You can attach a fan relay wire green and common to the 24 volt, and then your fan speed tap to normally open, and a wire from line 1, and then line 2 or common goes to common of the transformer.

Perfect question.

@@leslieabraham6074 sure, but that means the fan will only work on 1 speed through that relay. The ECM motor can have up to 5 speeds depending on the model.

@@tomtom1541 yeah I think he's looking for a cheaper option. Like the PSC motor.

@@leslieabraham6074 well sure, but he's going to end up spending more money on electricity. So in the long run you haven't saved any money.

So the tool is nothing more than sending 24vac to some specific terminals on the module of the motor that receives 24vac. That is all it does, nothing fancy, it's nothing but a set of jumpers. So most of the time when there's a fault, the 24vac does nothing to get the motor to run and then you're ok to change the module... In your case, you had a bit of an anomaly where the 24vac part of the module was fine, but there's also some communication wiring for controlling the speeds (which is usually through low voltage dc signals and what not)... That particular part of your module seems to be what failed. It's a little unusual, but that would be frustrating since the tool wouldn't recognize that issue. The tool is still far dumber and simplified for what the ecm control does. This is obvious by the fact you're not controlling any speeds of the blower except one fixed speed, yet the furnace board does ramp it up and down and has almost endless speeds.

I’ve had this same issue twice recently. Each time motor ran with tester, ended up being faulty modules for specific taps for cooling.

Hey Jeff. Did you get an answer to this question? Do you need to get an Eon drop in replacement motor programmed?

@@jamesdaws3457 Regal Beloit was hesitant to even talk to a DIYer about it. Nor could I get a straight answer from any forum. I eventually bought a reconditioned one from www.ebay.com/usr/unitedhvacmotors. It works fine. I had to switch a couple wires in the harness since my motor turned the opposite way. But they had instructions for that.

@@jeff3741 Thanks Jeff. We're you able to get one with the same model number or did one work with a different model number? I suspect the myriad of model numbers and programming codes are mostly a smoke screen.

@@jamesdaws3457 I contacted the seller and told them what I had. They sent me the one that worked. I think the programming is based on the multiple speeds the fan runs. The RPMs for slow and fast are different for the various models. I tried an unprogrammed motor first and it didn't work at all. That's when I went with the e-bay seller.

Ive used this tool on a 16 pin trane variable speed. It ran great on full speed with the tool so I replaced the board and the motor still ran at like 100cfm lol.

Its a trend. I can understand how many people will quote $100 to $200 million or 3 to 5 years etc. Tells you very little except that they have no idea.

just a piss poor design.. designed to fail.. planned obsolescence.. should be a class action lawsuit.
