Dinosaur MICRO P-1338 Rev 5 Dometic Refrigerator Control Board

Dinosaur Electronics MICRO P-1338 Rev. 5 is a replacement control board for selected older Dometic absorption refrigerators. It supports the appropriate AC/DC/LP-gas configurations and can be set up for the original-style gas valve or a compatible newer Dometic gas-valve kit.

Fitment & Compatibility

The manufacturer installation diagram identifies these model groups:

• Early RM models: RM663, RM763 and RM1303
• RM35/36/38 models: RM3500, RM3600 and RM3800

The existing supplier listing also references earlier MICRO P-13 and MICRO P-1338 circuit boards. Confirm the original board, refrigerator wiring, thermostat and gas-valve configuration before treating these references as a direct replacement match.
