when it is turned on, it doesnt make the clicking ignite sounds. None of the four burners work
It sounds like you have an auto-ignite system with no pilot lights. Since you do not hear a click I would say that the safety device is most likely functioning properly. Your ignition switch has gone out. You can contact the manufacturer and get a replacement switch or you can buy a replacement BBQ ignition switch and rewire it yourself. Replacing an auto-ignite with a push button ignite is really not that difficult and might save you a few bucks.
Mine has to be plugged in for the igniters to work, if yours is, check for a tripped breaker or maybe a blown fuse in the stove I can light the burners on mine with a match if there's no power.
