gbendaly, If you have a WAECO cabinet refrigerator it could be powered by a separate small AC/DC voltage converter. These units have caused voltage drop during battery power compressor starts.

If your unit is powered only from DC power there is a problem with the boat’s wiring. A normal voltmeter will not detect the degree of low voltage spike that will trip the low voltage safety circuit in a Danfoss module. A power wiring loop of 5 meters of small diameter wire or any resistance detected through wiring will cause a no start compressor problem. To correct this problem you should use 6 mm or 10 mm fused wire direct from positive and negative battery busses. Do not pick up power or ground from a branch circuit like a breaker panel. If there is more than one battery bank connect fused power wire to common terminal on battery selector switch.

That happened to me Freshspearit, and I solved the problem with a new module.

I was just going to refer gbendaly to kollmann-marine.com :: View Forum - Refrigeration for Boats before I saw Richard Kollmann's name...lol
