check your thermostat is it set on cooling, check your pressure switch it might be triped due to blocked condenser.

2002 4 ton Bryant air conditioner shuts off, fan still runs but not cooling is problem in the controls in the attic or in the AC unit or both?


With a non heat pump it is a simple 24 volt AC control circuit. In the attic there is a relay that is actuated via the fan control wire directly from the thermostat. On the thermostat there is an auto/man switch that controls the fan. Manual the fan runs all the time. Auto fan turns on and off with the outside compressor.

If the system is not calling for cool and the fan continues to run the fan relay is sticking. common problem. Sometimes after running for several days the relay will stop sticking if not, replace relay.

If the system is calling for cool and the compressor stops I would still expect the fan to run until thermostat tells the A/C to off. Some compressor units include a safety switch or high-pressure cut-out switch A blocked internal valve bad control board or external fan in outside unit defective no air flow in outside unit.
High pressure cut out not good,

Suggest turning temp max cool and observe. If acceptable cool and the compressor runs without interruption all is good, except for the blower in the attic. Safely check relay in attic blower circuit.

Hope this helps.

Ac unit runs, inside blower shuts off after 2 mins, compressor continues to run, t-stat still calling for cool


My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem.

It is freezing inside, and it is not cooling properly


Welcome to FixYa,
Check the Following
Is your filter clean? Look and the evaporator in the inside unit. Is it frosted up? Do you have condensation water in the pan? Go to the outside unit and feel the air coming out of the fan. Is it warm? Now feel the 2 copper pipes coming out of the unit. Is the small one warm or hot? Is the larger one cool ? Is there moisture on it?
Air conditioner runs but doesn't cool at all
If the airflow is good and the air coming out is not cold, your home air conditioning problem may be a temporary problem - your coils may have frozen. Turn the unit off for an hour to let them thaw, then try again. If cold air is now present, freezing coils were the problem; if the problem recurs soon after turning on, you may need to replace the coils. Again, call a pro. If you have ceiling vents in upstairs rooms and the air flowing from them is consistently warm, you probably have leaky or poorly insulated ductwork in your attic. See my Attic ceiling insulation page for more information on insulating ductwork that runs through attics.
Another likely home air conditioning problem if you have good airflow but no cooling is that thebreaker to the outside unit is shut off, which, depending on the installation, can either cause the air conditioning system to not run at all, or to appear to be running but not provide any cooling. If you can hear the compressor fan running outside, the breaker is on, but if the outside unit is silent the outside breaker may be off. If switching it on does not solve the problem, look for the high pressure cut outon the condenser and try resetting that.

The fan is running and blowing cool air out of the unit but there is no air coming through the vents, what are the possible problems? (Lennox Elite series)


The unit could possibly have a frozen indoor coil. Turn ac to off...and fan switch to on...wait 45 minutes and see if air flow improves. Check for dirty filter which can lead to freeze up. Low on freon is also a possibility.

Condenser Unit not working


Check to see if there is any board in the outside unit with a fuse .Maybe the fuse popped causing the unit to stop working .
Also check to see if you are getting 24 volts on the thermostat wire going to outside unit .
