I am replacing the inducer draft motor on a Lennox

Customer Question

I am replacing the inducer draft motor on a Lennox TGA060B2DH1Y 5-ton 3 PH rooftop unit. The new wiring harness has four wires. The former model has three wires. The part came without a schematic. Would be able to offer assistance in the proper way to wire this? Thank you!

They just approved a charge for $32.00. I thought the amount was supposed to be $18.00?
Customer: replied 10 months ago.
Sorry, my credit card company flagged this as fraud.
Expert:  Tim H. replied 10 months ago.

You requested a phone call and there is an additional charge for that.

Expert:  Tim H. replied 10 months ago.

Did you want to continue without the phone call?

Customer: replied 10 months ago.
please call
Expert:  Tim H. replied 10 months ago.

I can call, but you need to accept phone call request and have your payment clear. I keep getting a message that "customer's payment didn't clear" and then I can't get phone number, etc from you.

Customer: replied 10 months ago.
I do not know why you are receiving that message. May we just continue with written support?
Expert:  Tim H. replied 10 months ago.

You might want to try a different credit card?

Customer: replied 10 months ago.
I only have one credit card. It shows an approval went through for $32.00. Again, may we just proceed with written support?
Expert:  Tim H. replied 10 months ago.

Hmmm, strange. OK, so it looks like they sold you the wrong part. You should have gotten part # ***** This is a 4 wire inducer assembly. CLICK HERE.

Expert:  Tim H. replied 10 months ago.

I was rereading your original question. Are you saying the new inducer assembly came with 3 wires?

Customer: replied 10 months ago.
No. Per my very first message, it is a four-wire harness. The existing has three.
Expert:  Tim H. replied 10 months ago.

OK, hang on a bit. I'm going to check with Lennox tech support. Did you get any extra parts in the kit such as another wiring harness? I also see that it should have come with a relay.

Customer: replied 10 months ago.
No, that is not what I am saying.The original motor has three wires.The new wiring harness has four wires.
Expert:  Tim H. replied 10 months ago.

I understand that. But what I'm asking, is did the new inducer motor assembly come with extra parts? Because I'm thinking there is an instructions sheet that should have come with it involving some changing of the wiring. See here for the motor assembly you apparently have. In the picture it shows a harness and relay. I'm on the phone right now waiting for tech support.

Customer: replied 10 months ago.
the harness came with and as previously stated, the schematic was NOT included. This is where my perplexity comes in. How am I to wire a four-wire harness to and existing three wire? I called our distributor and they pulled the other three motors they have in stock and NONE of them contain instructions either. I was on hold for Lennox tech support yesterday for over an hour and at 4:00 received a message stating the office is now closed and was disconnected. I have now been on hold with them this morning for an hour and a half.
