A170 Inducer motor cycling on/off
Furnace: Heil DC90
Fasco A170 Inducer motor
Symptom: The inducer motor is constantly cycling 5secs on then goes off for about 5 seconds, then repeats this on/off pattern?
Thermostat, Control board, pressure switch, etc.?
I should mention that the furnace will operate fine when called for Heat. The problem is it's cycling the inducer motor continuously, even when no heat is being called for. Basically if the furnace has power it's cycling the motor...
Thanks in advance, great site!Last edited by dk4dk4; 09-22-2010 at 11:25 AM.

Get a life... You all take time to submit non-value answers and probably feel like you achieved something. Same thing you do when you come to a house and try to replace a whole unit instead of the $5.00 part it needed... It's people like you that give your trade the reputation it has today... Keep up the good work!

None of the posters here do that, the site rules say no DIY.

Why do we have those rules? To protect us and to protect you. Some of the work we do can be potentially dangerous, especially the parts associated with a gas burner like what you're working on. We know nothing of your qualifications, so it would be extremely irresponsible for us to give you advice that could put you or your family in harm's way.
Your insult to us was completely uncalled for. There are crooks in most any business, this industry is no exception. But I think you'll find the vast majority of the professional members here to be people of high caliber.
Ease off on the attitude a bit, and the folks here might can be of some assistance to you. But we're not allowed to give DIY instructions.

dk4dk4, hardly a 5 dollar part. the restrictor disc tabs that hold the disc in place on the inducer orifice that meets the collector box costs more than 5 dollars. btw, this model of furnace is usually a nulk, or nugk, and i have seen alot of cracked heat exchangers in the sealed combustion models. this inducer is not cheap at all, and dont forget there is also a smart valve and hsi w pilot to fail as well. good luck and call a PRO for gods sake!
