No power to Norcold refrigerator

Plugged into shore power you should have 120V AC power to trailer....

With 120V AC power you should have 12V DC power via the 'converter'

No 120V AC power than battery should supply 12V DC power

You need 12V DC power for fridge controls


As suggested check on trailer tongue for a small box that has battery positive cable going to it and cable from it going inside trailer.
That is a DC Circuit breaker. Some are auto reset and many are manually reset.
Look for small button on side to reset

Also need to check that you installed battery cables corrctly and not reversed.
Reversed polarity happens a lot when batteries are replaced. Battery cables are not standard colors.......can be black & white, can be red & green can combination----so trace battery cable to frame--that is n=ground/negative on battery.

If connected backwards then 'reverse polarity' fuse(s) on converter are probably blown (30A or 40A fuses---can be on back or front of converter)

With the shore power plugged in........
Check main AC power panel
Main circuit breaker closed...all individual circuit breakers closed and see if converter is in a circuit breaker OR if it has a cord that needs plugged into an outlet.


Then check ALL DC fuses in DC dist panel.......usually with main ac panel

You may have a tripped breaker in the battery's positive (+) lead. It is located close to the tongue. I would think that if the converter is supplying 12V power, though, it should supply enough current to operate the fridge.

If you had a momentary flash of lights from the fridge, you may have a short somewhere and the fuses may have blown again. Your new meter will verify that the fuses are good or bad.

The meter, commonly referred to as a multi-meter can be obtained at Home Depot, Lowes or Harbor Freight.

OK. Brand new marine battery. Fluid levels were checked and hooked-up to battery charger and charged the other day. Rig has been hooked up to 120V for past 24 hours. As I am new to all this diagnostic stuff - what kind of meter do I purchase and can I get it at Home Depot?

lets start at the source, even plugged into 120v you need a good charged 12v battery. so start at your battery. check water level and clean the post and connectors . . after that checks out. find the fuse that handles the frig, check.with meter.
