I have a Miller( by Nordyne) Induced draft residential gas furnace(90 %) Model # G5RC080C-16 80,000 btu. It will run until stat. is satisfied, then when stat. calls for heat it tries to cycle several times with out success, the inducer motor keeps running and I get a one flash error code( problem in control circuit).I replaced the limit switch located on the inducer housing 2 years ago, and it's ran fine until a couple months ago.I checked that limit and all the other ones on the unit and they are working. Any info would be greatly appreciated!
