The compressor will appear to freeze up if the evaporator fan stops running while the compressor is running. I would look for a defective evaporator fan if I understand you correctly. Fans will sometimes stop when they should be running. Defective fan does not always stop running when they go bad
Appliance 911 Sea Breeze

No the evaporator fan not running has nothing to do with the compressor. I would suspect that you are freezing up over the evaporator because the fan is not running and when it ices up the air can not flow through properly therefore causing the refrigerator side to get warmer. Replace the fan and you should be fine. Take the back panel inside the freezer off and see if you are all iced up. If you bare then I would replace the fan . You also said the defrost heater did not come on. That will also cause a freeze up. Possible replacement of the defrost heater may be needed. Good Luck!

This elaborates more on the code.
P0456 - Evaporative Emission System Leak Detected (Very Small Leak)
Description:
The powertrain control module (PCM) monitors the complete evaporative emission (EVAP) control system for the presence of a very small fuel vapor leak. The system failure occurs when a fuel vapor leak from an opening as small as 0.508 mm (0.020 inch) is detected by the EVAP running loss monitor test.
Possible Causes:
• Very small holes or cuts in the fuel vapor hoses/tubes
• Loose fuel vapor hose/tube connections to the EVAP system components
• EVAP system component seals leaking. See the Possible Causes for DTC P0442
Diagnostic Aids:
Check for a missing fuel filler cap or the integrity of the cap.
Check for loose or damaged vapor hoses. Visually inspect the EVAP canister inlet port, CV solenoid filter, and canister vent hose assembly for contamination or debris.

The motor is bad and needs to be replaced. Here is the assembly to order.

Replace the motherboard (part # WR55X10942) but be careful to check that the evaporator fan (inside the freezer) turns on when you power up the refrig again. A bad evaporator fan motor can take out the motherboard. If compressor starts with new board but not evap fan, unplug immeadiatelly and replace the evap fan motor to save new board.

Great ! ! Usually the main control board is the problem , when the evap fan doesn't run .

I believe that because defrost is done by the mother control board this is why this is happening the part of the board that controls defrost is malfunctioning and the only way to resolve the problem is to replace the mother board part number WR55X10656 You can find the replacement board at these places below.

P0455 - EVAP Control System Leak Detected (No Purge Flow or Large Leak) The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).

• Check for missing fuel filler cap.
• Check for loose fuel filler cap.
• Check for possible cross-thread fuel filler cap condition.

Is a fault present concerning the proper installation of the fuel filler cap? Yes No REPLACE cross-threaded or damaged fuel filler cap. RECONNECT and TIGHTEN the fuel filler cap only one eighth turn so that the cap initially clicks by sound or touch. CLEAR Continuous Memory DTCs. COMPLETE an Evaporative Emission Running Loss Monitor Repair Verification Drive Cycle (refer to Section 2 , Drive Cycles). RERUN Quick Test . If DTC P0455 or P0457 is present, Go to HX44 . CLEAR Continuous Memory DTCs. COMPLETE an Evaporative Emission Running Loss Monitor Repair Verification Drive Cycle (refer to Section 2 , Drive Cycles). RERUN Quick Test .

For DTC P0455 still present: Go to HX44 .

Otherwise, INFORM the vehicle owner that it is important and necessary to immediately install the fuel filler cap after every refueling event. HX44 DTC P0455: VISUAL INSPECTION FOR SUBSTANTIAL EVAPORATIVE EMISSION SYSTEM LEAKS

• Check for missing fuel filler cap. If the cap is loose DO NOT DISTURB EVAP system.
• Verify that both the input port vacuum hose and EVAP return tube are attached to the EVAP canister purge valve. Note: If the EVAP canister-CV solenoid assembly is not accessible during this pinpoint test step, GO to Evaporative Emissions, Section 303-13 in the Workshop Manual for removal and installation instructions.
  
• Verify that the CV solenoid is properly seated on the EVAP canister (if possible).
• Visually inspect for disconnected or cracked fuel vapor hoses/tubes between the intake manifold, the EVAP canister purge valve, the EVAP canister, the fuel vapor vent valve assembly and if applicable the fuel vapor control valve tube assembly.
• Check for damage to the fuel filler pipe and the fuel tank.

Is a fault indicated? Yes No CONNECT or REPLACE fuel vapor hoses/tubes as required. REPLACE damaged EVAP system components (fuel filler pipe, fuel vapor vent valve assembly, fuel vapor control valve tube assembly, EVAP canister purge valve, FTP sensor and EVAP canister-CV solenoid assembly) as necessary. REFER to Evaporative Emissions, Section 303-13 in the Workshop Manual for removal and installation instructions. GO to HX45 . GO to HX45 . HX45 DTC P1443 and P0455: CHECK FOR EVAPORATIVE EMISSION SYSTEM LEAKS

Note: When checking for leaks or blockages in the EVAP system, energize (close) the canister vent (CV) solenoid through the scan tool for a maximum of nine minutes per pinpoint test step. Then de-energize the CV solenoid prior to performing the subsequent pinpoint test step. This is done to assure proper closing of the solenoid.

• Disconnect and plug the EVAP return tube (EVAP canister purge valve to intake manifold) at the intake manifold vacuum source.
• Connect scan tool.
• Key on, engine off.
• Access VPWR PID. If the voltage is not 12 volts or greater, GO to HX61 .
• Locate evaporative test port [marked EVAPORATIVE SERVICE PORT DO NOT USE UNREGULATED PRESSURE ABOVE 6.89 kPa (1 PSI)] near EVAP canister purge valve or EVAP canister.
• If vehicle is not equipped with the evaporative test port, GO to HX50 .
• Install the Rotunda Evaporative Emission System Leak Tester 310-F007 (134-00056) or equivalent at the evaporative test port.
• Close CV solenoid by accessing Output Test Mode on the scan tool.
• Select ALL OFF mode and push START button.
• Regulate the nitrogen or argon gas pressure on the tester to 3.48 kPa (14 in-H 2 O).
• Follow the instructions that come with the EVAP System Leak Tester and pressurize the EVAP system.
• Perform the EVAP system leak test.

Does the pressure on the EVAP system stay above 1.99 kPa (8 in-H 2 O) and pass the leak test? Yes No GO to HX46 . REMOVE the EVAP System Leak Tester from the evaporative test port and REINSTALL the test port cap. GO to HX50 .
