During our "winterization" of the MH, we were almost finished... the last step was to use the water pump to pull some pink anti-freeze into the water lines between the pump and the faucets at the sinks, shower, toilet, etc. In the midst of this, suddenly, the LP alarm erupted... it is very loud. Anyway, nothing was "on"... the fridge is off, the cook-top is off, the heater is off but the LP is on. So I turned the alarm off and started checking around. Then the LP alarm erupted again. I turned it off again. Then, I tested the fridge using ac power, then LP, and it works normally. I tested the heater/furnace and it works normally. I tested the cook-top and it works normally. So I turned the main valve on the LP tank to the off position. The alarm did not trigger again.
After about 30 minutes or so, we had finished the anti-freeze and final "winterization" stuff. So I decided to test the LP system again... I turned the main LP valve on and waited, expecting the LP alarm to trigger again, indicating a leak somewhere (like it did earlier), maybe under the fridge? It never did and has not alarmed again since, even with the LP system "on".
Here's my list of possibilities...
[list type=decimal]
[*]there is a leaky connection in the LP plumbing, somewhere inside the MH, probably near the fridge since that's where the LP alarm is located but maybe
[*]there's a leak in the pipe or joints that goes to the cook-top, which is in the front slide-out...
[*]the fridge solenoid valve did not close completely when we turned it off (weeks ago) and when I cycled the valve, it seated properly and closed... but why did it wait so long to trigger the alarm...?
[*]Same valve story for the water heater solenoid valve or the furnace solenoid valve....although those valves are "outside"...?

Since there was no LP alarm for the next several hours, we resumed our original plan which was to set the furnace thermostat to 39 deg F to keep the MH above freezing (belts and suspenders), so we left the LP "on" and checked it every few hours until about 10pm... no alarms so then we decided it was "OK" for the night. It got pretty cold the next two nights, 5 deg F, and the temperature inside held at about 40 when we checked it in the early morning and during the day. And, there have been no LP alarms.
I could turn the LP "off" entirely and the MH would get really cold but probably be "ok" with all the antifreeze in the lines and traps. I could turn the LP "off" and leave an electric space heater out there set at 39 deg F which might keep the interior above freezing.
The nearest service center is a 3 hour drive from here, BTW.
Help! :-\ :-\ :-\
