I have had nothing but trouble from this fridge since new 5 years ago. in the last 8 months I have had a completely new control board and thermostat. running well since on electric and gas. Turned fridge on ready for a trip yesterday and error code 18 and a flashing diplay appears. book says contact thetford, the gas is trying to light all the time, anyone else had this prob, I'm hoping to find the paperwork to the repair, if its the board again. not happy.
