Why is my Whirlpool GC5THGXKB00 Refrigerator compartment too warm?

  If the refrigerator compartment in your Whirlpool Refrigerator is too warm, first, make sure the refrigerator control isn't set too warm; try setting it to a lower temperature. Inspect the refrigerator thermistor's wires and connectors, and run diagnostics; confirm with an ohms test if a defective thermistor is indicated. Also, check the air door for ice or blockages and run a diagnostic test to operate the air door. Ensure the evaporator fan motor is running by running a diagnostic test, checking for blockages, and checking the voltage from pin P7-9 to P7-10 (it should be 5-17vdc); replace the motor if the voltage is correct. Finally, check for any blockages in the air door outlet and air returns. Note that a warm freezer compartment can also cause this issue.

  If the freezer compartment in your Whirlpool Refrigerator is too warm, ensure the freezer control isn't set too warm by setting it to a lower temperature. Check the freezer thermistor's wires and connectors, and run diagnostics; confirm with an ohms test if a defective thermistor is indicated. Run a diagnostic test to ensure the evaporator fan motor is running, check for any blockages, and verify 5-17vdc from pin P7-9 to P7-10; replace the motor if the voltage is correct. Check the condenser fan motor for blockages and test it. Finally, run a diagnostic test to operate the defrost system and test the defrost heater and bi-metal if frost is blocking the evaporator.

  If the refrigerator compartment in your Whirlpool Refrigerator is too cold, first, ensure the refrigerator control isn't set too cold; adjust it to a higher temperature. Check the wires and connectors of the refrigerator thermistor, run diagnostics, and confirm with an ohms test if a defective thermistor is indicated. Look for ice or blockages in the air door, run diagnostics to operate it, and check for proper DC input voltage; replace the air door if the voltage is normal but the door still doesn't operate. Finally, inspect the air door seal for damage and repair or replace it. The main PC board may also be a cause.

What to do if the condenser fan runs but the compressor won't start in my Whirlpool Refrigerator?
- C
  Christopher CharlesAug 27, 2025
  If the condenser fan is running but the compressor won't start in your Whirlpool Refrigerator, it could be due to several reasons. There might be no DC control voltage from the main PCB to the inverter board, requiring a test procedure in the "Component Testing" section. Check for loose or reversed control voltage wires and repair them if needed. The compressor or inverter board itself might be the issue, requiring testing as described in the "Component Testing" section.

Why does my Whirlpool Refrigerator run too long?

  Rebecca WilliamsSep 1, 2025
  It is normal for Whirlpool Refrigerators to run almost constantly at the lowest possible compressor speed. Starting and stopping the compressor uses more power than continuous low rpm operation.
