Timer or delayed start function does not work; cooker starts immediately or not at all.

Safety first: No internal high-voltage work is needed for basic checks; unplug only if opening the unit.

Steps to check:

• Confirm procedure: Recheck the user manual for the correct sequence to set delay and program. Many issues are due to incorrect button order.
• Test buttons: Ensure the +/- and Timer buttons respond reliably. If not, see keypad repair steps.
• Reset unit: Unplug for 10 minutes to reset the control. Try setting the timer again.
• PCB replacement: If the timer consistently misbehaves despite correct use and good buttons, the control PCB may need replacement.
