I have in the past temporarily by-passed the solenoid switch until a replacement could be procured. I was not concerned at all as I knew I could run to the tank and close the valve manually practically just as quickly as turning the remote electrical switch off. I never lost the awareness for the dangers of propane whenever the tank valve was opened, I still manually open the tank valve just before cooking and make sure to turn it off immediately after finishing cooking. I keep my nose and eyes concentrated on the stove while the propane is flowing to quickly respond to a flameout or flareup. When I started boating we kept the propane tank in a cage on top of the cabin with copper tubbing in plain sight entering the cabin to the galley; we had no need for vented lockers, sniffers or pressure switches. At the time I had not heard of thermocouple switches in stoves. Now days I promptly replace solenoids with those that meet ABYC standards for the simple reason that I like to maintain my insurance coverage and would not want to have a claim denied for saving a few bucks. If I had no insurance on the boat perhaps I would keep the by-pass permanently, but that is me. Each has to weigh the necessary safety and convenience these propane systems bring to them.
