How to Fix 42 Error

This is a system error on a Family Hub refrigerator, often indicated by flashing blue interior lights.
The primary fix is to perform a hard reset of the refrigerator.
Turn off the power to the refrigerator at your home’s circuit breaker.
Wait for at least 5 minutes before turning the power back on. This allows all the electronic components to fully reset. The error should clear upon startup.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
