12 Volt Frig Relay
Thinking of installing a 12v relay to isolate my Dometic cube frig from the Batt. when the engine is off. Reason: The frig LP flame goes out when traveling. This would be used sparingly for short run...

To answer a few questions. This is a small dometic fridge commonly called a cube fridge because the dimensions L-W-H are equal. These older friges do not have a circuit board. The LP flame is lit manually. The 12v heater has an on/off switch (fused) to turn 12v use off. To power the 12v heater I would have to connect into the 12 circuit or batt. preferably. On this 2000 Ford PU the OEM 12v relay kills the 12v circuit but the Frig is connected to the batt. and will draw power. Could flip the fused switch but if I forgot .....well you know. Soooo I would place this new relay between the frig and the RV batt. I would place the frig in the 12v position only when starting out if the frig was warm other wise the frig would stay cold enough until the next stop and LP operation resumed. When traveling the LP flame is not 100% reliable much like the driver.
