Your model number can usually be found on a data plate on the back, side or underneath of the appliance.
Your model number will be a combination of letters and numbers, sometimes separated by a dash (-) or a slash (/).
If the freezer or fridge door is not shutting securely anymore or you notice the appliance is not cold enough it could be due to a faulty door seal which results in air escaping from the inside of the appliance.
ForMySpares has the solution for you - this genuine magnetic freezer/fridge door seal will solve this issue.
