Norcold 1200 LRIM model. Beeping low dc but stops when i open either fridge door. House battery shows 13.6 with rv running and it is beeping with rv running. It starts beeping again a minute or so after door is opened and closed. Any ideas?

If you leave the doors open for more than a minute, what beeping or indicator do you get? 1200 models have a beeping that will indicate if the door light switch is NOT closed. You have to adjust the door up to stop that indicator. The 12 volt power MUST be read at the input to the refer, not just what the house battery shows. The refer is sensing lo DC voltage, so check the voltage at the refer 12 volt input with a digital voltmeter. When you open the refer door, the rear fans also stop and that may mean the voltage is just at the minimum. When you close the door those 2 fans start up again. Doug
