Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
If you can look in the fridge or freezer compartment there is a label stuck to the left hand side model number usually starts with an R or and S such as RS21***********/**** once you have it come back to me ~ Ian
OK excellent, with the power on press quick freeze and fridge temperature together and hold in for up to ten seconds, let me know what you get?
OK try this ~ it causes a factory reset ~ press quick freeze and vacation button together and tell me what you have got?
OK you have two pcbs with this appliance, one is the display board the other the power control board at the back You have likely got a problem with either the control board or the display board, both are fairly expensive as you have no motor action and or display just finally do this for me ~ switch off the appliance for a couple of minutes and switch it back on listed for a loud clunk and then report back
Printed circuit boards ~ OK from what you have told me it would seem that the main power printed circuit board which can be found in the motor area at the back has failed and will need replacing ~ Ian
