Why is my KitchenAid Refrigerator compartment too cold?
- C
  Charlotte KirbyAug 21, 2025
  If your KitchenAid Refrigerator compartment is too cold, here are some possible causes: * The refrigerator control may be set too cold. Try setting it to a higher temperature. * The refrigerator thermistor could be malfunctioning. Check the wires and connectors. Run diagnostics, and if a defective thermistor is indicated, confirm with an ohms test. * The air door might be stuck open or inoperative. Look for ice or other blockages in the air door. Run a diagnostics test to operate the air door. Check for proper DC input voltage. If the voltage is normal and the door still won't operate, replace the air door. * The air door seal might be missing or damaged. Repair or replace the seal. * There could be an issue with the main PC board. Run a diagnostics test to operate the air door.

  Robert BaldwinAug 25, 2025
  If your KitchenAid Refrigerator's freezer compartment is too cold: * The freezer control may be set too cold. Set it to a higher temperature. * The refrigerator may be operating in Max Cool or Automatic Max Ice Mode. This is normal operation. * The freezer thermistor might be faulty. Check the wires and connectors. Run diagnostics, and if a defective thermistor is indicated, confirm with an ohms test. * There might be no evaporator fan motor feedback. The fan motor will run at 3000 rpm.

What to do if the 'Call Service' icon lights up on my KitchenAid KSSC48QKS00?
- R
  Ruben MartinezAug 28, 2025
  If the "Call Service" icon lights up and/or the alarm is activated on your KitchenAid Refrigerator, it could be due to several reasons: * The main control board may be overheating, possibly due to blocked condenser airflow or a malfunctioning condenser fan motor. Check these components. * The refrigerator temperature might be above 48°F or the freezer above 15°F for more than 3 hours. In this case, run diagnostics to test all components. * Both thermistors might have failed. Run diagnostics and test the thermistors and their leads. * There might be no feedback from the evaporator fan motor. Run diagnostics and test the fan motor and its wiring.

What to do if the condenser fan runs but the compressor won't start on my KitchenAid KSSC48QKS00 Refrigerator?
- D
  Diane BakerSep 1, 2025
  If the condenser fan runs but the compressor won't start on your KitchenAid Refrigerator, the following could be the issue: * There may be no DC control voltage from the main PCB to the inverter board. * The control voltage wires may be loose or reversed. Check the connections and repair as needed. * There may be an issue with the compressor. * There may be an issue with the inverter board.

Why does my KitchenAid KSSC48QKS00 Refrigerator run too long?
- G
  Gina AllenSep 5, 2025
  It is normal for your KitchenAid Refrigerator to run for extended periods. It is designed to run almost constantly at the lowest possible compressor speed because starting and stopping the compressor uses more power than continuous low rpm operation.

  Dustin WarrenNov 13, 2025
  If your KitchenAid Refrigerator compartment is too warm, there are several potential causes: * The refrigerator control might be set too warm. Try setting it to a lower temperature. * There might be an issue with the refrigerator thermistor. Check the wires and connectors. Run diagnostics, and if the thermistor is indicated as defective, confirm with an ohms test. * The air door could be stuck closed or inoperative. Look for ice or other blockages. Run a diagnostics test to operate the air door. * The evaporator fan motor may not be running. Run a diagnostics test to operate the evaporator fan motor. Check for a blocked fan blade and repair if necessary. Check for 5-17vdc from pin P7-9 to P7-10; if the voltage is correct, replace the motor. * There could be blocked airflow. Chec...
