Went to turn on the LP generator briefly to use my coffee maker and all the LP systems stopped working. Flame went out on the stove and the furnace stopped blowing warm air and then kicked off. My regulator is a rather new Marshall. The water heater wasn't actively running and there was too much noise to know if the fridge was cycling with the LP or not. I figure under the circumstances of cold temperatures and a high volume draw that either the pressure dropped too low for adequate flow and/or the regulator started to freeze up. So my question is whether this is normal and I need to amend my expectation that I should be able to run all of these systems on a cold morning or should all of this work and I need to further investigate other possible issues? Thank you!
Your regulator , actually the large plastic connector to your LP system has a flow limiter built into it. It is designed to shut down if the flow becomes too great, as in if the line broke it stops the free flow of propane which could be disastrous.
Im guessing you were demanding a large enough volume from the tank that the flow limiter thought it was a broken line and it shut you down.
You can not alter that system so my suggestion is to simply not try and run EVERYTHING at once. This is an RV, not a natural gas system in a residence.
