I am wondering if there is a recall or any kind of warranty on a Ducane Model MPGA075B3 Ser# 636608003B.

I am having problems with the Flame rollout switch I have to reset it almost every time my heat kicks on and off. I was told it could have a crack in the heat exchanger. I just moved into the house I have no clue on this furnace on how old or warranties. The Gas man said to check and see if there have been any recalls on this furnace. I am not getting any carbon monoxide but it gets cold in the house when the switch goes.

Your unit has a 25-year limited warranty on heat exchanger, 5-year limited warranty on covered components. Things that can cause the rollout switch to trip, burners not mixing air correctly, gas valve not adjusted properly, heat exchanger blockage, exhaust stack blockage, inducer not coming up to full speed, etc... Best thing might be to have someone come in a check it out for you.

I don't know of any recall.
