F 3 mag error. had a bad magnetron and hv transformer. went head and changed both hv transformers,diodes,caps,magnetrons. worked for about 5 hours and its back to blowing f3 fuse. Any ideas
F3 errors can indicate a mag problem. Did you replace both mags?It can also be a door switch. If your fuses are good, you need to inspect the 2 magnetrons. If you have a burned tip on one the waveguide and waveguide cover it will need to be replaced.
