SOURCE: Does not heat up
Test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
If it additionally does not spin and no light, then check also the door switch and fuse.
The diode and capacitors can br tested. The capacitor must be alloweddischarge before testing, or you risk to get electrocuted, even ifpower is off. Capacitors can get discharged by shorting their twocontacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.
All locations, and description of this parts can be located using the diagram here: Counter top.
Parts must be tested to find out what is wrong.
Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

SOURCE: By mistake I started the
I called my neighbor and explained what happened. the first sentance out of his mouth identified the problem and the part I needed to replace. It was a heat switch that I expected but could not find. I even told your incompetent tech that it was something like this but he was fixated on door swithces fwhich I am sure is a stock answere given to him to use for for all problems.
I am asking for and expecting a full refund from FixYa.
SOURCE: No heat
Every time you replace mag on a new rfs or rcs model you have to change the door switch and sometimes the diode. These are made by LG it has typical LG microwave problems
