Did you replace the fan blade or the fan motor? If you replaced the fan blade, is it exactly the same blade as the old one? If it has more blades, or wider blades, or if the blades are at a different pitch than the original, it is capable of moving a greater amount of air, but the old fan motor is not big enough in Horsepower to do the extra work. Thus, you should change the blade again to one that is exactly the same as the old one. If it is a window unit, you could try running the fan on a lower speed and it might work.If you replaced the fan motor, you must check to make sure that the new motor is exactly the same as the old one. You also could have it wired wrong, so you must check that also.

GE bottom freezer stopped cooling


The unit needs two fans running and good airflow, one fan outside cools the condensor coil and the other inside the unit blowing across the evaporator. The compressor must start up. The defrost timer stops everything and switches on a heating element to defrost the evaporator for several minutes. Please verify these conditions.

Had my thermostat radiator replaced 4 weeks ago, driving down the road ac running car started to overheat shut ac off it stopped anyone have this problem


Yes these do happen with the a/c on the condensor gathers heat,thats why the cooling fan is suppose to run when you have the a.c on.You solution is to inspect that the radiator fan goes to high speed,when the a/c iscommaned on.if it does not come on further inspection will be required of the operation of the radiator fan.

I have a 2002 Dodge Ram Quad Cab 4x4. The a/c runs great as long as the truck is moving, but as soon as you come to a stop it starts blowing warm air. Please help.


Generally if the a/c works fine at highway speeds but kicks out or slowly begins to blow warmer and warmer air as the vehicle is driven at slow speeds or is stopped the a/c condensor cooling fan is usually at fault. At highway speeds there is enough air being forced through the radiator, condenser, and oil coolers to keep everything working and cool but when the vehicle is moving slowly or is parked the electric and mechanical cooling fans have to be working to pull enough air through to keep things working. If the cooling fan isn't working or can't pull enough air through the a/c condensor the system will kick out once the internal pressure reaches a certain point. Once the vehicle is moving again the system can get rid of the heat that it has gathered from the passenger cabin, the pressure drops back to normal and the system cools again. I would start by looking for a blown cooling fan fuse in the fuse panel under the hood. Usually they are 25 amps or larger and run only the cooling fan.

Air won't cool when the car is stopped on a 2004 chevy cavalier. car temp is normal


make sure electric coolant fan is running.if not check or replace fan relay.the coolant fan has to be running to cool down refrigerant in condensor.so refrigerant in condensor is cooled back down to high pressure liquid so it can go to evaporator.see ifcoolant fan not working.the AC is not going to cool.when you driving the condensor is cooling down from moving air when car is going.when you come to a stop.cooling fan suppose to be on so condensor gased can be cooled down.

Freezer works Refrigerator will not cool down


The compressor should be OK this time because you caught it in time. But if the condenser fan stops you need to consider replacing the fan. I have had refrigerators do fine until the fan motor warms up and you are away, it stops. Don't think you should use the refrigerator until the fan is fixed. Sea Breeze

Replace Contactor Relay on Rheem Air Condenser


I have a Rheem heat pump/airconditioner, Mod # RPFA-036JAS, that I have had problems with for at least 5 years and have paid over $1,000 in parts and service calls. I can vever recreate the problem when a tech is here. It usually happens in the middle of the night. I hear a Click, ckick, click sound, through the unit and it sounds like it is comming out of my air handler, but the outside unit also clicks at the contactor and the condensor cooling fan moter will start and stop about every half secongd or second. Both contactors have been replaced, the small one twice, one capaciter
has been replaced. I allow the unit too cool down and its alright for a few hours. That is difficult when the outside temp is below zero. HELP PLEASE!

Refrigerator cools, but no freezer fan & no condensor fan running


Check the back of you fridge and make sure the coils are clean. If you have access to a small air compressor, blow everything out and make sure the motor are is clean. The build up of dirt on the coils will not let the heat escape during the cooling process.
