Whirlpool Oven Error Code F03

F03 indicates an EEPROM failure on the Antares or Capricorn control module. The EEPROM is a memory chip that stores the oven's operational settings and calibration data. When the control system cannot read or write to this chip correctly, it triggers F03 and prevents normal oven operation. Resolving it requires either reprogramming the Antares EEPROM with a SAM tool or replacing one of the control modules.

It is not recommended to continue using the oven while F03 is displayed. The error indicates the control module's memory is not functioning reliably, which means the oven may not regulate temperature, timing, or safety functions correctly. The oven should remain off until the fault is diagnosed and repaired.

Repair costs for F03 vary depending on which component needs to be replaced. Control board parts typically range from $100 to $300 or more depending on the specific module, and professional labor adds additional cost that commonly ranges from $75 to $200 depending on your area. If the fault is resolved by reprogramming the Antares EEPROM rather than replacing a board, the cost may be limited to the service call fee.

DIY repair of F03 is limited without professional tools. The recommended first step is replacing the Capricorn module, which is a part swap a skilled DIYer can perform. Reprogramming the Antares EEPROM requires a SAM (Service Assistance Module) tool that is typically only available to trained technicians. If you are comfortable replacing control boards and can source the correct part, that portion of the repair is manageable at home.

A power reset, such as unplugging the oven or tripping the circuit breaker for a few minutes, may temporarily clear the F03 code if the fault was caused by a one-time data corruption event from a power surge. However, if the Capricorn or Antares module has an underlying hardware failure, the code will return. A reset should be treated as a diagnostic step, not a permanent fix.
