Hello everyone, i'm in need of some help. I took my furnace
apart in behind the thermostat adustment knob, and i was foolish by not taking a picture of it before i started. My furnace
is a 76 model year suburban furnace
that is in my boler
. It is the auto thermostat model. In behind the white knob i have a copper coil with the copper sensor , a big spring, a black rubber diaphram, then another small spring, a small metal with rubber backing pluger, a round flat metal ring with ciurcular cutout, and another metal plunger. I know this isn't much help. I'm really hoping one of you has a parts diagram or has taken their furnace apart before. Please help if you can.
