Bypassing Vent Fan Thermal Fuse to Get Microwave To Work
I have an over-the-range Samsung microwaves (model me18h704sfs ) that stopped working due to a blown fuse. I changed the fuse and discovered an abnormally in the electrical circuit that I can’t figure out what caused it.
All three door switches, fuses and thermal fuses show continuity. There is one thermal fuse (“open” under normal condition, “close” in response to high temperature) that turns the vent fan on automatically when the temperature exceeds its ceiling. When I bypass that thermal fuse, the microwave works fine but the vent fan is always on. When I do not bypass that thermal fuse, the microwave runs with no heat the and the vent fan is off. When I disconnect the bypass when the microwave is on, the microwave continues to run but no longer produces heat (I also heard a single click sound as soon as I disconnect the bypass)
Do you guys think I need to replace that thermal fuse to solve the problem or is there a faulty electrical circuit somewhere?
Thank you for the help!
