Question about LG Microwave
After it locked i smelled a burnt wire smell up staires i beleive comming from vents is this normal
Either the bearing has seized, or there is a bad connection on the terminal board where the wires connect to the motor.
I would spray the bearings with a good penetrating oil (I like PB's Blaster) and let it soak for a while.
Then spray it again and immediately turn the squirrel cage by hand and see how well it turns. If it's not smooth, it needs to soak some more and the bearings may be shot. Then you'd have to replace the bearings or the motor.
It is turns smoothly, you need to unplug the power cord and inspect the area where the cord plugs into the motor. Look for charred connections. In some cases (as I did to mine a few years ago) you can clean up and/or bypass the connections, making sure they are clean and tight.
If the connections are bad and cannot be repaired, the motor will have to be replaced.
I bought a spare from an independent heating and cooling guy. Saw his truck, looked him up and called him. He sold me a good used one for $20.
Here's a helpful tutorial on how to replace such a motor. Lotsa pictures.
Some good videos about it here.
