RE: 1995 192TB refridgerator
Greetings,
I also have a 192TB ('96 Dodge). I assume yours is a Coach House. What chassis are you on ?
My Dometic fridge has the little clear plastic square at the left front of the unit at the bottom.
It has to be somewhat shaded in the unit to be able to see the light. I usually cup my hand over it.
Does your fridge work ok? Mine doesn't get cold enough. I've removed it, turned it over, shaken it etc. etc.
Seems to work best on AC.
Anyway, good luck.
