Good morning, the two lights at the top of the fridge will flash when the temp in the fridge and freezer is above the required temp normally, above 5 degrees for the fridge and -15 for the freezer.
So we need to understand why its stopped cooling, I would start by switching the unit off and let it fully defrost until its room temp in the freezer (this may take the remainder of the day). Then I would turn the fridge freezer back on and check its getting cold, after a few hours the ***** *****ghts should have stopped flashing, if they havent we need to look to get an engineer out, as it sounds like there is a coolant fault (most likely a faulty control panel).
Good evening, I havent heard from you, I just wanted to follow up to see if you require any further assistance?
Most likely some ice has got stock behind the rear compartment and causing fault reading to the temp sensors, if it reoccurs its worth doing a defrost, before calling someone out, as 80% of the time a defrost will fix this issue (so much for self defrosting appliances).
Please let me know if I can be of any further assistance.
