First disconnect any appliances that pulls a lot of amps off that same circuit and test your grill. If this does not resolve your problem, then try another appliance such as a hair dryer to see if this also trips the GFCI. If the GFCI trips with another appliance, then it is time for the GFCI to be replaced. You can also try your grill on another GFCI outlet if it continues to trip the outlet it is more than likely caused by the hot rod as it is drawing nearly 200 Watts for the first eight minutes. In order to test if it is the hot rod, we recommend unplugging the hot rood connectors (purple and white wires with purple connector). Once you have disconnected the hot rod plug in your grill and turn it to 200 degrees. If the unit turns on and does trip the GFCI then this signals that the hot rod needs to be replaced. If the GFCI still continues to trip, then the next step is to disconnect the auger motor (red and white wires with red connector). Once you have disconnected the auger motor plug in your grill and turn it to 200 degrees. If the grill turns on, then we know that the auger motor needs to be replaced. If the GFCI still continues to trip, then the next step is to disconnect the blower fan (orange and white wires with orange connector). Once you have disconnected the blower fan plug in your grill and turn it to 200 degrees. If the grill turns on, then we know that the blower fan needs to be replaced. Note that these are three quick tests to check the GFCI and the status of the components in your grill. We only recommend running the smoker for a couple of minutes to perform the test. We also recommend that you place a bucket underneath the firepot to help catch any unburnt pellets during these tests.
