About a month ago we had problem with one of our heat pumps. It was
blowing hot air. They replaced the thermostat (it was calling for
emergency heat when it shouldn't), the compressor motor and a
capacitor. Now it is not working correctly again. It doesn't seem to
be blowing hot air, but it isn't cool. Sometimes the compressor is
running but the fan on it is not running. On the air handler there
are two copper tubes. Sometimes the larger one is cool (and wet),
other times it is room temperature. The smaller copper tube is hot.
Does this mean it is calling for emergency heat again? Or what could
be the problem?
PS. I left it off for a few minutes then turned it back on and now
the compressor fan is blowing, it is blowing out warm air, it is
blowing out cool air inside, the larger copper tube is cold and wet,
and the small copper tube is at room temp or perhaps a little warm.
(The small tube was pretty hot before.)
The "small tube" (liquid line) being hot would most likely indicate that
the condenser fan motor shut off and the compressor stayed running. It
could be a praoblem with the motor itself, or a problem in the defrost
controls. What is the brand and model nuber of the unit? Larry
I'm thinking you're not getting good service with this company. If they've
replaced the wall thermostat, the compressor, the run capacitor, the outdoor
fan motor, and you're still having issues - there's something rotten in your
town and it's not the fruit.
It might have been easier to just replace the equipment at this point. Call
a new company and get a second opinion.
They didn't replace the compressor. The thermostat seems to have gone
bad after an electrical storm and was telling the heat strips to come
on when they shouldn't. But otherwise I think you are right.
After I leave it off for a while, it will work for a while, but then
the compressor fan stops turning again.
If you keep screwing around, you will be replacing the compressor with
the conditions you are describing. The outdoor fan motor MUST run
whenever the compressor is running (except during defrost in the
What you need to do, is call up the owner/manager of the company you
have been dealing with. Tell them that you are seriously concerned
about the technical ability of the tech/s in their company. Remind
them of how much you have paid them and/or still owe them. You might
mention that you are concerned that they seem to keep replacing
different parts and it still doesnt work correctly. Let them know that
you are concerned that you have paid or still owe money that you think
might have been unnecessary repairs. Let them know that you would like
this situation resolved quickly and fairly. Keep it professional. If
that doesnt resolve it, start looking for another repair company,
lawyer, BBB, attorney general, local news reporter, etc. etc.
