Norcold 1200LRIM, STARTS/STOPS ?????

Start with the basics (assuming you have a 6212XX Dino Bd)

DO you have 12VDC to fridge....display panel lights work/interior light turns on etc?
NO...check the Fuse that feds 12VDC to fridge terminal block (DC Dist Panel)
Fuse good/12VDC at terminal block then check the DC Fuse on circuit board (5A)

YES.....have 12VDC at fridge/DC Fuse good
AC needs 12VDC to function but uses a 5A Fast Acting fuse. (Some use 8A if they have 2 heater elements)

DO you have any error/fault codes?


Propane lights then goes out
Spark Electrode could be dirty/sooted so clean it using emery cloth/steel wool
Spark GAP 1/8' - 3/16' directly over center of burner slots so it is engulfed in flame when it lights off

Is burner slots free/clear of debris and fully intact (not rusted out/falling apart)?
What does flame look like when it does light.....strong/blue/reaching up into flue opening?

Check to make sure nothing's fouling the flame rod. The flame actually conducts a DC electrical current when everything's working correctly. If a piece of rust falls from the chimney, it will conduct AC electrical current and cause a fault shutting off the gas valve.

My Car engine starts and then stops. According to you, I should replace the complete engine????????? The OP is having a control problem. The fact he has a Dino Board makes the diag more difficult. He needs to contac Dino for troubleshooting help on a Dino board. I would assume a Dino board has different parameters than a OEM Norcold board. Dometic Boards and Dino boards do have different diag parameters. Doug
