Be sure the thermostat is switched
to Cool , the Fan is switched to Auto, and adjusted low enough to be
turning on. Be sure the filter is clean.
(Note: What is outlined below may or may not diagnose
your problem and chances are, even if it does you will need to call
your Service Company for repair. This is
only an outline to help locate and understand what the problem may be.
Repairs done to the condenser should be performed by qualified technicians
only.)
Condenser Not Running (Blown Fuses/Tripped
Breakers)-
Switch the system off at the thermostat. Check the breakers or
fuses. Reset breaker or replace fuses if necessary. Switch the system
on at the thermostat. If the breaker trips or the fuse blows again at
this point, you need to call your service company. This is an indication
of a more serious problem possibly causing a direct short.
Fuses/Breakers OK -
While next to the condenser, have someone turn the unit
on. Did you hear a 'click'? If you did,this is the contactor.
It supplies the power to the unit. If the unit
did not start at this point, did you hear any other sounds? Loud
humming could indicate a bad fan motor, capacitor, burnt wire.
A loud humming with the fan running could indicate a locked compressor.
If you can feel excessive heat from the top of the unit, this is another
indication of a bad fan motor...causing the compressor to over heat
and shut down.
If you did not hear a click, there is a low voltage problem,
loose/broken wire, control lockout or bad contactor. If you like,
take note of any sounds you hear and complete the FeedBack form.
Overload Protection:
Some units have time delays installed for overload protection. It protects
the compressor from restarting after a power surge or failure. If it
is operating properly, it will restart after a few minutes. If it is
defective, it will need to be replaced by your Service Company
If the above information does not solve your problem, complete
the Feedback form with as much detail you can provide and I will
reply to you within a day with other suggestions, or call your
Service Company.
