Hello to All (again),
Thanks for your help so far! Based on your input, I'll need to:
a) get a better multimeter - mine is analog. I can either choose the 10v scale or the 50v scale. So I can't read THAT accurately.
b) Clean this thing by pulling it out of the cabinet.
To answer your question, the fan never comes on at all. The sequence I see/hear is:
1) Turn thermostat requested temp down so it sends call for heat.
2) "Click" from furnace.
Then nothing at all after that. No fan, no nothing.
I'll check voltage with a digital multimeter and I'll pull the unit out and clean it.
Thanks everyone!
