HI

I have an hotpoint fridge freezer FFA70 the fridge is working fine but the freezer has a light on it that says high freezer temp. this happend 2 days ago. I turned the freezer down and it went off. Today it has come on again. I have turned it down to number 2 but it is still on.

I can't find the manual sadly, so was hoping someone on here may know what I can do?

The bottom drawer has a small build up of ice. I wondered if the freezer sensor maybe blocked or something?
