HELP! Coleman ST-200 replacement parts or fix?

[Laurie]

Hi!
I have a propane furnace that is missing some parts and can't find much information about how to fix.
This is a Coleman ST-200 and, apparently, the screws that hold the glass in place are stripped. Has anyone else had this problem and how do I fix?

RV repair says I need to replace the whole furnace for over $600 even if the furnace works well.

Thx, Laurie

I'm not familiar with this furnace, but can the holes be drilled out and rethreaded another size. There is a thread repair system that uses an insert called a helicoil also. Or can self tapping screws be used? Some places don't want to do a time consuming repair job, just sell a whole new unit. Bob

Thanks for replying Bob. I'll check into it!

Perhaps you could post some photos. There are a number of ways to repair stripped screw threads.
