Christy, Just saw this was Post Number One. WELCOME! Hope we can help you and you'll hang around to help others.
Thanks for posting Make/Model. Many do not and it really becomes a guessing game.
Our friend and mentor Chris Bryant (RV Shop Owner) has a lot of manuals on his website. I picked
this one because I couldn't find your model number and this one was close to it. Your problem sounds somewhat like "thermocouple" in the troubleshooting but the ones I've seen do that will burn a few seconds after lighting and sparking stops. The it'll do a "re-start" since the thermostat is still calling for cooling, and repeat the cycle. If you DO replace the thermocouple that "wrench" fitting is NOT LP Gas. It's only an electrical connector so don't overtighten. But that's just a warning for futures, we aren't anywhere near that far along yet.
Robt, the manual I referenced says "thermocouple" and not "flame sensor, flame prover" etc. I don't fully understand the "sensor" but I do know that a failed thermocouple will let the gas valve flop shut once the logic board's power is removed from it after the startup cycle. Christy should be hearing a CLUNK when the flame goes out since the Valve isn't getting the voltage from the TC that it needs to stay open.
Chris, Does one of your online service manuals cover Christy's model RM2351? If so which one...
