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.

sounds like the fan over heat, you may want to check the fan relay and wiring for corrossion and capacitor as it may not be shorted but lower in value and making the fan over heat and triggering its build in safety cut off..

Sime ecomfort plus 30 HE keeps cutting out and shows a flashing green light. Sometimes it will run ok for a couple of hours before cutting out.


I had the identical problem with the same model. Technician eventually diagnosed faulty fan; the fan cools the heat exchanger. When fan fails, exchanger overheats and boiler automatically shuts down. It is possible to restart the boiler when it cools down but when the heat rises again - off it goes! Only answer is to replace the fan. My technician did the same as yours - on first visit he got the boiler running and left. Half hour later, boiler shut down. I read the installation manual and operating instructions and when he called again I pointed him in direction of fan, which had failed completely. These guys!

Electric fan wont kick in jeep over heats replaced thermostat and two sender units


Sounds like your cooling fan relay is bad the jeep grand cherokees are known for this, first thing i would do is unplug the radiator cooling fan and run 2 jumper wires direct from the battery to the fan connector if the fan kicks on your fan motor is good and the relay is bad, if the fan doesnt kick on replace the fan motor with a new unit, the cooling fan relay on your particular model jeep is located under the passenger headlight and requires you remove the front bumper to replace it, however some people cut a small hole under the headlight to access the relay the faster way but if your not to keen on cutting holes in your car remove the bumper and replace the relay if the fan checks out and you wont be overheating anymore...
