Question about Aprilaire 550 Humidifier
Check and make sure the voltage is the correct - Usually 24 volts.
Almost every time one of these went out on me the wires were touching some part of the metal, or pinched somewhere. The easiest way to fix that is use a temporary wire and hook it up. Make sure you double check the voltage though. If you have a meter and know how to use it check for continuity between the wires for the humidifier
