how can you just test the control module by itself (not connected to anything)?
The position of the plugs in a motor I troubleshoot Friday was up.
I have a ac fan that wont turn off and the hvac tech says it a bad motor. Have you ever seen this happen. I could possible see it being the motor control but wouldnt think it would be a motor going bad. Looks like my part number is a 6205E.
There’s a video that kind of describes that problem
The video is called “ECM multi speed blower motor trouble shooting” by AC service tech LLC. On RUclips he explains the similar problem. Hope this helps
If it's the blower motor, then the relay in the ECM control module is bad.
I have watched 2 dozen videos on the ECM motor and controls and nobody ever goes into detail about what component of control failed and how to figure that out. 2 things happen with controls. They either will not run or will not shut off. I'd like someone to explain what on control board would cause either of those.
My failure mode is a little different. The motor just jiggles back and forth a number of times, never actually starting, and then just gives up.
@@kf3en I have this same situation. Did you confirm that the control module was bad and the motor good?
@@rakembuzz Yes, motor was good, control module was bad, but you get both when you buy the spare motor, so I swapped the entire unit. You can ohm out the windings on the motor to determine if it is still good. (95% of the time I would guess the motor is good, especially, if it ohms out and still spins ok. It is common knowledge on the web here that the control modules go out often and are susceptible to surges on you line. Be advised that you may need to buy a fan puller tool to get the blower fan off of the motor shaft. (amazon)
@@kf3en it's planned obsolescene.. ploy to screw every homeowner with a 15 yr old furnace.. Should be a class action lawsuit against these scum bags.
these motors don't last longer.
Another Rexnord ecm module fails.....time to move on....no surprise here.j
class action suit I should think.. Planned obsolescence ploy to sell a new furnace when the rest of the unit is just fine and would work another 15 years if that steaming GE ECM pile didn't have the electronics near a friggin heat source. They should have the crap sued out of them.. Just disgusting.
@@dwayneflint8332exactly.
"infinity"... "infinity"??? you have a meter that measures "infinity"??...
Mine does
