foster fridge

[ragworm1511]

Hi people,
i know it's a bit vague but i've just had a glance at a 3 door Foster fridge which was displaying a temp of 25c with all 3 symbols illuminated(alarm,fan and compressor).
This was in my local kebab shop and i had had a pint so will be going back tomorrow to investigate.
Any suggetions would be gratefully received,

Ta!

Could be anything, can you describe the controller to start with so we know age. LAE,Eliwell, Foster FSC ect

Can you describe it, Oval, rectangle, size ?

Could be anything, but if its in a kebab shop the condenser is probably full of ####.
The controllers on the older ones are nothing special so its probably just an over temp alarm. Just start with the basics, clean coil, check fans, check gas level and pot is pumping and im sure the fault will be obvious
