  • Patent number: 11619386
    Abstract: A digital gas cooking appliance is disclosed. The digital gas cooking appliance has the ability of self-initiating an automatic calibration process to determine an optimum valve position to be used for an electromechanical valve when igniting a gas cooking element by performing a plurality of ignition sequences for the gas cooking element at a plurality of respective valve positions of the electromechanical valve. During each of the plurality of ignition sequences, a respective ignition duration between a start of the respective ignition sequence when an igniter is active and the electromechanical valve is open, and a flame is detected by a flame detector, may be determined.
