GE Refrigerator Error Code 01

Code 01 on a GE refrigerator indicates that the unit is in Test Mode 1, a diagnostic mode activated by pressing the test button once on the main PCB. In this mode, the compressor runs continuously, both BLDC motors operate at defined speeds, the defrost heater is turned off, and the stepping motor damper is fully opened. This is not a fault code in the traditional sense; it is an intentional service mode used to evaluate refrigeration component performance.

Leaving the refrigerator in Test Mode 1 for an extended period is not recommended. In this mode, normal temperature regulation and defrost cycling are bypassed, which means food safety temperatures may not be maintained properly and frost buildup could occur. Exit the test mode as soon as diagnostic work is complete.

If code 01 was triggered accidentally or intentionally for testing, there is no repair cost since simply exiting the test mode restores normal operation. If the cause is a faulty main PCB, replacement board costs typically range from around $100 to $300 or more for parts, with additional labor charges if a technician is needed. Wiring harness repairs, if required, generally fall in the lower end of that range.

To exit Test Mode 1, locate the test button on the main PCB and follow the appropriate exit sequence for your model, which typically involves pressing the button again or waiting for the mode to time out. Once exited, the refrigerator should return to normal operation. If the code reappears without any button interaction, inspect the PCB and its wiring harness for faults.

A power reset, such as unplugging the unit for a few minutes, may clear Test Mode 1 and return the refrigerator to normal operation. However, if the mode was activated by a stuck button signal or a PCB fault, the code could return after the reset. Identifying and addressing the root cause is important if the code comes back without a deliberate button press.
