Fan Motor locked up last night, nothing done could get it to stay running.
So we found a DIY HVAC supply today, got a new fan motor, got instructions how to wire it, did as told (brown and brown to cap / white, red, black to line)
Almost POSITIVE that its wired correctly, BUT it keeps smoking out the little screw holes where it gets screwed into the lid. WHY? Is there possible a reasonable explanation for this? Or is it wired wrong? Help!
It sounds like you have a multi-speed motor... You cannot have both red and black wired in...its either going to be red and white, or black and white. If you have both red and black wired in your going to burn out your motor. The red wire is for one speed and the black wire is for another speed... Figure out which one you need.
Some Tempstar and other units have two speed condenser fan motors. They have a thermostat sensor. Somewhere around 80* or below ambient it will be on low speed. As ambient temp increases a relay switches it to high speed.
On the ones I see the two brns to capacitor, white to common, black is high, and red is low. Both black and red are only used on two speed systems with a relay. If you have a single speed, only use one, either black or red usually black. As said if both are tied together you will burn the motor up.
Liebert used ambient temperature fan speed controllers for as long as they had computer rooms.
