Question about Aprilaire 600 Humidifier
When you turn the humidistat all the way up, after a few hours this horrible squeal starts and it wakes us up 2 floor away.
I have seen some humidifiers do this becuase of high water pressure. Try closing and opening the saddle valve and see if it helps at all.

Turn the control knob to the test/reset position untill the change water panel light blinks to reset the change panel timer. Make shure the furnace is running calling for heat.Turn control knob to prior setting after resetting timer. Hope this helps.

if it works in the test mode then it should be okay but you can get a humidity gauge from radio shack and set in the house to see how high or low its is. the humidifier is only going to give a max of 45% humidity

sounds like you may have it wired to a continuous power source vs one that shuts off with the furnace. The most common wiring is red to C & white to W

Put some lubricant, oil, WD40, etc. on shaft of fan. Spin the fan with your finger and work the oil into the shaft until the fan spins freely again. Reassemble and problem will be gone for 2-3 weeks. Repeat again until you want to replace the fan motor.
