Heater shuts off after 30 sec

[wildbill1195]

Our heater worked fine for several hours after arriving but then quit cycling. If I move the thermostat to off and then back on it fires normally but shuts down in 30 seconds or so. Both bottles are full and stove and water heater works fine. This is in a 2011 shamrock. Any ideas?

Sounds like possibly a thermal switch.

The flame sensor may need adjusting if at anytime it doesn't sense the flame it shuts the gas valve off.

Make sure your battery has a good charge of 12 volts and more........

Thermistor to spark the propane. Mine took a dump as well. Will need to replace.

If it's igniting and blow heat for 30 seconds or so it most likely flame sensor is bad.

I'm on park power. Sounds like the flame sensor, thermal switch or thermistor. Am I correct that this sounds like a job for a pro?
