Norcold 1200 / 1210 Sr Code (Flame Sensing Malfunction)
The display shows Sr. The power board found a problem in its own flame sensing or gas valve circuits. Norcold’s fix for this code is a new power board.
Before you start
- What sets it. Any of these, in any mode: a problem in the flame sense circuitry; the gas valve being powered when it shouldn’t be; the gas valve not being powered when it should be; or an internal memory fault.
- Fault history. It’s saved about 25 seconds later on diagnostic screen 5, segment 5.
- Not the same as no FL. If the display alternates no and FL, the burner didn’t light, and that has its own checks. See the no FL flowchart.

Does Sr come back?
NO

Solved for now
The code cleared. If Sr returns, the board’s flame sense circuit is failing. Replace the power board.
YES
