Ac Attic Fan Not Working

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.

Ac attic fan not working.

The condenser lines should be cold and the air inside the home should be cool. Whole house fans work on the principle of removing the hot and humid air out of the house. If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor unit. When the home s thermostat detects that the living space is warmer than its programmed temperature level a cooling cycle begins.

Poor insulation is usually the culprit although if you enter the attic on sunny winter day your attic space can be warmed by the sun more than your furnace. 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. The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows. During the day any cooler air brought in by the fan will be heated up immediately by the surrounding structure.

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. The whole house fan is installed inside the attic between the living space and ceiling. 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. Unless your roofing system has insulation on the roofing deck and is designed without ventilation your furnace should not be heating your attic.

The first is an inspection of the outdoor unit to physically see if the fan is turning. 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. 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. Feel for air coming out of the vents.

Most fans cannot keep up. A radiant barrierwould be a better way to attack this problem but their cost effectiveness is marginal. The blower motor starts turning fan blades that circulate cold air. If the coil froze the fan could be working but the air wont go through the ice until it melts.
