Why does my AC fan run after I Turn Off the AC?
Your AC fan continues to run after your AC is off. Your AC fan doesn’t turn on at all. There are rattling noises coming from your condenser. If you notice any of these issues, you should turn your AC off and have it inspected by an HVAC technician right away.
Why does the radiator fan have to start when turning?
The A/C condenser (the part which sits in front of the coolant radiator) is a heat exchanger. If air isn’t flowing over it, it won’t exchange the heat it needs get rid of so the A/C core inside the vehicle can become cold and make you comfortable. If the fan didn’t come on, you’d still be warm inside.
When does the condenser fan come in with the AC on?
The condenser fan (if it has a dedicated fan) or the radiator fan most always comes in (with AC on) when the compressor discharge pressure (or, alternatively, the liquid line one; look for where a sensor or a switch is located on the high pressure line) rises over an operative threshold.
Why does my PCM not turn on the fans?
You are looking to see if the PCM sends power to one or both relays to turn on the coolant fans. This should happen as the high side of the system approaches 214 psi. If it exceeds this amount of pressure and the system doesn’t turn on, one of the sensors in the system that the PCM uses to know when to turn the system on and off has failed.
Why does my AC fan not come on?
When the ac is of the radiator hoses both become same heat after a while and the overflow reservoir starts boiling over and the fan do not kick in. Any advise please. You might have an initial temperature sensor which causes the fan to come on when the temperature begins to rise; that sensor might be defective.
Why is my air blower not running on a / C?

What should I do if my AC Fan is not spinning?
Slide a long, thin wooden stick through the fan grate and gently push one of the blades to try to get the fan spinning. (Safety note: DO NOT use any kind of conductive metal or material to do this. Don’t put your fingers in or near the grate.) If the fan takes off and then keeps going on its own, you more than likely have a bad start capacitor.
Where are the fans located in a central air conditioner?
Your central air conditioner has two fans: one located inside which blows cool air into your home, and one located outside which blows over condenser coils in order to release heat from your home’s air.
What happens if your central air conditioner is not working?
That means your central air conditioning system is vital to your home comfort. If it isn’t working correctly, your house can become dangerously hot quite quickly, and you’ll need to troubleshoot the problem.
Can a bad fan motor cause a bad air conditioner?
This is especially true for air conditioners that are not properly maintained. A bad fan motor is a serious issue that will either require professional repairs or a system replacement, depending on the age and condition of your system. Loose or broken belt.
What happens when your AC Fan is running 24 / 7?
Better dehumidification. When your fan is on “AUTO,” moisture is able to drip from the cold cooling coils and drain outside. When the fan is running 24/7, that moisture doesn’t have a chance to drip outside. Instead, it blows back into your house, and, as a result, your AC then has to work ever harder to suck that extra moisture out of the air.
Why is my central air conditioner fan not working?
Contactor problems can result in your central air conditioner fan not working If you’re unsure as to what your air conditioner’s contactor switch is, it’s a switch located on the inside of your unit that ensures that there is enough voltage being provided to control the compressor as well as the condenser fan motor.
When to turn on the fan in the attic?
In the late evening or early morning, the fan is turned on to exhaust hot air from the house. Cooler outdoor air enters through open windows, lowering the indoor temperature. Image Credit: U.S. DOE

How can I tell if my air conditioner is on or off?
Make sure fan is on HIGH, temperature selector is turned all the way to COLD, and that the A/C and recirculate light indicators are on. Set the temperature to cold, the lowest setting. Set the cooling fans on high on the climate control. Check to see that the cooling fans on radiator are running when the air conditioning is on.
Why is my a / C compressor not coming on?
If there is voltage to the sensors and nothing past the sensors, then the system is low on refrigerant. If there is no voltage to the sensors, then the a/c switch would need to be replaced. The cooling fans and condenser fans either are not coming on from a loss of power or the motors are burned up.
What to do if your a / C switch is not working?
If there is no voltage to the sensors, then the a/c switch would need to be replaced. The cooling fans and condenser fans either are not coming on from a loss of power or the motors are burned up. First check the cooling fan circuit. If there is no power to the cooling fan, then check the fuses and see if they are burned.
