Just curious why you replaced the motor as well and not just the Electronic Control Module? Maybe it was running under adverse conditions? I've replaced just the module 100% of the time and never had a call back out of a about a dozen last year. Sometimes you can find a burn on the electronic board that you can confirm the ECM has gone bad. Obviously ohm our your windings, there is documentation from carrier telling you what it should read. Good video man.

Will do, just need to get it out of the truck and get motivated. Had a long day with some pain calls so just reading mail and drinking coffee before I play some world of warcraft and kill things :)

...I did see a guy demonstate in a class I took testing it with a paperclip, 9v battery and a jumper but I don't recall the pin-out :)

Yes and no, they have one that is pretty cheap that you can buy at most supply houses, mine only has an on and off switch on it and you pull the control wires from the module and plug yours in and then hook up two aligator clips on your controller to 24v on the system and you can test it that way. If it works with your controller you know it is a control board issue , if it doesn't then it has to be the motor and/or module.

Nice video. Do you need a special tool to troubleshoot it?

Great video. At $750 a pop, Carrier is making a ton of money. By the way, did you get my private message regarding the colab?
