ENGLES WON'T WORK

I had this same problem a few weeks ago... worked on 240 in-vehicle but not very well on 12V. 0-5C when 240 delivered (-)16!

I had 12V everywhere I needed 12V

check your earth!!

at the plug, between the plug and vehicle body

I cured a similar problem by very carefully bending the 3 prongs at the bottom where the 12v cord plugs in. This seemed to improve the quality of the contact, and all worked again. Cheers, Graham.

Thes edon't use much power but the connections have to be tight on the pins so I squeezed mine with pliers to clamp it up and is now very tight to push in and contacts reliably.
If you use a 50 watt down light globe and plug it into the fridge plug it will load test the plug for you. Not good light and good volts at pins means the cable or the cig socket is crook. Cig sockets get corroded too and won't pass current. Sort of electrical constipation.

The voltmeter/multimeter only reads a voltage level and not an amp flow so although an indicator, as mentioned it is only a sign there is voltage but maybe no flow.
Go with the flow.

Is it mounted in a vehicle? Is the socket original or one you have fiitted? Is it in a camper? Is teh camper earthed... etc
Can you try the fridge plugged into another car/12V?

Back probe each joint while the fridge is trying to start, that way you will find the problem.

As already mentioned it could be a loose earth or even a corroded fuse.
