PURPOSE: A circuit for controlling a burner of a gas oven range is provided to simplify composition of the circuit controlling a solenoid valve and constant voltage. CONSTITUTION: A circuit includes a microcomputer(20) outputting control signal through output terminals 01, 02, 03 depending on selection of a user or preset algorithm to turn on/off a burner; a first transistor(Q11) receiving control signal of the microcomputer through a base thereof to be turned on/off; a second transistor(Q12) receiving control signal of the microcomputer through a base thereof to be turned on/off, and connected with a collector of the first transistor; a first solenoid valve(SV1) working depending on on/off of the first transistor and the second transistor; a third transistor(Q13) receiving control signal of the microcomputer through a base thereof to be turned on/off; a second solenoid valve(SV2) working depending on on/off of the third transistor; and a power source part(10) supplying constant voltage to allow the first solenoid valve and the second solenoid valve to work.
