I have a commercial freezer that is not kicking on. When opening the cabinet, I found a fan that had come off the shaft and had wedged into the motor. I re-installed the fan. The unit still did not respond. I checked capacitors and found one bad, replaced. Still no kick on. When power is applied, 240, slight tick from defrost control board. when I manually push in contacts, compressor and fans kick on. I checked voltage going to contact solenoid and it had voltage, 22vac. Ohms were 1.757 disconnected. I am guessing that the solenoid is bad on contacts. How did I * Contact is Furnas 45CG20AG. Thanks guys

Good,just be sure that the control voltage to the contactor is supposed to be 24vac and not 110vac./240vac.

you can tell by reading the coil voltage on the existing contactor...

hope this helps...keep up the good work!
