Possible Causes

How to Fix / Troubleshooting
Safety first: Disconnect power before opening the control box. Avoid static discharge to the electronics.
Steps to troubleshoot E9:
- Dry and clean control box: If the smoker has been exposed to rain or heavy condensation, remove the control box and allow it to dry in a warm, dry area for 24 hours. Do not use direct high heat.
- Inspect for corrosion: Open the control box and look for green or white corrosion on the circuit board. Light surface corrosion can sometimes be cleaned with contact cleaner and a soft brush.
- Power cycle: After reassembly, unplug the smoker for 10 minutes, then reconnect to perform a full reset.
- Surge protection: Use a quality surge protector to prevent future firmware corruption from power spikes.
- Replace control box: If E9 continues, the control board firmware or memory is likely damaged beyond field repair. Replace the complete digital control box.
