Humidifer Replacement Circuit Board (Honeywell)


Inspect the mylar wrap on the windings for discoloration or melting (from over heating). Inspect the diodes and traces for burn-outs. To test this board we apply 120 vac to the terminals labeled LINE VOLTAGE.
The humidistat (connects to E5-E6) is simply a switch that opens and closes.
Thus to test, touch the yellow wires that connect to E5-E6 together.
You should then hear the relay click.
The solenoid and fan would then get power.

The diodes rectify the voltage to DC that is used to drive the on-board relay. Connecting the yellow wires (E5-E6) together routes the 24 vac to dioides, producing the DC voltage that closes the relay contacts. If the diodes or relay have failed, then the 24 vac at E3-E4 would be present when the yellow wires are unconnected. But the relay would not click closed when the yellow wires are connected.
