Warranty Information
Features a one-year full warranty on the refrigerator, with additional limited warranties for specific components.
The KitchenAid Counter Depth Refrigerator Constant Flow Temperature Management System uses two thermistors to monitor temperature changes. The electronic control manages the variable capacity compressor, variable speed evaporator fan motor, and a variable position air door for independent temperature control of refrigerator and freezer compartments. It prioritizes fan speed before increasing compressor speed for efficiency, aiming for a constant run time at the lowest possible speeds. The Adaptive Defrost Control uses pulsed defrost technology. The control also monitors water usage and alerts when the filter needs replacement. Temperature settings are adjusted via up/down keys, with LEDs indicating the selected temperature.
Troubleshooting and error codes
| PROBLEM | POSSIBLE CAUSE | TEST PROCEDURE-ACTION |
|---|---|---|
| Condenser fan runs but the compressor will not start. | No DC control voltage from main PCB to the inverter board. Control voltage wires loose or reversed. Compressor. Inverter board. | See "Component Testing" section for main PCB test procedure. Check connections and repair as needed. See "Component Testing" section for compressor/inverter test procedure. See "Component Testing" section for compressor/inverter test procedure. |
| Refrigerator compartment too warm. | Refrigerator control set too warm. Refrigerator thermistor. Air door stuck closed or inoperative. Evaporator fan motor not running. Blocked air flow. Warm freezer compartment. | Set to a lower temperature. Check wires and connectors. Run diagnostics and if a defective thermistor is indicated, confirm with ohms test. See "Component Testing". Look for ice or other blockage in air door. Run diagnostics test to operate air door. Run diagnostics test to operate the evaporator fan motor. Check for a blocked fan blade and repair as necessary. Check for 5-17vdc from pin P7-9 to P7-10. If voltage is correct, replace the motor. Check air door outlet and air returns for blockage. See "Freezer compartment too warm." |
| Refrigerator compartment too cold. | Refrigerator control set too cold. Refrigerator thermistor. Air door stuck open or inoperative. Air door seal missing or damaged. Main PC board. | Set to a higher temperature. Check wires and connectors. Run diagnostics and if a defective thermistor is indicated, confirm with ohms test. See "Component Testing". Look for ice or other blockage in air door. Run diagnostics test to operate air door. Check for proper DC input voltage. If voltage is normal and door will still not operate, replace air door. Repair or replace seal. Run diagnostics test to operate air door. |
| Freezer compartment too warm. | Freezer control set too warm. Freezer thermistor. Evaporator fan motor not running. Condenser fan motor not running. Frost blocking evaporator. | Set to a lower temperature. Check wires and connectors. Run diagnostics and if a defective thermistor is indicated, confirm with ohms test. See "Component Testing". Run diagnostics test to operate the evaporator fan motor. Check for a blocked fan blade and repair as necessary. Check for 5-17vdc from pin P7-9 to P7-10. If voltage is correct, replace the motor. Check for a blocked fan blade and repair as necessary. See "Component Testing" section for condenser fan motor test procedure. Run diagnostics test to operate defrost system. Test defrost heater and bi-metal. |
| Freezer compartment too cold. | Freezer control set too cold. Freezer thermistor. | Set to a higher temperature. Check wires and connectors. Run diagnostics and if a defective thermistor is indicated, confirm with ohms test. See "Component Testing". |
| Refrigerator runs too long. | No evaporator fan motor feedback. Normal. | The fan motor will run at 3000 rpm. It is designed for this refrigerator to run almost constantly at the lowest possible compressor speed. Starting and stopping the compressor uses more power than continuous low rpm operation. Instruct customer. |
