Hello, this is my first post and first want to say thanks for all the past help. Secondly, I had problems with my resistor, blower would only blow on high, so I replaced the resistor with a brand new one. When I replaced it and turned the blower on the coils on the resistor glowed red hot. The hot coil would switch as I moved from low to med and then the new resistor would only work on high just like the old one. So I assume it too burnt up, but what could be causing this, although the blower worked at high, med and low could it be drawing too much amps or is it something else? Thanks

 

are all the speeds working now?? sounds to me like its working properly, those coils do get hot thats why they are mounted in the heater box directly in the air flow so as to cool them

 

It only works on high now. It was working but then stopped. Could it be that because we did not have it mounted in the heater box where air could blow across it that it got to hot and failed? At first we just plugged it in, not in the box, to see if it worked, which it did but then quit.

 

yes......they do need the airflow to keep them from burning out
