I have a 1992 Itasca sunrise 27ft with a suburban furnace . Is this a big fix or small fix . what its doing is you turn it on heats up fan starts blows heat2-3 mins and 5 mins heat stops even though It should stay on as thermostats telling it to stay on all that comes out is cold air. It started this last year . We used electric heater to get by but this year I would like to fix it . Any advise be great . :?

Since you don't give a model number, I can't get you directly to the manual for your model, but click here then scroll down the page to the list of Furnace Service Manuals, continue scrolling to the Suburban manuals and find the one for your model. You can open the manual online or download it (note: files are large). Suburban includes a detailed troubleshooting section in their manuals. I have used it several times with success every time at getting the old heater to run again.

Thanks a bunch . There great manuals. mines SF 20-25-30-35 I have to wait till snow milt to get to it. As sheds a bit full winter storage we had a warm spell and now back to cold . I think its a 30 . It be great to get it working again . It heated great 2 years ago . But mine is 1992 model just so hope its not what i read in the notes. ( if all is clean and burner keeps going out replace control board ) That be nasty but I will check everything else first. :D thanks again and this is a great forum . I will post my findings .
