Dometic penguin logic board

[0557]

has anyone on this forum replaced the logic board as the culprit for compressor failure, My compressor will not start, so I used an amp meter to see if it was getting AC to the compressor. I used it in line after the logic board terminal, could the relay be stuck or burned? a 200 part is better than replacing a 700 unit.
thanks for any info on this.

Don't know if this is specific to your issue, but here's a thread on Dometic Logic board replacements.

I just returned from a trip to the Mothership in Jackson Center to resolve my A/C problem. Airstream installed a new logic board - but the A/C compressor would still not kick in. The end result was that we replaced the entire A/C unit - as it appeared that the problem was "loss of coolant." Jackson Center is not equipped to "break in" to the system and there are no "ports" available for testing the coolant pressure. Since this is a "heat pump" unit, the net replacement cost was over $1500, plus labor. The thermostat also had to be replaced since the new units have 5 buttons vs 4 and there is no way to modify the wiring. The only "salvageable" items were the mounting pan and the interior vent assembly. This was a hard pill to swallow for a unit barely five years old! I hope that you have better luck!

I would first check the capacitor. The capacitor gives the boost to start the compressor. This is simple to check and not expensive (a couple of dollars).
If this is it, check with your local A/C supplier and don't hesitate to put in a universal capacitor that he might recommend (been there, done that).
Hope this will help. Good luck.
