Smoker will not start a cook cycle; pressing Start does nothing though display is on.

Safety first: Ensure the smoker is on a stable surface and unplug before testing switches.

• Confirm door closure: Close the door firmly until the latch engages. Some models require a solid closure to activate the door switch.
• Test door switch: As described in the E10 procedure, verify the door switch operates correctly and replace if needed.
• Reset control: Unplug the smoker for 5 minutes to reset the control board, then plug back in and attempt to start a cycle.
• Check keypad: If other buttons work but Start does not, the keypad may be failing and require replacement.
