Water does not get to Humidifier. Goes from source to motor.
That is not a 'motor' on the side of the humidifier housing, it is a solenoid valve. The water feeds in to one side and exits the other side to a tube that feeds in to the top of the humidifier unit. The valve opens and allows water to flow when electrical power is applied to the valve
The valve electircal requirement may be either 120 vac or 24 vac. Power typically is switched on and off by a Humidistat control. The power feed to the Humidistat may come from a small transformer if the valve is a 24 vac unit, or directly from a furnace connection if the valve is a 120 vac unit. There are many variations, though.
A qualified licensed eletrician should check the power feed to the valve. If there is no power feed to the valve then he can trace back to the point of failure and correct the issue ... but he must also check for additional issues with the valve itself, as noted below.
Other possibles reasons for solenoid valve failure:
If power feed to the valve tests ok, then the coil inside the solenoid may be 'open' (bad, no continuity). The electrician can test the coil by checking resistance or continuity of the coil.
A non-electrical problem is that the valve path may be blocked by hardwater mineral build-up or other foreign material that flowed through the water line.
The solenoid valve must be replaced if either of the above is true with your valve.
Remember, use only a quailified licensed electrician!
