This P-711 Dinosaur Electronics Main Power Control Board is a high-quality replacement lower control board designed for select Dometic Americana gas absorption RV refrigerators. This board is responsible for managing the refrigerator’s propane ignition and power distribution to the AC heating element, ensuring seamless operation whether running on propane or electric power. Unlike some OEM boards, the P-711 requires an external igniter to ignite the propane system. Additionally, it features a Variable Temperature adjustment, allowing users to fine-tune cooling performance for greater efficiency. To enhance reliability, a 5-amp fuse is included, providing extra protection against electrical surges and potential board damage.

Dinosaur Electronics is known for producing high-quality, durable RV circuit boards that meet or exceed OEM standards. With a history rooted in the mainframe computer industry and aerospace research, including work at the NASA Ames Research Center, the company applies rigorous testing and precision engineering to all its products. The P-711 control board maintains all the functionality of original Dometic boards while offering superior performance and reliability.

The board is designed with multiple connection points to integrate seamlessly into compatible refrigerator models. Key connections include P1 (upper control board), P2 (thermistor), P3 (gas valve/igniter), J1 (DC heater), and J2 (interior light and climate control). Additional terminals handle thermocouple connections, AC line voltage, and power distribution to the AC heater. With its advanced temperature control, high-quality construction, and enhanced safety features, the P-711 Dinosaur Electronics Main Power Control Board is an excellent replacement solution for ensuring consistent and reliable performance in Dometic RV refrigerators.
