need info

[boxcar]

Hello and thanks for your'e time. I can't find info I need on the internet concerning problems with my furnace.It is a Frasier Johnson model #FG8B07S12. I am looking for the limit switch rating ( the present one is OEM 160. ). I am also wondering if the installation in a crawl space requires a left or right side only installation, it is on it's left side now. I have had several contractors out who have replaced everything plus redoing the return air ducting directly into the plenum to increase air flow. I could have bought a new furnace by now. The limit switch has been bypassed this whole time to keep it running. I'm nearing the end of the rope so any help would be greatly appreciated.Thanks again.

You are in some very dangerous territory. By-passing the limit is one of the most dangerous things you can do. Shut it off, and find a REPUTABLE contractor who can DIAGNOSE the problem, instead of just throwing parts at it.

We had a local dealer bypass a limit a few years ago. Not much left of the house the next day :(
