Pentair pool heater inducer motor issue

End of last season, I replaced the “squirrel cage” wheel on inducer motor. Tested, worked like a charm. Winterized pool. Covered heater from elements.
Opened the pool, tested heater. Thermostat and flow / pressure sensors OK on display. Inducer motor did not come on. In fact, it only heated up. I took the whole assembly out, hooked the motor to wall 110V, and it ran beautifully.

Also inspected the covered area / ?power block where on/off switch is, and all wires looks good.

Any idea what could be going on???

thanks

Did the inducer motor work when you re-installed it?

What heated up.... the inducer motor ?

If it ran when you removed it and connected it to 120v but not when reinstalled.....
it's one of two problems.... the blower is hitting or there is not 120vAC being supplied to the motor.

You said you had the motor running when you connected it to power outside the heater. So, you know the motor is good. Did it run when you tried re-installing it in the heater? If it doesn't run when you put it back into the heater that narrows it down a lot. Is it getting power from the heater? When installed does the motor turn freely?
