Digital Old Smokey electric smoker display shows E7 and the timer or temperature settings cannot be adjusted correctly.

Safety first: Unplug the smoker before performing any internal inspection. This error is usually electronic rather than mechanical.

Steps to attempt recovery from E7:

• 1. Perform a power reset: Unplug the smoker for at least 5 minutes to allow capacitors to discharge. Plug it back in and check if the E7 code clears.
• 2. Check power quality: Ensure the smoker is plugged directly into a properly grounded outlet, not a long extension cord or power strip. Voltage drops or surges can corrupt control memory.
• 3. Inspect the control board: Remove the control panel and visually inspect the board for burnt components or corrosion. If present, the board will likely need replacement.
• 4. Look for moisture or insect damage: Clean any debris carefully with a soft brush. Do not scrape or damage components.
• 5. Attempt factory reset (if supported): Some Old Smokey digital models may support a reset sequence (e.g., holding specific buttons while plugging in). Refer to the model-specific manual. If known, perform the reset and see if E7 clears.
• 6. Replace the control module: If E7 persists after power cycling and any available reset, the control board's memory or firmware is likely damaged. Replace the OEM digital control board.

Warning: Do not attempt to reprogram or modify the control firmware unless you are following official Old Smokey service procedures. Incorrect firmware can create unsafe operating conditions.
