LP Gas

Stutchy

The LP tank is full, the valve is open but gas is not flowing. Neither the cooktop burners or the Alde heating system work. The Alde control panel states "Gas Failure."

Some folks with more knowledge than me will likely chime in, but what I'd do is turn off every gas appliance, turn of the propane at the tank, then disconnect the propane hose from the tank.  Next, reconnect the hose and make sure it's good and seeded/connected.  Turn on gas at propane tank, then try the stove to see if it's running.  

I know from propane tanks and burners/grills, sometimes you can get some type of air lock if you turn on the grill before turning on the tank-- and it helps to reset everything.

Sometimes the regulator will trip if you turn the propane valve on too quickly.

What year is the trailer?  The propane "pigtail" that comes from the tank to the regulator has a small valve in it that will shut off the gas supply in the case of a leak.  This pigtail, since it is mechanical, can easily fail over time.  Propane regulators can fail, also.  Depending on the year of the trailer, it might be time to replace either of these devices.  And, judging by the info that nothing is working, I'd start with the pigtail.

There can be other variables: elevation changes, etc.

2019 T@B 320. I recently replaced the pigtail. Is it difficult to replace the regulator?

And, not sure what it means to have the regulator "trip."And, can I do anything about that without replacing the regulator?

"Trip" as in not allowing propane to flow.  I read this in another post.  Simply open the tank valve very slowly.  Mine's a 2016, and I had to replace the regulator a few years ago.  Very simple swap.

Before you open the valve slowly, open a stove valve briefly to depressurize the propane lines.
