Hi, welcome to Just answer
Please tell me its complete model number and how old is it ?
OK and both burners are right side or left side burners ?
do you also hear a click sound ?
As the right side works fine so it seems the ignition unit and spark generator are fine
a moment please
just checking its parts
I believe the wiring to and from the control has to be checked ... the cost of repair should be around £110 including parts
also the electrics to the igniter should be checked
if they are fine then the left side control has to be replaced
