Hello
We use A PRO-Charge Freon Refrigerant Scale when charging to dial in the exact amount of refrigerant recommended by the factory nameplate. We also make sure we bleed the refrigerant of air before charging and and evacuate the system. We have charged and replaced over 1000 compressors and evaporators. We were trained by Whirlpool factory trainers to charge liquid on the low / suction side. We have NEVER had any issues charging this way . I believe your issues or secondary problem are a plugged braze on refrigerant line or filter dryer . You need to go back and evaluate the unit by putting g the gauges on to check your pressures.

If you replaced the defrost heater, thermostat, and main control board. I suggest you replace the two temperature sensors part numbers below. If a sensor is defective it will cause Ice/ Frost build up on the coil. If you replaced the sensors and still have an issue replace the main control board. We have had a few new bad control boards out of the box. Matt Ace technician

Here are the technical information sheets we have available. I also included a video on a PFS22 series refrigerator. Hope all is well on your end .Matt

This is the closest manual I have to your product sorry. There should be a diagnostic manual with your product. Did you check in the unit ?

Hello
If you ran it through diagnostics and it is not cooling you should have error codes. These error codes will give you the specific direction to go it for the repair. Without error codes we are just guessing.

E01 RC sensor value is outside the defined range
E02 FC sensor value is outside the defined range
E03 TCD senor value is outside the defined range
E15 Ambient sensor value is outside the defined range
E10 CM Eeprom
E11 DOM Eeprom
E20 Communication error between CM and DOM
E21 Communication error between DOM and IWD

Hello
Is it not cooling in the refrigerator and freezer ? Is it partially cooling at all in either section ? Is the compressor running? Have you looked at the evaporator frost pattern ? Is the evaporator fan motor running ? When you say not cooling there are too many variables. You need to give us specifics otherwise we are just guessing . You have two boards in the unit 1) Power Supply Board ) Main control board. If you have lights on in the unit that is a good indication your power supply board is functioning properly. You will need to run the unit through diagnostics to verify the proper diagnoses.

See technician diagnostics below in the links. Look at the service bulletin on this unit link below. This sounds like a possible sealed system issue. Matt Ace technician

Hello
Is your compressor running ? If not you need to look at the evaporator for an even frost pattern. That will tell you if you have a sealed system problem or a possible defrost issue. Matt Ace technician

Hello
See manual link below there is a troubleshooting guide starting on page #33 . If the inverter board is blinking its detecting a motor current voltage error. The cause cold be : 1) A bad condenser fan motor . 2) Locked up compressor . 3) Defective inverter board. You can purchase the inverter board and condenser motor at Repairclinic.com and buy it to try it for up to 1-year return policy. If you can OHM out the condenser motor you can eliminate that , if not get both parts and if they do not fix the issue you have a defective compressor. Matt Ace technician
