Thermomax Walk In Fridge

[eSelena]

Hey guys,
my fridge's alarm has beeng going off randomly for the past week, but more importantly it can not stop decreasing the temperature. We set the lowest at 0, it stops around minus 6 - killing half of the foods.
I'm trying to buy another control - the Thermomax Coltrec RCX100 - but I can find it neither online nor at shops. And the Thermomax website is no longer active.
Does anyone know where I can buy another control? How much it roughly cost? or where can I find the manufacturer?
Thank you

Selena

I think Climate Center still deal with these or there are some on Ebay.

What Brian said or just fit a different make one if you can't get a thermomax one.
