At the start of the heating season I found out that my heat pump will
not shut off. 2 thermostats later it is doing the same thing. I
don't know too much about heat pumps or how they work. It works fine
for heating the house. Once it reaches the temerature I set it for it
will not shut off. It will just continue running all day at that
tempature and sometimes lets say I will have it set for 65 in the
house it will be 68 degrees in the house. So the heat pump continues
to run and get hotter. Most of the time it will just sit at 65 though
with everything still running. Heres the strange part. When I set
the temp for anything below 65 it works fine. I put it down to 63 and
the heat pump and the unit in my attic shut off.
Sounds like maybe a stuck relay in the thermostat or condensing unit...to
check get a large hammer and keep whacking the thermostat till either the
thermostat is destroyed or the unit shuts off.
If the above doesn't work then you need to get an about 4ft long piece of 2
x 4 lumber and keep hitting the thermostat all around the electrical box
which should eventually take care of the problem/

Dont listen to all these back yard shade tree mechanics in here. I
have a nationally accredited thermostat installers liscense from
Homeywell and an RSES to boot. Those programmable stats cost a lot but
they make them cheap. It usually takes 3 or sometimes 4 of them before
you get one that is accurate and works correctly. Replace the stat
again. If you need further help, look for a guy named Stormy or
"notHVACguy". Those guys are tops.
