Hello,
I was hoping someone could tell me what the Proressiveindustries EMS By-Pass switch is for? Thank You Very Much
Allows you to bypass the EMS in case of a failure. It disables all of the EMS features except for the surge protection allowing AC power into the RV.

Thanks Stuart. I have an issue with my furnace. It works fine at times and then won’t work at times, then works again.
For your furnace issues, it could be a number of things dependent on the symptoms. Such as a faulty sail switch, poor return airflow, or loose wiring on the control board.
If it’s intermittent first thing I would look at is the connections between the board and the thermocouples etc. any place there’s a spade connector etc. I had a loose one on my Airstream which caused similar symptoms.
Could be an air bubble in the gas line, or a faulty propane regulator. A couple less nefarious options to rule out.
