At 2 AM this weekend at a tail-gating camp-out the temperature was plummeting towards 32. The CO/LP gas alarm came on and would not let the heaters come on or the fridge to run on propane. The sensor controls a valve on the propane tank. When the propane heaters come on, there is some propane leakage until the gas is lit. I had to jumper it out or freeze.
Upon taking the sensor out in my hand, it had a date stamped on the rear and on the front it said replace by June 2015. Upon looking up to buy a new one, I find it has a 5-year life.
