I looked at a Carrier furnace (model 58sxBo8o-131GG). The inducer motor starts and the furnace fires but trips the limit switch due to the blower not starting.
The owner stated that the motor & module were replaced two years ago.Its a G.E. module ( cno201ak6 ). I have 120 volts at the four pin harness.Also have voltage on the 16 pin harness.
Is there an easy way to check this type of motor & module? The owner does not have manuals. thank you
P.S. The motor turns freely and the module circuit board is not burnt or melted.
FISH ON!!

Acording to the information I have the 58Sx has just a standard 120 vac blower.
Xenos.
The best way to escape a problem is to solve it.

This is not a standard 120v blower. Furnace is 15 years old.
Have you worked with ECM Motors. This is my first. Just looking for more info.Do you know of a tech support # for carrier? Thank you

May not be the exact model but the guts are all the same.
