1st: Remove furnace access door (effectively cuts off control power).
2nd: Put thermostat back together making sure that all switches
are in
the -off- position, and turn the temperature select to its
lowest
setting.
3rd: Replace furnace door.
Does the blower immediately turn on still?
Nope. Now the blower doesn't go on at all when I hold down the furnace
door
switch. I did hear some snapping at one point, but then it went away.
It was like a sharp click click click...
That's the igniter...
So I opened the blower door (to interrupt the power) and gently tapped on
everything, especially the solenoids; and I wiggled all the wires. I
found
one that seemed loose; and now it's back on tightly...
