My Controller or Fan isn't Working Correctly
Do This First
Reset Your Controller
- Power OFF your cooking device.
- Unplug your cooking device from the wall.
- Wait 5 minutes, plug it back in.
- 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.
- Power OFF your cooking device. Make sure your device is not hot.
- Check all of the wire connections for visual damage. Check the fan, controller, doors, lids, and switch connections.
- 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 for debris in fan. You may need to remove the fan cover to remove any debris that has gotten into the fan. To remove the fan cover, remove the 4 screws in the corners of the fan shroud.
- Check the switches for visual damage.
- If any components have failed visual inspection, they should be replaced. Contact Masterbuilt Customer Service.
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.
—Your fan will turn off in the middle of a cook once your set temperature has been reached.
—The fan will turn back on once the temperature is below the set temperature.
—An error code will display on your cooking device control panel starting with "Err" followed by a number.
—It is normal to see the "V" and "R" code when you plug in your cooking device. This is not an error.
—An alarm will sound when your meat probe reaches the set temperature. This is not an error.
