• Reset your controller:
• STEP 1: Power OFF your cooking device.
• STEP 2: Unplug your cooking device from the wall.
• STEP 3: Wait 5 minutes, plug it back in.
• STEP 4: Your controller is reset - check to see if the problem persists.

• Check your temperature sensor:
• Power OFF your cooking device.
• Your temperature sensor may not be plugged in correctly, or it is dirty.
• Remove the temperature sensor, clean the plug with a cloth, reconnect.

• Confirm the wires are connected properly and correctly. Refer to your instruction manual for more details.
• Check the controller for visual damage or water penetration. Water can damage your controller.
• Check the fan for visual damage. Are there any cracks or damages in the fan or fan housing?

• Check the wall plug:
• Make sure the breaker or GFCI is not tripped. Make sure the unit is plugged into the wall.
• If you are using an extension cord, make sure it is an outdoor grounding -type 3- wire cord, marked with the suffix “W” and with the statement, “Suitable for Use with Outdoor Appliances”.
   
• Check the doors / lids:
• Close all the doors and lids.
• The fan will not run if the hopper lid door is open, the ash door is open, or the lower door on the Digital Charcoal Smoker is open.
