Lost all power in my microwave checked all fuses and thermostats one therm number ksd40lc 1207 shows no continuity is this normal seems this is connected to control panel. thank you for your help.
If this is the thermostat that is sitting next to another thermostat on the base behind the control panel then it is normal for it to be open and the other to be closed. Once the unit reaches a certain temperature the one that is normally closed will open and the one that is normally open will close. If all the thermostats and thermal cutoffs and fuse check ok then the issue would be the control board.
