Dieselvolk, I'm trying to diagnose a dead 24-year-old Whirlpool microwave. This is part of a built-in oven and microwave combo, so replacing the microwave means replacing both for at least $1500 or more. I'd much rather repair than replace.
One of the three fuses has blown (cavity temperature fuse) and the wire connectors are melted / burned at the connections. This fuse is between an identical fuse for the magnetron temperature and the monitor fuse, and neither of those fuses exhibit the same melting / burning at the wire connectors. The blown fuse is rated for 10 amps / 250 volts, same as the magnetron temp. fuse. Monitor fuse is rated for 20 amps. I've tested the components that commonly cause a blown fuse (door switches, high voltage transformer) and also the high voltage capacitor and rectifying diode. I don't see any burning / melting on the control board or any other wires / connectors. What thinks you? Would a fuse that ages out and dies exhibit burned / melted wires? Do I need to keep looking for the real cause of the blown fuse? ------------- Max Charleston SC _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
