: Heater is about 7 years old. Recently stopped working. Can
get it to
: run by running a heat gun into the control panel onto the
: board, etc. It will continue to run as long as I keep the
: set at about 55 f. When I turn it below that the furnace will
: again unless I blow heat unto the curcuit board area. I have
: out the thermostat and wiring. Any ideas? Thanks Tom
If I read you right, it's temperature related. About 55 degree
setting or lower it won't work; that include the ambient air?
If so, the bottom detent has moved. Many thermostats, when set
as low as they'll go actually turn OFF. That's by design. Sound
like that's moved on you or maybe wear has moved it upwards.
It's remotely possible it's a solder joint, but if it's reliably
repeatable that it won't work in temps below 55, I'd bet it's
