US units are equipped with two BRAHMA TGRD81 flame control boards installed for each oven. The two
flame control boards work synchronized and both must give the power input to the gas valve to make it open.
There can be a maximum of 3 ignition attempts in total, after that the oven will give an AF23 alarm.
