indesit DLAA50 fridge Thermostat not working

I will try and help with this problem Indesit DLAA50

If your fridge is getting very cold in other words you are getting negative degrees in the compartment and freezing any liquid like beer or milk then ​your thermostat​ has gone and will need replacing​, but yet if the fridge is still only at +1 or +2 degrees then there's a possibility that you may be low on gas and this is a much more serious fault and will need an engineer to rectify it. I have added the part you need and a video to help you fit it below.
