Suburban furnace sf35 test bench, what do I need?

Not bad at all. If all the electrical check out then it might be a plug jet. You'll have to get access to it which more then likely mean the gasket will fall apart on you.


Once you've done it a few times it only takes about 10-15 minutes to go through the furnace on a bench. Just remember you're dealing with something that's hot and needs to be in a well vented area.
