The Dinosaur Electronics P-246PLUS is a direct-replacement control board engineered for Dometic old-style and new-style gas valve refrigerators. Loaded with built-in protection features -- circuit breaker, reverse-polarity diode, and AC fuse coverage -- this board delivers reliable 3-way operation and real safeguards that the original equipment often lacked. A smart, confidence-building upgrade for anyone troubleshooting a dead or failing Dometic fridge board.
When a Dometic refrigerator stops cooling or fails to light on gas, the control board is one of the first components to suspect. The Dinosaur P-246PLUS is purpose-built to replace the original board in a wide range of Dometic RM-series units -- covering both older and current gas valve styles -- without requiring wiring modifications.
Beyond simple replacement, this board adds protective features that help prevent the next failure. A resettable circuit breaker guards the 12V DC side, a heavy-duty diode trips that breaker instantly if 12V is connected backward, and dedicated fuses cover the 120V AC heater circuit. A short-circuit indicator LED also flags wiring faults at the main switch or interior light before they can do further damage.
Onboard resettable breaker protects 12V DC circuits from short-circuit damage -- no inline fuse to hunt down and replace.
Heavy-duty diode trips the circuit breaker immediately if 12V DC leads are connected backward, protecting the board and downstream components.
Dedicated fuses on the 120V AC circuits guard against shorts in heater wires and the heating element.
Onboard indicator alerts you to shorts in the wiring to the main switch or interior light, making diagnostics faster and straightforward.
The P-246PLUS supports full 3-way refrigerator operation -- 120V AC shore power, 12V DC battery, and LP gas. This makes it suitable for RVers who switch between campground hookups and boondocking without wanting to think twice about which mode their fridge is running. All three operating modes are managed through a single board replacement.
This board is confirmed compatible with the following Dometic RM-series models:
Covers both old-style and new-style Dometic gas valves. Always verify your model number on the fridge data plate before ordering.
Dinosaur Electronics has built its reputation on boards that install without drama. The P-246PLUS uses the same connector positions and mounting footprint as the original Dometic board, so replacement is a straightforward swap in most cases. No custom wiring harnesses, no adapter kits needed for the compatible models listed.
Before installing, photograph the existing wiring connections. Label each connector with tape if needed. Confirm 12V polarity at the board connector with a multimeter before powering up -- the reverse-polarity diode is a last-resort safeguard, not a substitute for correct wiring.
The P-246PLUS carries a limited 3-year manufacturer warranty from Dinosaur Electronics -- one of the longest in the RV control board segment. Dinosaur boards are a go-to choice for RV service centers and experienced full-timers alike.
