GE chest freezer, 6 years old, something like 19 cubic feet,
model FCM7DRBWH.

The temperature runs to -15 to -10 degrees F when I have it on the
warmest setting, which is to say it is colder than what I want, namely 0
degrees.

I am afraid it may be wearing out its compressor.

What is probably wrong?

Thanks.
