If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Depleted RTC backup battery on main board, Faulty non‑volatile memory, Main board defect

Safety first: Turn OFF main power and disconnect the battery before accessing the main board.

Re‑enter settings: Confirm that settings can be saved during a single power cycle. If they reset only after long periods, the backup system is suspect.
Inspect RTC battery: Some boards have a small coin‑cell battery. If user‑replaceable, install a new battery of the same type and polarity.
Board replacement: If there is no replaceable battery or the problem persists, the Main Control Board likely needs replacement.
