The microwave has power, light & turntable work. It just won't heat. I have tried a number of setting combos . . . . nothing.

F4 is the code for a bad humidity sensor.

If something unusual has happened in your microwave ( like a lot of grease from too high a temperature setting or meat that was greasier than ecpected you may be able to clean it to correct the problem.

After cleaning if the code does not reset to normal then replacing the sensor could correct the problem

It is possible there could be other problems with the circuit board or wiring.
Expert:  Machinc replied 1 year ago.
Wiring problems can be discovered by taking the unit apart.
NOTE:: WARNING
Unless you have experience with microwave repair this should be done by a professional.

Depending on the age and cost of your microwave it may be better to buy a new one.
Expert:  Machinc replied 1 year ago.
The part is reasonably priced but is behind the cover and replacing it may be beyond your confort zone. Microwaves can possibly cause a shock when unplugged and cause injury if not only from the shock but also your reaction.
Expert:  Machinc replied 1 year ago.
Going back to the beginning it is possible a good cleaning will correct the problem
Expert:  Machinc replied 1 year ago.
Definitely try that first.
I will be glad to answer any questions you may have.
