Defrost solenoid
I recently replaced of these. Used a Ranco defrost solenoid which was for another application. The inner metal housing of the solenoid had two metal sleeves that fit inside the coil. They were not equal length. The valve would only function when the long sleeve was in one certain position. I don't remember which way it was; but if the metal sleeves are missing, or in the wrong position it won't work.
