What the 00 error code actually means

Your Whirlpool freezer is displaying a diagnostic readout for the temperature sensor inside the freezer compartment. If the display shows 'OP' or 'SH' instead of a temperature number, it means the sensor or its wiring has a problem and the freezer cannot accurately read the internal temperature. This should be addressed promptly since a faulty temperature sensor can prevent the freezer from maintaining safe food storage temperatures.

Questions people ask about 00

What does 00 mean on a Whirlpool freezer?
Code 00 on a Whirlpool freezer activates a diagnostic mode for the FC (Freezer Compartment) thermistor, displaying the current temperature reading in Fahrenheit or Celsius. If the thermistor circuit is working normally, a numeric temperature will appear. If the display shows 'OP', the sensor or wiring has an open circuit with resistance above 88 kilohms. If it shows 'SH', a short circuit is present with resistance below 1,600 ohms.
Is it safe to keep using my Whirlpool freezer when code 00 is showing?
If code 00 is displaying a live temperature reading and the freezer appears to be cooling normally, the diagnostic mode itself is not dangerous. However, if the display shows 'OP' or 'SH', the freezer's control system cannot accurately monitor temperature, which means it may not maintain safe food storage conditions. In that situation, the freezer should not be relied upon until the thermistor circuit is repaired.
How much does it cost to repair a Whirlpool freezer thermistor?
A replacement FC thermistor for a Whirlpool freezer typically costs between $15 and $50 for the part alone, depending on the model. If professional labor is involved, total repair costs generally range from $75 to $200 including diagnosis and installation. In some cases, the fix is as simple as reseating a loose connector, which involves no parts cost at all.
How do I fix the 00 error code on my Whirlpool freezer?
Start by disconnecting power to the freezer and inspecting the thermistor wiring harness and connectors for visible damage, corrosion, or loose connections. With power disconnected, measure the resistance of the FC thermistor and compare it to the values in the wiring diagram. If resistance is above 88 kilohms or below 1,600 ohms, the thermistor or its wiring will need to be repaired or replaced.
Will resetting my Whirlpool freezer clear the 00 error code?
Code 00 is a diagnostic mode that is entered intentionally through a specific button sequence, so a power reset alone may clear the display. However, if the underlying cause is an open or shorted thermistor circuit, the fault condition will remain even after the display resets. The thermistor and its wiring must be tested and repaired to resolve the root problem.
