I have a Model 7970-656/D Coleman-Evcon gas heater, it has worked fine for the last few years, now when the thermostsat is turned up the fan goes on but the furnace doesn't fire up. I'm having a hard time finding the right parts ( no model #'s ) to see if it might be the HSI. Any help?

You will need the unit model number to get parts unless you can post the pictures of the parts and then you might get lucky.

This spot has parts and can be of assistance when you post
