I have the same problem!

This posted question is exactly one year old, but I just got this solenoid valve assy from ontimemall in Phoenix AZ. I don't have the receipt right here, but it was about $90. It is classified as: honeywell 32001639-002 solenoid valve.

Normal operation should require both the fan to be running and for the furnace to be heating before the humidifier will run. Check out the manual here: https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-2413EF.pdf

I have the same problem and I have 2 of them fairly new. I can't seem to find out what the problem is either.

Stumped?????????

Check the thermo protector fuse at the bottom near the heating pad. The fuse must not be open circuit. If it is, replace it. You can order the fuse for $1 from eBay or Amazon. Good luck!

The motor is the only thing that can cause the noise, best to just replace it.

Same thing is happening to me this season - and it's none of the above - it's the darn pump. The HUT220s have been perfect for 2 seasons, but this year, the pumps rattle and growl no matter what I try, and one won't pump water at all. I had to call Kaz/Honeywell for replacement pumps. 1-800-477-0457. Oh yeah, and he's sending them NO CHARGE!It took "Bill" a while, but he found some for me. Honeywell inventory system says there are none in stock, so if you call and someone tells you they are out of stock, MAKE THEM CHECK WITH THEIR SUPERVISOR - THEY ARE THERE SOMEWHERE! They probably list them under the new model number for this year "220W" but the whole 200 series uses the same pumps based on all the photos/diagrams you can see online.I looked all over online for them to see if I could find them sooner than the 3-4 weeks it will take to deliver them, but there are none to be found. If anyone knows a place that delivers to Toronto, Ontario, Canada, let me know!

I wouldn't mess around with trying to fix it myself if the item is still under warranty. If you are smelling burning, and safety mechanisms aren't working, I'd be very careful about continuing to use it. Do you still have your invoice? At only 2 months old, the unit shouldn't be malfunctioning like that. Best thing to do would be to take it back and exchange it for a new one. If the place you bought it from won't take it back, then call Honeywell directly. Honeywell should cover either fixing it or exchanging it under warranty.
