I have two Honeywell T8601 thermostats in the house, one upstairs and
one downstairs. The floors both have separate blower and a/c units.
Last night I pressed the info button on the upstairs thermostat and
the display went blank. I checked the fuse box and nothing has been
thrown. I swapped out the downstairs thermostat with the one from
upstairs and it displayed fine. The therm. taken from downstairs
would not display upstairs. So, it's not an issue with the thermostat
Any thoughts on if the cause could be in the components on the
mounting plate or at the a/c unit or blower? If so, any suggestions
on how to isolate the problem?
Thanks in advance.
We had a water heater replaced a few weeks ago up in the attic where
the blower is. I took a look at the wires going into the blower unit
and found that the one from the outside A/C unit was pinched and the
insulation on the wires was stripped off which probably happened when
the installers squeezed the new water heater up into the attic. Could
be related but I wonder why the thermostat not displaying would be
related to the wiring between the blower and the outside a/c unit.

Dont be confused. It IS the thermostat. It's almost always the
thermostat. Change it and you will see the difference. Change the low
voltage wiring too with matching 18ga 8 wire for proper electron flow.
