Timer counts down but the cooker does not heat; food remains cold.

Safety: Unplug and cool the unit before accessing internal components.

• Listen for relay click: When starting a program, you should normally hear a faint click from the relay. Absence of this sound may indicate a relay or control issue.
• Test heating element: Measure resistance across the heating element terminals. Infinite resistance indicates an open element that must be replaced.
• Check wiring and cutoff: Inspect the wiring from the board to the element and any inline thermal cutoffs. Replace any open or burned components.
• Replace main board: If the element and wiring are good but the relay does not energize, replace the main control board.
