Furnace Blower Won't Shut Off
wrote:
All of a sudden my furnace blower runs constantly even though it is
set on "auto" at the thermostat. The heat cycles on and off properly
(fortunately because it is 19 degrees outside). The furnace is about
10 years old and is gas. I seem to recall there is a wiring option on
the motor for it to run constantly but no one has messed with that
since it was installed. I would appreciate any ideas on what the
problem might be.
Hi,
First unhook wire on G terminal on your 'stat. If it stops problem is in
the ;stst. If not problem is in the furnace, control board of replay
depending on how old the furnace is.
