Dometic RM100 stiff gas valve

The gas/electric selector knob on my '79 Dometic RM100 has always been a bit stiff when turning to gas. It has gotten worse over the years to the point I am concerned I'll break the knob off.

When turning to gas I know it opens the valve on the back of the fridge. Is there a way to lubricate the valve without destroying the seal? What is the best way to do this and the proper lube to use?


Its a camper, therefore it leaks.

Gas valves are generally Metal to Metal spring loaded tapered valves. You should be able to remove the plug of the valve and lube it. Off hand i do not know what to use as the lube so I would contact someone that works with gas and ask.
