Jenn-Air Refrigerator Error Code PA

The PA code on a Jenn-Air refrigerator is a positive diagnostic indicator, not a fault or failure alert. It appears during the built-in service test mode and signals that a thermistor or fan component has completed its test cycle successfully. This code is part of the refrigerator's self-diagnostic system, which allows technicians to evaluate individual components in isolation without needing external test equipment for every check.

Thermistors are temperature-sensing resistors whose resistance values change predictably with temperature. During diagnostic mode, the control board sends a test signal to the thermistor circuit and evaluates the response. A PA result confirms the thermistor returned a resistance value within the expected range for its current ambient conditions. Similarly, for fan tests, PA indicates the fan motor received its test signal and responded correctly, confirming the motor windings and control circuit are functioning as intended.

Because PA is a pass result rather than an error, it requires no corrective action. Technicians typically encounter this code when walking through a structured diagnostic sequence to confirm component health after a repair or during a no-fault-found investigation. If PA appears during routine diagnostics on all tested components, the refrigerator's sensing and air circulation systems are operating within normal parameters.
