How old is this fan motor Uniaire ACD8R1V - Heating & Cooling

Reverse any two power wires, but not the ground.

Try unplugging the fridge, spraying the fan motor with WD-40 -- everywhere you can reach -- then plugging it back in.

this soounnds as though it for a 2 spped fan motor look at the old motor and see the RPM and then look at the new motor plate it shuld show ou which wire is for the speed required. Hope this helps ..Jon

Did you replace the fan blade or the fan motor? If you replaced the fan blade, is it exactly the same blade as the old one? If it has more blades, or wider blades, or if the blades are at a different pitch than the original, it is capable of moving a greater amount of air, but the old fan motor is not big enough in Horsepower to do the extra work. Thus, you should change the blade again to one that is exactly the same as the old one. If it is a window unit, you could try running the fan on a lower speed and it might work.If you replaced the fan motor, you must check to make sure that the new motor is exactly the same as the old one. You also could have it wired wrong, so you must check that also.

old subzeros the CONDENSER FAN MOTOR RUNS OLD THE TIME. SAME WHIT THE EVAPORATOR FAN MOTOR. RUNS ALL THE TIME. now fos systems whit 2 compressor the condenser fan motor run for both compressor. only stop when both compressor stop......

dominion electric might have it if you really have to have that fan but best to get new one same work you got to bring it downand work on it ...less work buy new one less head ache ....

I am assuming you replaced your fan by now. However in the future call Gibraltar Industries, they are the ones who manufacture all fans and motors. My attic motor fan also died and I first called Ventamatic and they wanted $65 for a new motor. I then called Gibraltar and they shipped one our for free. 800-527-1924.

One drop of 30 wt oil at each bearing will quiet the thing for a while, but you will eventually want to replace it. Also consider the whole fan is about the same cost as the motor, and easier to find.

your blower fan screws onto the end shat of the motor. Now the direction? It could be reverse threads. Since you are changing out the motor stick a screw driver in the old motor to lock it up and try righty-lefty to loosen your fan. don't damage the fan with tools.

you have a reversible motor or a two speed motor check the old motor for speed and rotation
