I just bought a house with a Criterion RGLH-07EAUER down flow furnace. This is our first home, and when we had the inspection the furnace worked just fine. I had noticed that the unit was very dirty though, so I had a technician come over and clean the blower by taking it out of the furnace and service the A/C as well. The A/C works great, but when we tried the heater, it wouldn't work properly. The accumulator blower kicks on, then igniter heats up, gas turns on and flames start. Then a few seconds later I hear a click, the igniter starts to dim and the flame shuts off. I will see 3 quick green light flashes and then it will then cycle once more, but this time when the flame shuts off the blower will kick on and run for a few minutes. The technician told me that I needed a new accumulator motor because the old one was making a loud noise and took a while to get up to speed. I bought a new Rheem 70-24157-03 Inducer Blower Motor 10701 and installed it with no change in the results. I then decided to replace the flame sensor, and this did not help either. I thought maybe polarity was switched so I switched the white and black leads incoming to the unit and no change in results. I saw a similar post about blower leads hooked up to "cool" "heat" and parked leads. I had a red wire coming from the blower motor that is capped off which I found strange, but I doubt the technician would have changed anything that was hooked up because the unit worked before he serviced it. He would have had to strip the wire and cap it off so I assumed it was fine. Black wire runs to "cool" and yellow runs to a "Heat" and blue runs to the "mi" terminal. Any help would be appreciated. We are trying to at least get one winter out of this thing before we need to replace it. Thanks! The people who owned the house before us did not take care of this unit at all. Also, I did replace the filter.

08/29/2016 coleman model DGAA gas furnace questions Hello, I have coleman model DGAA056BDTB gas furnace 7 yrs old. It takes exatly two minutes since I hear it clicking until it runs. After that it works fine without any problem. I decided to replace the hot surface ignitor just to be on the safe side in winters. My flat ignitor is 189 ohm. I don't know if that the original specification or just changed throuh time. It has no number on it. I bought the round Packard nitride ignitor 1G1402N. It is 12 ohm. Does this sound too low and might cause damage? Is two minutes "since I hear it clicking until it runs" a long time? I think it was taking less time before. Last question: the screw and the not holding the ignitor are very rusty, and no listing on them. Can the screw be removed from the burner and install different one? Thanks a lot, I appreciate your help.
