when I went to heat up my coffee put it on one minute to heat everything ran as should but coffee was still cold.
You will want to check to make sure that the diode is good, the HV transformer, the magnetron thermal fuse, the magnetron and the capacitor. All of these components can cause the unit to not heat.
I have an older tappan microwave that just quit heating. Everything else works. What part(s) would it need ?
Answer Hello Helen,
You would want to check the diode, the fuse, thermal cut off and the transformer. The magnetron may be bad but these other components can also cause unit to stop heating.
