    I never said it was broke. I was wondering if it is energy efficient and how much better would a new one be.

Is this your main heating system for the mobile home? I hope these other solutions mentioned help but I would think you have to replace it since it is a 1997. Mobile homes get cold I wouldn't trust it if it does it again.

SOURCE: Colman Furnace keeps kicking on & off

Denise, my heater not a coleman (a monitor heater (oil) kept turning off when the temp got really cold. I would advise you to ask if you can do this, I addded an additive to my drum outside which holds the fuel. Because the deisel thickens up when it gets cold, which makes the heater have a harder time distributing the fuel to the heater. So far the heater has not kicked off.

Model DGAA070BDT SER# 0112o6717 Colman Mobil home furnace My furnace makes a internal thump when it's in the cool down cycle after the burner shuts down and only the fan is running before the furnace...


Coleman is known for this. I have seen many over the years make this noise during cool down. The heat exchanger is contracting and expanding. The heat exchanger is the part that the fire burns in. It surrounds the flame, and when the furnace is on, the metal they use for many of their furnaces has a tendency to make noise as it cools off.
One other thing, if you don't already have one, it would be good for you to buy a carbon monoxide detector and put it in the mobile home somewhere up high hopefully in the hallway close to the furnace return air. If the heat ex. is expanding as is sounds, it would be good to make sure it does not have a crack in it , in turn releasing dangerous fumes. Hope this helps.
