Domestic freezer advice

[Paul Drawmer]

Our upright freezer in the garage is struggling with the heat. It is 25 years old.
It is not frosted up, it does not have dirty heat exchanger coils etc.

The ambient temp in the garage is going up to 35C and it can't cope. It used to do fine, but now I'm having to help it with a big fan blowing over the back.

It hasn't 'failed' it's like me, and struggling with old age. What's likely to be the problem, my suspicion is that the compressor may be wearing out. Is that likely?

If it is the compressor, I guess that's not a £50 repair?
