I have a Panasonic microwave NN-S950WA which belongs to my parents. It will start but stops in few seconds (10 to 15 secs.) Clock and functions are working fine. During a lightning strike it hit entire house that killed their microwave, TV, cordless phones, etc. I tried to trouble shoot microwave. The fuse is OK. I believe it is Low Voltage Transformer which is located on a circuit board that is behind touch pad board. Transformer is reading 200-300 ohms which is OK. But there is a varistor to protect circuit in high power surges. I checked this varistor and it seems like bad. I removed it and microwave still does the same. Do you think I have to replace the varistor for microwave to perform if everything else is OK? I learned that it can run without varistor as it's function is to only absorb high voltage spikes during abnormal cases. Please help and let me know if I need to check anything else.
