Propane help and/or advice

Hello all,

I’m the new owner of a 2016 5.0TA. I received very little in the way of orientation on my new rig. One thing I noticed was someone had cut the wire to the propane alarm. I reconnected it and all has been well except when I turn off the propane tanks. Shortly after turning off the tanks the alarm will sound for several hours and during this time the pressure bleeds off from the propane system all by itself.

If I turn the tanks on and pressurize the system, it stays pressurized and does not leak at all. Doesn’t matter if I use any of the appliances or not there are no leaks and no alarms.

So my question is why when I turn the tanks off does the propane system bleed off pressure and why is it doing so inside the trailer and setting off the alarm.

Of note, I am moving up from a Casita. When I turned off the tanks to that rig it remained pressurized for weeks unless I manually bleed off the pressure.

Thanks to all in advance.

It shouldn't; presumably there's a bad connection or valve somewhere. Perhaps something like a stove control valve only seals properly under pressure.

I think troubleshooting will be a sniffing exercise, either literally or with a gas detector made for this purpose.

I am not familiar with the propane system in an Escape, but I had a sailboat with a propane stove. The oven control had a setting for "OFF" and another setting for "PILOT OFF":. If the pilot light in the oven was out, such as when the tanks were turned off and then back on, and the control was in the OFF position, a small amount of propane bled out and set off the sniffer. Might be your problem??

The oven (if the trailer is equipped with this option) does have a pilot, but if the flame is not burning the flow of propane to the burner will be shut off, because it is monitored with a thermocouple.

I second the idea of a hand held gas leak detector. I picked one up when I replaced the stock cooktop with a Dickinson Marine model in order to check for leaks. They are relatively inexpensive. I think mine was $20.

The Atwood DV20 (2 burner) or DV30 (3 burner) stove that was used for awhile has a little regulator under the cover which can vent propane. Ours smelled around this device regularly. Maybe this is bleeding off gas when propane is shutoff?

Venting propane seems undesirable as normal operation, but venting only when incoming pressure is low definitely sounds bad to me. A good item to check.

Thanks for all the input. I don’t have an oven. I tried the sniffer and I thought it was the stove so I plugged the line going into the stove and still had the same results.

Looks like I must individually plug all the gas appliances and use a process of elimination. I am wondering if the regulator at the tanks may be the culprit, but then could that set off the alarm?

Cutting the alarm wiring reminds me of a time when a friend asked me to change out a circuit breaker in his house. He said it kept tripping because it was weak and not only did he wanted a new breaker but one with a higher amperage rating to make sure it would hold.

I explained to him that the trouble was not the breaker but he had a short and the new breaker would only facilitate burning his house down and possibly killing his family.

Needless to say, I got his attention and we found the short.

On a side note... A common problem with the 5.0TA's and the 21's is the detector goes off from battery off gassing. Many of us have cut one of the wires to get it to stop although it should have been repaired.

This has nothing to do with your issue, it's just an fyi as you are a new owner.

Since the propane tanks are inside with the 5.0 model, I would think the regulator or hoses are the culprit. The gas could be leaking from the compartment inside. On edit, Bob is correct, check the battery compartment vent and the battery water levels.
