Problem: Blower motor will turn on normally or not at all.

Normally: Purge motor turns on and I can see ignition through the sight glass.
Nice blue flame and hot air is blowing through the vents.

Intermittently: Just the purge motor runs, Has a blue flame in the box. Seems like the blower motor is not getting the OK to turn on.

Appreciate any help, and thanks for the forum.

Hi,


Make sure all wires are tight and not loose. If so, that is often due to a bad fan switch.



Fan Switch # 7975 - 3281 can be seen and ordered here by paging down :

Thanks,
