Hi, I hope everyone had a safe New Years eve. I have a problem with my 1994 18 foot komfort light TT Furnace. I have a suburban SF modle. I got my TT used this summer and it has benn a project. I last had it out on an elk hunt in Nov and the heater was working fine for two days then the problems began. It was cold out and the heater was working hard to keep up. The problem was that it would turn on and blow cold air for some time (20 Min or more) then blow hot air. Then at other times it would turn on and blow hot air like it was fine.

I talked to my brother and he said it sounds like the ignitor, he had a problem with a TT once and it sounds right.

What do you think?

Has anyone replaced one if so was it hard. I am OK wiyth duck tape and super glue so i do not mind tring to fix it my self.

I had luck calling the 800 number of the manufacturer and asking for technical support.

Here is a LINK that may help. If you check your igniter and heat sensor you may find carbon build up on probes near the gas outlet tube in flame chamber clean with a contact cleaner and you maybe good to go. https://irv2.infopop.cc/images/thumb.gif

The last time I had that problem there was three things the tech checked for in addition to the ignitor.
1 - Sail switch, this is located inside the cover for the fan. When the fan gets up to speed it will move and turn the switch on to allow the furnace to ignite.
2- Overheat switch, this is located under the heat exchange. If it gets too hot this switch will turn the furnace off. Can malfunction and cause the furnace not to come on.
3- Computer card, this can go bad and cause intermittent problems with the furnace not comming on.
My problem turned out to be the computer.
