Help wiring motor to kickspace heater

acurrier · 02-15-2009, 07:51 PM

I am replacing an Embassy Industries HAV-88 kickspace heater motor and blower. When I removed the defunct blower/motor, there were two wires coming from the motor to the electrical box. I just got the replacement, and there are now 3 wires, but I still only have 2 wires in the electrical box. I tried to find some specs from the manufacturer A.O. Smith but I have been unable to find anything so far. Does anyone know what these three wires (red, black, white) are for? I assume two powers and a ground but not sure. The website below has all the information:

Thanks in advance.

Can't find that motor in the link provided. Is it a 2 speed motor where the old one was one speed?

it's .57 amps not 57 amps.

Thanks for the amperage clarification. Maybe I didn't see the decimal on the case. The photos are there, not sure why you're not able to see them. Here are the direct links:

The motor I ordered should be the same one as the one I replaced. I had it special ordered and was told it was the motor for an HAV-88.

looks like a two speed to me.... test it and see.

The photos are there. I see them. The link provided to A.O.Smith does not have info for that model of motor. Did any paperwork come with the motor? I am thinking this could be a two speed motor and the old one was one speed.

White to black one speed.
White to red second speed.

Thanks for the responses. I cannot find this exact model on the A.O. website anywhere due to their poor search capabilities. So it sounds like I have a two speed motor. Dangermouse: how do I test it? Joed: can I just ignore one of the wires and hook it up to the box?

There are 3 wires on the motor, black, red, and white. There are two wires in the electrical box, both black. Which goes to which?

You'll need to test those blacks to see which one is hot. Connect the hot to black or red, depending which speed you want (low speed is 60 cfm, high speed is 103 cfm) and the other to white.

Do you have just an on/off or high/low/off switch?

You're old one was apparently single speed and that's why you're short a wire.

Thanks for the info wirenut. The model I have just hooks up and turns on when the heat turns on - there's no switches. This is an old model that was put in when the house was built (I'm guessing) in 1988. Newer versions of this type of heater do have a hi/lo switch, so even though I was told this was for the HAV-88, it appears I got one for the HAV-88-2.

I will test the blacks and find the hot one. Does it matter which speed? I guess low would do the trick. Which color is low, and which is high - can you tell? And what do I do with the "extra" one - just let it sit?

acurrier · 02-16-2009, 09:00 AM

According to an electrician friend of my father's, the hot wire is white, low speed is red, high speed is black. If anyone thinks otherwise, please let me know. I will be doing some trial and error this afternoon. Thanks for the responses.

DangerMouse · 02-16-2009, 09:11 AM

there is a specs pdf on your link at the bottom. have you looked at that? it should answer the question for you.
my crappy pdf reader didn't open it, thanks again, adobe, for another 'new' format....
i should think white is white and r/b are hot, black-high speed, red-low, but maybe i'm thinking bassackwards again?

It's a 120 volt motor so the white would be the neutral and red/black would be hots, depending on the speed.

Hook up the red and white, turn it on and make note of the speed, then disconnect the red and hook the black up and make note of the speed. You'll be able to tell which one was low/high. Yes just cap the one you don't use. Since it has an insulated spade connector, you could just put some tape over it.

tnkx wirenut! i thought so, but my coffee level is still low.....

He may be thinking that this is a switch box using a 3 wire cable where the switch would be fed with the white and black/red are switch legs.

This isn't the case.
