Question about Heating & Cooling

1 Answer

My attic fan failed to work. I replaced the motor and it ran great... for about a day. This is a problem I've had 3 times already and each time I replaced the motor, it blew out again before the season ended. What could the problem be?

Your problem could be related to the supply voltage to the motor. Have it checked or check it yourself with a volt meter. Voltage with the motor operating should be with-in 10% of the nameplate of the motor.

Hi, I have an older mobil home with a Colman AC


Your unit uses both the capacitor and a contactor (relay) to start your compressor and motor. With the indications you are giving it would either be the capacitor or the contactor - and since you have already changed the cap - then replace the contractor!

NOTE: We always recommend that you change the capacitor and relay at the same time, because they seem to fail at about the same time.

Outside unit is running but blower in attic is not working line in attic from outside unit is dripping water


You need to get the blower motor going, the unit is froze up. Try switching the fan spped wires on the control board on the unit in the attic.

If that does not work, replace the motor

The outside unit is not working on my Heil Air conditioner


The attic fan is not a part of your a/c system, and you should not run it while you are running the a/c. If you are currently using the attic fan, it is possible that someone wired it so that the a/c won't turn on while the attic fan is on. Otherwise if the thermostat is set below room temp, and says it is calling for cool, then the problem is most likely coming from an issue at the outside unit itself. Make sure to check your fuses, at the fuse panel and outside breaker. Hope this helps

FYI.. the only part of the system that might use batteries is the thermostat.

Ruud AC fan won't shut off


In many mobile homes this scenario is very common, less so in permanent homes, but here is how it works; The heat side of your fan which is the low fan speed is not dependant on the thermostat it's heat activated. Your already aware of this to some degree because you had the limit \fan switch replaced. I've taken that approach to that unit myself. In reality what probably is happening is on hot days your unit is warming up by being hit by sunshine and then it clicks the fan on at 140 degrees. This especially happens if the unit is on the roof or a split system in the attic. Remedies; run your A\C to cool it down, keep your attic cooler by way of an attic exhaust fan(which saves you cash anyway). Or if your not regularly using A\C turn breaker off til you need it. In the end there may be something going on, but odds are I'm dead on. Good Luck

Attic fan motor replacement


It sounds like you are replacing a two speed motor with a single speed. Check the side of the old motor and see if it has high and low speed wiring schematics. If so you need to replace with same model number. Good luck!

Lennox air conditioner is blowing hot air


Check your coils for ice, check your breaker and fuses for condensing unit, and is your condensing fan running? If not, you either have a bad fan motor or capicitor. After you hit the button, and wait for it to time out, (you should hear a click) take a butter knife, and spin the fan if it is not moving. If the fan start spinning by itself after your assistance, you have a bad capacitor
