The thermocouple (flame sensor) above the burner is not telling the control board that the flame is lit. Clicking should stop as soon as the burner lights. If it does not sense a flame after 30 seconds it will stop trying to ignite the gas and release the gas solenoid (turn off the gas).
Make sure the thermocouple is securely mounted above the igniter and the wire is connected to the control board.
The RM2454 Thermocouple part number is 293 20 52-01/8
