My samsung microwave model ME20H705MSS will not heat up what do I do?

Sounds like you have burnt out the heat sensor.

VERY BAD LUCK. Cost wise you might as well replace the unit. Try a Panasonic brand, mine is 15 years old as was the last one before that, very durable.

there's a ghost in your microwave, call ghost buster. Seriously, the problem is the control panel. (((((the microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. That's more than 30 wall outlets combined.
Replacing electronic parts in a microwave oven can be extremely dangerous.))))))) tank you

please make this test use the multimeter and fix it.
God bless you

1. Check the power diodeThis electronic component is responsible for transmitting current in one direction. If the diode becomes defective it will cause your microwave to not heat. Test the diode and replace it if necessary.
   
2. High voltage capacitorResponsible for storing electricity, this part is a key component in any microwave. Remove, discharge, and test the capacitor to determine if it requires replacement.
   
3. Damaged magnetronResponsible for generating waves and producing heat. When your microwave is no longer heating properly, replacement will be required.
   
4. Thermal CutoffsExamine the thermal cutoffs on both the magnetron and the oven itself. Take off one of the leads and using a volt-ohm meter on RX1, check the terminals. If you get a result other than zero, replace the thermal cutoffs.

Hi and welcome to FixYa. I am Kelly. The majority of the time when you have a working control panel and no heat there are 2 - 3 items that fail.

Service manual for this microwave is actually posted on the sears website:

Cost will depend on what part has failed.
