My RM60A does not even have a refer light, and no 12V
hookup at all. It's 120V or gas.
The controls are seperate for gas or electric operation, so make sure the electric dial is off and teh gas dial is turned on a bit. My pilot will not light properly if both temp dials are at "0"
It will light up when the gas dial is set to about 4, which makes no sense, but is the way mine behaves.
I woould make sure there is gas going to it, and if not, find out why. Some trailers have individual shutoff valves for all teh appliances. My gas valve partially blocks the 120V plug when on, so it can't be plugged in when on gas.
i am sorry i can't be of more help.
