Ok after finding the correct place to call, I got the
newest control board called
"Unity Board"
Guess why?
I bet the control board is also the same
Where is my beer?
I called Dometic Tech service, got a Tech , told him the problem and he gave me the part number "223100502".
Told him the "fatigue" issue he said they normally make a loop with excess cable and wire wrap that loop for
"sail boat" strain relief.
He asked my location for a Distributor near me. Long story, but that Distributor is mad at me since I didn't buy a new Grunert Frig unit for $5200. [I replaced the compressor for $500]
He gave me the Dometic "Big" Distributer in Texas "AER Marine" 800-767-7606
Called them and will get the board on Tuesday, total cost $279 [saved $21, no tax , no shipping]
Jim...
PS: Dometic auto caller and they listed
6 brand names of marine Air systems. Unity is needed.
