Problem for Honeywell Power Humidifier: Furnace Humidifier/ Humidifier
Replace Honeywell IFC board? - no power to igniter
By Putty - usenet poster
replace Honeywell IFC board? - no power to igniter
12 year old Rudd Deluxe 90 Plus gas furnace at my home won't ignite.
Induced draft motor keeps running. No power to igniter no matter how
long I let furnace run. I traced the problem to the white wire into
the igniter. It's not providing the power or ground to the igniter.
The ignitor's black and white wires plug into the IFC circuit board.
Troubleshooting guide says to make sure vent is open (it is), then to
make sure air proving switch is working and is closed (I don't know
where it is or how to test it), and then to replace IFC. Should I just
go ahead and replace IFC? This will be the second time I've replaced
the IFC board. Is that typical? I would appreciate advice on where to
buy the IFC board - Honeywell MPLS MN55422. How much should it cost?
I'm in metro Detroit, Michigan area. Thanks for your advice. Michael

Typical.
Could be a few things...
Stop now..call a tech..
And if its a $4 part thats actually bad???
Very
You cant. Rheem will not sell to a homeowner...at least not here.
Also, if the board isnt the problem, you can forget returning it.
Also, the new board looks nothing like the old one, requires a couple of
rewires, and cant be returned.
Dunno what the average labor rate is in your area, but around here, expect
between $175 to 290, depending on the dealer.

Thanks for the advice CBHvac. I got one web price of $220 for the IFC
board. I'm going to call the same furnace tech that installed my
furnace about 10 years ago. He gave me the second board for a much
lower price about four years ago, when my first board went. It was
used stock, but worked. I replaced it myself and that got the furnace
working again. This time, the furnace quit working after I replaced
the Spaceguard pleated air filter. I let the furnace run a day
without the filter (the old one was dirty, and I went to buy a new
one), but don't see how that would affect the furnace. Is it just
coincidence that the furnace quit working when I worked on the filter?
I didn't open either furnace panel before it quit working. Both
lights on the IFC are on. Thanks. Michael
