Timer counts down too fast or too slow compared to real time.

Safety first: Unplug the unit before any internal inspection.

• Step 1 – Verify with a clock: Run a 10-minute cycle and compare to an accurate clock to confirm the timing error.
• Step 2 – Power reset: Unplug for 10 minutes and retest.
• Step 3 – Check power stability: Avoid using long extension cords or circuits shared with heavy appliances that may cause voltage dips.
• Step 4 – Replace control board: If timing remains inaccurate, replace the main control board, as timing is controlled by its internal oscillator and firmware.

Warning: Inaccurate timing can lead to undercooked or overcooked food; adjust manually until repaired.
