We just acquired a 1995 Jayco fiver mainly for the deer lease. The reefer works great on electric, ice cold, but not on gas. It is a norcold 6 cubic foot model. If the reefer is off, as soon as you turn the switch to gas, the check light comes on for an instant, then you hear a click and it goes out. The reefer light stays on like it should be working, but it does not cool down. There is a nice small blue flame in the flue like there should be. We need it to work on gas so we can leave it set up in place with solar power to keep the batteries charged. Any ideas?
