Ac Attic Fan Not Working

Unless your roofing system has insulation on the roofing deck and is designed without ventilation your furnace should not be heating your attic.

Ac attic fan not working.

If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor unit. You can diagnose it by plugging other electrical appliances that are working into the same outlet and by plugging the fan into a different power outlet. Feel for air coming out of the vents. The first is an inspection of the outdoor unit to physically see if the fan is turning.

The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. Symptoms of a central a c fan not working there are a few ways to tell if your a c fan is temporarily or permanently out of order. A radiant barrierwould be a better way to attack this problem but their cost effectiveness is marginal. Whole house fans work on the principle of removing the hot and humid air out of the house.

Try setting the thermostat fan switch to the on position. The whole house fan is installed inside the attic between the living space and ceiling. Most fans cannot keep up. Your capacitor could be the reason your air conditioner fan is not spinning the purpose of a capacitor is to store energy that s in return used to power your cooling system.

If the coil froze the fan could be working but the air wont go through the ice until it melts. The are a lot of things that can contribute to your capacitor breaking down on you but once it does your air conditioner fan will stop working. Trying to solve the heat gain problem in your attic by using a fan is like lying out at the beach with a fan blowing over you and thinking you re not going to get a sunburn. Your attic fan may not be turning on because of an electrical problem like a tripped circuit breaker a blown fuse or a bad connection.

The condenser lines should be cold and the air inside the home should be cool. Even though an attic exhaust fan can incrementally lower the temperature of a very hot attic using a fan does not stop the source radiant heat. The blower motor starts turning fan blades that circulate cold air. It helps to cool your home temperatures and the attic by approximately 30 degrees.
