Hi -

My wife and I are temporarily in an apartment situation while our
insurance company decides what to do with our Hurricane Katrina-damaged

house.

This is an old house and the blower unit for the A/C (which I guess is
usually
aligned with the furnace in most homes) is outside with the A/C. In the

past week we've had the A/C repair guys out here five times. All are
related to
the blower quitting - the A/C unit itself is still going but the
actual blowing of air is nonexistent. Everytime I or the landlord call
the
A/C guys, all they do is replace the blower unit, which then works for
approximately 10-20 hours and then quits. Not only that but the air
that
is being blown in is redolent of a stiff breeze on a summer's day on
Lake Michigan, not the cold quasi-Arctic blast I am used to. I have
pleaded with these guys time and again to check the freon or the line
pressure or some other thermodynamic jargon, but something just
happens while I am at work and it's "fixed" when I return.

I have also noticed an unusual burning smell when the blower decides
to commit suicide.

Any hints or things I should get these guys to check?

Thanks,

JMK

You need to check the yellow pages and get a better service tech to check
the unit.

I wonder if they have 220 instead of 110 going to it, see what the
blower motors name plate calls for and take a meter and check what the
voltage is going to the blower. Just a shot in the dark. The motor can
burn out either way as in 110 going to a 220 motor and or 220 going to
a 110 motor.

Possibly the old motor was too small. If they replace it with the same
size motor, the new one will burn out too. The nameplate should have
the proper motor size. After they replace it, they should check the
amps to make sure it is working OK. They should also replace the motor
capacitor.

One other possibility is if it is a Goodman or Janotrol or GMC heat
pump. The blowerr relays have a habit of failing in such a way as to
run the strip heat and motor together, hence a burning smell. If that
is tha case, replace the blower relay as well. Sounds like the service
company uses parts replacers instead of techs. If it is not working
right when they are done, they haven't diagnosed the problem properly.
After 5 trips, it appears they cannot.
