Question about Heating & Cooling

Open Question

I'm looking for a wiring diagram for an old attic fan motor from GE: Model 5KH3QPA0358

I have a 24" whole house fan with this GE 5KH3QPA0358 motor, but need to figure out how to wire it: This oldGE motor is super quiet 2 speed, single phase, 1/3-1/9 HP, 6.4 / 2.8 AMP, 1725RPM / 1140 RPM. Can anyone help with how to wire it? I need to find out how to wire 3 leads from the 2speed toggle switch to the motor's terminals, one for common, one for high speed, one for low speed. Can anyone help?

SOURCE: wiring diagram

The white wire is nuetral, if you are trying to make a shop fan or something like that then you hook it to the white wire which goes to the wide spade on the outlet. The black one which is the hot and goes to the smaller blade (looking at an outlet in the U.S. on the right hand side) on the plug and should be for one speed operation. The other three should be capped off if you use it this way. If not, then cap off the black on on the motor and run the hot wire on the plug through a three stage switch. To find what speed corresponds to what wire you have to check resistance to the white wire and the lower the resistance, the higher the speed and hook up to switch accordingly. Also, ground the case with a solderless ring connector under a mounting screw attached to the ground prong on plug. Hope this helps.

SOURCE: A/C fan motor burnt; I replaced it, and it will not keep runing very long.

It sounds like you'll probably need a capacitor .......

SOURCE: cant find wireing diagram for carrier 585ejw30050ca

if you have a volt/ohm meter you can unplug all the wires to the valve set the meter to ohms and check to see across each terminal which have measurable resistance these should be the coil, usually the diagram is on the panel door i guess this is not the case so you will probably have to see which wires have voltage when your tstat is calling for heat also you need to make sure there are no other safety holding this circuit out let me know how you make out

SOURCE: RV AC, how to wire fan (blower) motor to capacitor.

You almost have it Look closer at the run capacitor. It has Herm, this is for the compressor, Com or C and F or Fan.

1 of your power wires is the fan speed so connect them accordingly usually black is hi, blue med, & red is low. You are "feeding" voltage to the selector switch on 1 side and coming out to the fan motor speeds.

Next you have a "Common" wire on your fan motor (this means its Common to all the other connections inside the fan motor to me. It is usually white. Connect this to the other line of power usually the Com on the capacitor unless it connects to a strip on the selector switch. But 1 of these 2 places will be the other side of your Power when plugged in. Lastly the brown it is usually the fan capicator only wire and it will connect to the fan "F" terminal on the capicator this terminal will not have any other wires connected to it.

This should make you a happy camper. Please rate me accordingly and good luck.

We have recently purchased an older home, built in 1931. There is a whole house fan in the attic that we would like to get working again. We do not know when the fan was installed or who made it - however,...


What and interesting situation. I have seen installations like what you describe, but not in a residential application. Industrial applications that had very high ceilings and in very old apartment buildings, But not in single family resident. I suspect, that the previous owners "acquired" it through unusual circumstances.

In any event, 1/3 horsepower electric motor is not that hard to find. The real key is getting the right rotation, so the blades will pull the air up and out instead of in and down. Remounting a new motor coupled with the right pulley size for a fan belt ,can control the speed of the fan. Rarely are hold house fans direct drive. Which may be the case with yours, I don't know.

As far as a new 1/3 Hp motor is concerned, I would recommend Grainger Industrial Supply
http://www.grainger.com/Grainger/wwg/start.shtml. They have locations throughout the country and their staff is knowledgeable. They can probably help you with designing a belt & pulley system, to control the speed, if necessary. Keep in mind, 2-speed motors are also available.

Redesigned properly, you can do away with that horrendous shaft.

Hope this helps steer you in the right direction. If nothing else, food for thought.

I have a Trane XE1200 condensor for which I bought a replacement fan motor, same specs as the original G.E. motor. The original G.E. motor was wired to a dual capacitor, which is also wired to the...


OK, locate the terminals on the capacitor marked "HERM"(Compressor lead), "FAN", and "COM".(common)

HERM and COM remian as they are.

The wire going to "FAN" (usually brown) will be placed on either terminal of the new capacitor. (This is the ((usually brown)) wire comming off of the fan motor.) An additional wire needs to be run from the other terminal of the new capacitor to the "COM" on the old capacior.

What you are doing is bypassing the fan side of the old capacitor but still using the compressor side of the old Cap.

The fan should have a wiring diagram on it to help identify the wires if there is no brown wire. The other two wires will be identified on the wiring diagram as well, but one typically goes to the contactor and the other to the board.

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!

Attic fan stops running after one hour


I need to verify you have adaquate air flow, to cool the motor. If you have a window open, and the crawl hole open is there enough air flow into the the attic? It there is enough air flow and it still stops after about an hour, does this unit have a humidistate and a temperature switch on the housing or extension.
If all the switches are working correctly then I could be the motor overloading/heating shutting down and then reseting.

Dayton Attic fan running backwards


First see if the switch has a reverse position. Sometimes you turn the fan assembly in the frame, sometimes you turn the whole frame around. Take the cover off the wiring compartment to see if there are instructions there. Also check on the name plate on the motor, there may be instructions there. Attic fans are usually engineered to blow out.

Need replacement motor for Ventamatic Attic Fan


common motor. get from butler ventamatic or Johnstone Supply if you have an account. Hint, buy a whole new fan for $60; cheaper then buying piece by piece, then you get a new blade,motor and tstat for a little more then motor alone costs.
