Has it been parked level
If not you probably have a vapor lock
DO NOT GO TO A SERVICE CENTER YET
Turn off your fridge for 2 days
Drive around which will allow the ammonia to settle
There are no short cuts... 2 days! drive around
After 48 hours and several differnt trips around the area in your camper... make sure it is level and then turn the fridge back on
Now, you can go to a dealer...who might tell you that they have to do a $1200 fix then the dealer parks it out back, level and off... then drives it around a bit to shake it up!
Good luck
If it doesn't work... you can still change out the board.
