Do I need to replace the compressor and thermostat if we want to o use it as a refrigerator long term?
Nothing is (likely) wrong with your compressor.
The increase follows normal physics, as compressor capacity goes up when it has to handle a lower temperature difference.
Capacity has gone up, and so did efficiency while running time has dropped significantly.
Thus total energy consumption
has also gone down.
Check the spec sheet, and you can see for your self:
You may be able to reduce energy consumption
even further, depending on your installation
The aim is to reduce compressor speed and increase % running time.
A well designed appliance will do this by it self.
A simple installation
may have a resistor on the Electronic unit that sets the speed.
This is all described on the spec sheet.
Basically you can try detaching the resistor - that should drop the speed to 2000RPM - the lowest possible.
