How Does a Gas Range & Oven Work? — Appliance Repair Tips



not all ranges look the same but all of them feature a stovetop and oven which operate on similar principles in this video we will address how a gas range 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 assured 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 a gas of an ignition system consists of three basic components the oven control the igniter and the oven safety valve the oven control may be switch based with a thermostat and sensing bulb assembly or an electronic control board that works with an oven sensor when you select the bake or broil the control sends 120 volts of alternating current to the appropriate igniter the igniter is wired to the safety valve and as the igniter starts to get hot it draws an increased current or amps through the valve inside the valve is a bi-metal arm that reacts to the heat generated by the amps once sufficient amps pass through the valve the arm flexes and opens releasing gas into the oven burner tube the gas travels through the burner tube until it reaches the bake or broil igniter by this time the igniter temperature is over 2,000 degrees Fahrenheit so the gas is easily ignited and the appropriate burner will begin to heat the igniter remains on to keep the safety valve open until the oven reaches the designated cooking temperature the temperature is monitored by the sensing bulb on the thermostat or by the oven sensor when the selected temperature is reached the oven control shuts off the voltage to the igniter the arm inside the safety valve closes shutting off the gas supply to the burner this cycle repeats throughout the cooking process to maintain the proper temperature keep in mind the cooking temperature designated by the control is only an average the actual temperature will fluctuate throughout the cycle convection ovens will reduce this fluctuation by using a motorized fan with or without its own heating element to circulate the heated air evenly throughout the oven cavity if any of the ignition system components fail the oven will either not heat at all or heat improperly the component that most commonly fails is the igniter if your ovens bake or broil burner is not working remove any covers or shields and observe whether or not the burners igniter is glowing if the igniter is glowing but the burner has not been lit after 90 seconds there is a high probability that the igniter has weakened and is unable to draw the proper amps to open the safety valve and light the burner in this case the igniter should be replaced if the igniter is not glowing you should test both the igniter and the safety valve to determine if one of them has stopped functioning if one or both of the burners are still not working the oven is overheating or the temperature is off by more than 40 degrees Fahrenheit once preheated the oven control is probably defective if your oven has a switch based control with a thermostat and sensing bulb the entire assembly will need to be replaced if your oven has an electronic control the oven sensor can be tested to determine whether the sensor or the control board is the source of the problem repair clinic has a solution for many of the problems you may be experiencing with your range enter the appliances

    My oven heats up, but then the whole oven seems to electric short and cuts off. Clock goes out, makes a rejecting beep noise, and I have to pretty much beat it by closing the oven door for it to come back on.

    Also the gas stove top takes a while to ignite sometimes.

    I am thinking I will get a new oven soon haha

    Sadly, I have the same black stove and it didn't have clips. The top was held on by a bracket. Had to also remove the knobs and that panel to access 2 more screws to release the lid. All this after an hour of frustrating pulling, poking and screaming at it.

    My gas range works, but the oven doesn't work because there is no flame, so what can be the cause and what is the solution?

    Update: the faulty burner doesn't spark when I turn its knob. But the faulty burner does spark when I turn the other knobs. Please advise.

    Hi, I have a GE XL44. 2 burners on the left side light fine, but the ones on the right can only be lit after I light the left side one first. The ones on the right click ok, but don't light without lighting the left side first. Please advise as to switch, igniter, or other replacement part that i need. Thanks.

    I was all set to watch this out of curiosity and luckily you used my exact Frigidaire oven as your example. Thank you I'm also using your other bake burner ignitor video to replace mine.

    why the hell would anyone want to mess with this dangerous crap, get an electric oven.  I've used both gas & electric & I never went broke on my electric bill with my electric stove, used the same amount of money per month & I had no danger of blowing up or carbon monoxide.
