This error occurs when the grill fails to successfully initialize, or when the
controller is not working properly.
Unplug the power plug and wait 15 seconds. Plug power cord and follow
through instructions in Operating instructions section.
If problem persists, components will need to be replaced.
This error occurs when the controller fails to detect signal from the
solenoid due to poor wire connection, failure on the solenoid component
and/or failure on the controller.
Ensure the solenoid cable is properly plugged in to the controller.
If problem persists, components will need to be replaced.
This error occurs when the controller fails to properly identify the
positioning of the modulating valves due to poor wire connection, failure
on the ZONE A and ZONE B components and/or failure on the controller.
Ensure the modulating valve cables are properly plugged in to the
controller.
If problem persists, components will need to be replaced.
This error occurs when the
plugged in correctly, or when the controller or modulating valves are not
working properly.
Ensure the modulating valves cable is properly plugged in to the
controller.
If problem persists, components will need to be replaced.
This error occurs when the
plugged in correctly, or when the controller or modulating valves are not
working properly.
Ensure the modulating valves cable is properly plugged in to the
controller.
If problem persists, components will need to be replaced.
This error occurs when the RTD is not plugged in correctly, or when the
RTD or controller are not working properly.
Ensure the RTD is properly plugged in to the controller.
If problem persists, components will need to be replaced.
This error occurs when there is a clock error with the controller.
If problem persists, components will need to be replaced.
This error occurs when there is an overall system clock error.
Unplug the power plug and wait 15 seconds. Plug power cord and follow
through instructions in Operating instructions section.
If problem persists, components will need to be replaced.
This error occurs when ZONE A is off due to the propane tank being out
of gas, or when the controller is not working properly.
Replace gas tank and restart your grill.
If problem persists, components will need to be replaced.
This error occurs when ZONE B is off due to the propane tank being out
of gas, or when the controller is not working properly.
Replace gas tank and restart your grill.
If problem persists, components will need to be replaced.
This error occurs when the grill temperature is too high or if the RTD or
controller do not work properly.
Turn the dial to decrease the temperature.
If problem persists, components will need to be replaced.
This error occurs when the flame is not detected due to the RTD or
controller not working properly.
If problem persists, components will need to be replaced.
This error occurs when the ambient temperature around the controller is
exceeding 176 °F (80 °C).
Unplug the power plug and wait 15 minutes. Plug power cord and follow
through instructions in Operating instructions section.
