If the the power is going thru the relay then we have a 120 volts. I would be looking at the neutral and ground to make sure, I have those. Its very unlikely that the fan and compressor would not work unless you were missing the 120 volt or neutral and ground. the problem could be in the breaker box as well. check for a loose or burn't neutral.

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.

Things to check before replacing the fan motor.
Relay Power Supply and Ground Unit
  • These are the first two components worth checking if your cooling fan is not turning on when you switch the air conditioning on -- which it should every time. As explained by AA1 Caricon1.png, a good relay coil will typically read 40 to 80 Ohms, but if the resistance is high, even if the coils still works, the relay will not, and you will see a failure in the system. It may also fail when the electrical load on the circuit is too high for it to cope, which is referred to as a "cut-out." When the coil has no resistance, the relay will need to be replaced with a new one because it will never work.
Thermostat Unit
  • The thermostat unit can stop cooling fan relays from working properly, since the two appear in series in the circuit, which means the electrical current moves directly between them so that when one is faulty, the other can be affected. If your relays are not performing well, you have the option to bypass the thermostat using a length of continuous wire. But the thermostat's function will then be lost if you cut it out of the circuit -- so bear this in mind before making final changes. Also check the integrity of the thermostat housing, which is responsible for temperature regulation as well, according to Car Tech Auto-parts.

Cooling fan on a Landrover LR2 2008 won't turn on. thermostat has been replaced. what could be cooling fan problem?


Hi belindacavey,

I have seen a few problems with the cooling fan on Land Rovers. Usually the relay portion of the fan fails. For a while Land Rover had fans on back-order because so many where failing. I would recommend having the fan/relay checked. FYI the relay module and the fan are usually one assembly.

Honeywell Chronotherm iv fan keeps running even when heat and cool turned off. How do I turn it off?


Assuming you have the fan switch of your thermostat in AUTO, it sounds like a stuck Fan Relay. If the fan relay is stuck, your fan will continue to run as long as there is line voltage being fed to your unit. This relay could be an independent component or it could be an integral part of your control board. Have an experienced, qualified service technician check it out.

What would cause my radiator fans not to run


A lot of different things fall into this senario.Low coolant level,air in the cooling system,and a stuck thermostat,or,a bad coolant sensor,or even a bad cooling fan relay,or the cooling fans are bad.Turn the defrost on or the ac,the cooling fans should come on if the fans,and the relay are ok,if so,replace the thermostat,and coolant sensor,and bleed the cooling system of air.
