the microwave. The space requirements vary from model to model and are included in the user manual.

   If the microwave does not have enough clearance, it will be unable to vent properly. It will either not heat or have weak heat.

If the troubleshooting steps did not help above then you have a couple of options based on your warranty. 

- If your unit was recently purchased, you can check with your retailer on their return/exchange processes.
- If you have an extended warranty you can reach out to them to have service set up. 
- If you're within the one year warranty, you can Private message me or one of our moderators with your full model and serial number to have service setup
- If you're OUT of warranty, you can use this link below to find a service center in your area.

My samsung microwave (2 years old) has heating issues, about a month ago it wouldn't heat for like a day, then it would work fine for a week, and then it would again stop heating, then strangely it would work fine agian for several days...........this cycle has continued for a few weeks now.

It is now at the point though it rarely works, tried it like 8 times today, it worked only once...........looks as if the problem is progressively getting worse. Anyone have any ideas?

thanks
