The Combustion Fan is Not Running / Operating CorrectlyUpdated a month ago
There is no need to worry if your fan does not operate at a constant speed. A variable speed fan will run at different RPMs and may pulsate to maintain a stable and precise temperature.
The fan should run continuously from cycle 2 during start-up until the grill completes the fan mode upon power down. If the fan is making noise or is not running at all, follow these steps to check its operation.
ALWAYS MAKE SURE YOU UNPLUG YOUR GRILL before you start looking over any parts.
- Turn off and unplug the grill. Once it has cooled down, remove the protective grate under the hopper box. Gently flick the fan blades with your finger to ensure they spin freely and show no visible damage. If the blades are damaged, you will need to replace the combustion fan, which is a straightforward process.
- Check the wiring: Examine the wires leading to the combustion fan to ensure the connections are secure and undamaged. Also, make sure the wires are not hitting the blades while they are spinning, as this could create noise and potentially damage the wires.
- Test the operation of the fan: When starting the grill, it will go through the initial start-up process. If the fan does not activate during step 2, it may be faulty and will need to be replaced. Combustion fans can be purchased through the Hark BBQ website or by sending an email to HARKBBQ.
