Re: Fan Literally came of AC unit! Please help
Maybe. Shut of power to outsde unit. Remove screws holding the wire shield on top in place. You may need to unhook wires to motor. may or right down where they came from. Turn top upside down after removing fan blade from bottom. Check and make sure blade didn't puncture coil. if the hub is still attached to blade you should be able to slide it back on shaft. try to get it back where screw marked shaft and tighten it back in place . some times it it hard to get screw tight if it is on the motor side but you need it tight. Some times a 1/4 inch extentsion turned backward works . Put a wrench on socket end. If hub is broke off you will need a new blade. Becareful not to bend blade as this will cause it to shake when it runs. If this motor was replace recently the company should fix it for free as it was no tightened correctly.

First of all check your fuses for the blower fan. If this seems alright, then check on the fan control switch. if not remove and see if the rheostat is faulty. loop to confirm or if not you will need to remove the blower unit for confirmation of the axial fan. Try and check one by one to get to the fault finally before you pull out the entire unit. hope you try this out.Good day
Hi, I want you to try a couple of things for me if you will. Go to the thermostat and remove the cover. Now if you have a small bladed screw driver, loosen all the screw on this next section and remove it. Turn off power to the unit, if it is a split system, turn off the indoor unit. Once you remove this section which is the thermostat you will see the subbase and wiring. Take the red wire loose and off of the terminal. You may have a red jumper wire going from RH to RC. Remove the red wire coming into the stat at either point. Give it a minute and see if the fan stops now. If it does, you will need to replace the stat. If not, depending on the age of your unit, if your high limit/fan control tripped, that will be the problem. Some units have a fan control combination high limit that trips causing the fan to run all the time. You need to take a look at your heater section at the front of it to see what kind you have. If it is a combination fan/limit. it will be inserted into the fire box. It is square looking box with a cover on it some with a auto/ manual button on them Sometimes the contats will stick causing the fan to run. They can be removed with power off and cleaned up. They will have a dial with a temperature reading on them which tells the fan to come on when it reaches this set-point and off when it cools down. It may have stuck closed. Check what I have told you with the stat, and this and let me know the age of heater and if it is a split system Trane with a remote condenser and furnace located somewhere else. Get back to me on this. Shastalaker7
Souns like the compressor is running but the cooing fan is not. First you should see if the fan is blocked . Then see If the fan motor is getting power. If the motor is getting power it could be that the motor is bad. If the motor needs a capacitor to start that could also be the problem. Look for a cylinder shaped protrusion on the side of the motor. If these all check out then whatever tells the fan motor to come on is not working. Sorry but I cant help with that. Good luck!!
unless you have a meter youneed to see if the unit is asking the fan to turn on. if so the fan (which i doubt) maybe gone bad or the starting capasitor for the fan... is there anyway of checking the voltage to the fan
Most likely a bad motor or bad capacitor. I would check the capacitor first as this is probably a $20 fix. The fact that it runs in the correct direction but at a reduced speed really leans hard to the capacitor.
Good Luck and hope this resolves things for you. Let me know.
hi! there, continous fan motor when unit was shutt off,since supply source was already cut off specially on fan condenser motor,the supply of your motor was came from relay mounted on your circuit board control panel,there a holding coil to hold the connection between your fan and ac source,shut off breaker for ac unit first before diagnosing ac unit, try to check this out the relay is still activated giving ac source when shut off,the contactor on relay holding your ac supply was shorted,try to check the connection the circuit activating condenser fan relay,eliminate the short circuit,using multi tester test rod,use manual diagram for circuit control board to lessen complicated diagnosing,focus on fan relay ac source then isolate checking the short circuit replace defective relay,contact point of relay are not repairable.take necessary precaution on checking to avoid shock,this a hard task i would suggest that certified ac technician w/ full knowledge of instrumentation should do this.thank's for selecting fixya and have a nice day.
