Comments about RPC Circuit Board for Whole House Powered Humidifiers:

Bryant humidifier was tripping circuits, so believed circuit board was at fault. Replaced board, but found actual culprit was a short in the the solenoid. Ended up having to replace both. iaqsource was very responsive in filling orders.

Comments about RPC Circuit Board for Whole House Powered Humidifiers:

This circuit board is a universal replacement for many whole-house power humidifiers. Most humdifiers are made by the same manufacturer.

Label all the wires before removing them from the original circuit board. I reversed the polarity on the 2 humidstat wires and on the 2 wires for the solenoid; it wouldn't work. Good news is that this didn't destroy the circuit board and once corrected, everything worked great.
