No heater or stove operstion

[bsamot69]

2018 keystone Bullet by Colt (171RKCT) heater stopped heating suddenly. Used heater day before no problem then turned on and see igniter works but no ignition. Changed propane tank with same result. Then tried to see if stove worked and there is no gas getting to appliances. Stopped there,.what can I check / do to get things working? Any quirks with system in these trailers?

If you ran out of lp gas and changed tank over manually (turned valve on regulator to full tank) three things come to mind.
First - air in the line. Turn all burners on stove top on and wait a min. or so. You should hear and smell gas. If gas is not present then
Secondly - turn gas valve off and all gas appliances off. Then open tank valve SLOWLY. If you open the valve too rapidly the valve can "see" that as a leak and shut it's self off. Repeat first operation. If still no gas then
Third - change hoses on tanks. If regulator is bad the gas line to the regulator that was working should still work,.

As flybouy said, there are multiple "safety valves" in your propane system. First, there is a "volume valve in the tank. If you open the tank valve when the tank is not connected to anything, it will not flow propane. That valve senses "excess flow" and shuts down that flow if it reaches a certain volume. Just turning the handle on rapidly will allow flow into the supply hose sufficient to "shut down the safety valve in the tank".

Next is the excess flow valve in the supply hose. Yes, there's a valve in that short black rubber hose that works just like the one in the tank, so turning on the tank fast may not activate the tank valve, but it may activate the hose valve. Same result, no propane flow to the regulator.

Next is the regulator, and again, yes, there is an excess flow safety valve in the regulator as well. Same function, same result...

So, if you have no propane flow, turn everything off, open a stove burner valve to allow pressure to dissipate, then turn the stove burner back to off. Go outside and SLOWLY open the valve on the full propane tank. You should hear a click and a hiss as propane flows into the hose and to the regulator. Go back inside and try to light a stove burner. It may take a minute or so to purge all the air out of the lines. Once the burner lights, try to relight the furnace. It should work, if not, turn the thermostat off then back on and try again.

If all that fails, go back outside, put the full propane tank on the "other supply hose (you may have a bad supply hose valve that won't open) and try again.

Good Luck.
