How Does a Gas Cooktop Work? — Appliance Repair & Tips



not all stovetops look the same but they operate on similar principles in this video we will address how a gas stove top operates as well as potential problems you may encounter each surface burner knob on the stovetop controls a burner valve when the knob is turned to the light position the valve opens allowing gas to flow from the manifold as the gas travels through the burner tube it is directed into the venturi where it combines with air to create the proper mixture necessary for combustion at the same time the spark switch closes allowing 120 volts of alternating current to travel to the spark module which produces high voltage pulses to all of the electrodes the pulses caused a spark to occur between the electrode and the grounded burner cap the gas and air mixture at the burner head is ignited by the spark and a blue flame with an occasional yellow tip is produced common problems that occur with this type of electronic ignition system are the electrodes sparking continuously sparking intermittently or not sparking at all if the electrode spark continuously one or more of the switches has probably shorted closed a short is usually caused by liquid getting into the switch if this happens you should unplug the appliance and give the switches time to dry out if the electrodes are still sparking continuously once the appliance is plugged back in one or more of the switches has probably failed and will need to be replaced if the electrode spark intermittently there is a high probability that the module is defective and will need to be replaced if one or more of the electrodes fails to spark at all the cause could be a defective switch that prevents the voltage from reaching the module the module could also be defective and failed to produce the high voltage pulses to one or more of the electrodes finally the electrodes themselves could be damaged to help determine this you can inspect the electrodes for cracks repair clinic has a solution for many of the problems you may be experiencing with your stovetop enter the appliances full model number in our website search engine for a complete list of compatible parts our site also has an extensive selection of instructional videos to assist you covering topics like part testing disassembly and part replacement at repair clinic we make fixing things easy you

    Unfortunately your site doesn't have a video showing how to open one of these things up.

    My GE cooktop has uneven flames and sometimes ends up burning pan bottoms. I see some rust on burner bottoms if that's related. What should I do?

    Do gas top burners need adjustment to create optimal heat output? I have a Maytag MGR5775QDS and it seems to take forever for the largest burner to bring  my large Wok skillet to temperature hot enough to sear meats and veggies.
