Dinosaur Electric MICRO P-711 Refrigerator Power Supply Circuit Board - For Dometic 293 Boards

Restore your Dometic RV refrigerator to reliable operation with the Dinosaur Electronics MICRO P-711 Refrigerator Power Supply Circuit Board. This high-quality aftermarket replacement board takes the place of the Dometic 293 series board and is engineered specifically for the demanding electrical environment of RVs — adding protection and reliability features the original board doesn't have.

A Smarter Replacement, Not Just a Like-for-Like

Dinosaur Electronics is dedicated to making the highest quality RV replacement circuit boards available today. The MICRO P-711 isn't just a clone of the original — it adds genuine improvements that address the well-known weak points of the OEM board:

• Built-in surge protection protects against installation errors and dirty RV power supplies
• Fuse-protected 120V AC circuit, 12V DC supply, and DC element
• Improved thermocouple circuit eliminates the recurring check-light problem common with the original board
• Built-in microcontroller for highly reliable operation
• Easy-to-remove protective cover included

Food Saver Feature

One standout feature: the Food Saver function keeps your refrigerator operating even if the eyebrow board or communication link fails. Instead of losing a fridge full of food while you wait on parts, the unit keeps running — a real-world feature that pays for itself the first time it saves a load of groceries on the road.

Built-In Temperature Control for "Dumb Eyebrow" Fridges

For the fixed-temperature Americana and Freedom Series refrigerators with a "dumb eyebrow" panel, the MICRO P-711 adds built-in temperature adjustment — a capability the original board doesn't offer. That gives you real control over your fridge temperature rather than living with a single factory setpoint.

Compatibility

The MICRO P-711 is designed to replace the Dometic 293 board in the following refrigerator models:

• NDR1062, NDR1272, NDR1282
• S1521, S1531, S1621, S1631, S1821, S1831
