Common Failure Symptoms Solved by SF-RV-114

Technicians and property owners typically replace 91447 when experiencing one or more of the following failure modes:

  • Spark is present at the burner but the gas valve never opens and the DSI light comes on
  • Water gets hot on electric but not on gas
  • Water heater shuts off on gas well before the tank is hot, or the water comes out scalding

Step-by-Step Dimensional Verification & Installation Notes

Turn off the DSI switch and LP supply. With the water cool, the 91447 should show continuity across its terminals; open when cold means it has failed. Also check the 93866 thermal cutoff, which is a separate part and does not reset. Pull the wires off the 91447, remove its mounting screws on the front of the tank, and seat the new control flat against the tank so it reads water temperature correctly.
