The dc plug on our primus 40l fridge/freezer isn't working. Does anybody know if they have a fuse? The power is right up to the lead end but when we put it into the fridge plug it won't work.

I assume you mean the 12v socket on the fridge?
The end of the lead has the plug.
Looking at a manual for a primus fridge, it is recommended that a fuse be included in the circuit to the fridge. This may indicate there is no internal fuse on the fridge itself.
Take a look at the area adjacent to the 12v socket. Can you see a bladed fuse of some kind?
Does it run OK on 240v?
What voltage measurement are you getting at the end of the 12v lead plug?
The fridge appears to have 3 different settings for low voltage cutout.
The voltage you are getting should be 12.8 volts or above, which indicates a full battery capacity. Any voltage drop in the circuit may reduce the voltage below the minimum necessary to overcome the low voltage cutout device.
The low voltage cutout device itself may also be faulty.
The chances are you need an expert to look at and
test the fridge operation both on 240vac and 12vdc and diagnose the problem.

Hi Sandman,
It works ok on 240v. Can't see a fuse. Over 12.8v at end of the plug. Can't see the dropout settings must only work when the plugged in but I'm sure it was 10.7 or thereabouts.
I think we need the expert. Thanks for your reply, if I find out what's wrong I'll post it.
Thanks again
Bob
