I'd say your thermostat has failed. They do sometimes fail in a
gradual manner. Try bypassing the thermostat for a while to see if the
mechanicals work.
Right. Well, just check the temperature where the thermostat turns on and
off. Since you say the thermostat IS cycling it on and off, it really does
sound like the thermostat has failed. You could bypass the thermostat and
see how cold it gets when running full on for a couple hours.
