My Continental commercial freezer keeps tripping a 20 amp breaker every hour after reset. It is a commercial freezer that draws 9 amps. I had the 20 amp breaker replaced with a new one, also replaced the plug, and it still trips the breaker. It has a brand-new compressor and a brand new thermostat. What could the be the problem?

If you have a single pole breaker - 120 volts, not 240 volts...
Your freezer should have a serial data tag. Verify that the unit is labelled as 115, 117 or 120 for volts and 1 for phase. I am assuming this tag is where you obtained the info that it draws 9 amps.
Also verify that the replacement compressor was 120 volt.
A compressor will draw a fixed amount of power when running (after startup). If your freezer is 240 volt, 9 amp - that would mean it would draw 2160 watts of power (240 times 9). If that freezer were connected to 120 volt it would draw 18 amps (2160 divided by 120) and the inrush of the compressor starting would trip your breaker.
Another possibility is that your 120 volt power is dropping. If your power is dropping to half voltage - 60 volts, this would also result in an 18 amp draw to the load. You would see a voltage drop on your power source - any lighting would be very dim.
