stupid fridge compressor

[Richard Kollmann]

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.

thanks Gordmay for the detailed precise info

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
