Found a very small propane leak in the solenoid/valve on one of my Atwood 8500-IV furnaces. The leak is coming out the burner-tube section but nowhere else, so I'm pretty sure it's a failed diaphragm.
I can see (and sniff propane at) the valve assembly but no way to get just the valve out by itself. Do I have to remove the entire furnace including frame, or can the insides (motor, valve, burner, etc) come out leaving the frame & ducting in the coach?
The service info isn't clear, and I'd prefer not to disassemble the entire thing only to find it's held in with 2 screws or something
