When the cleaning process is complete, the fine ash left in the oven can be wiped off the surface.Ĭatalytic self-cleaning ovens are coated with a special finish the allows most dirt to burn away at normal cooking temperatures. The smoke produced by the burning is vented from the oven. Pyrolytic ovens use very high heat - usually 1,000 degrees Farenheit - to incinerate food on the oven's surface, leaving only a fine ash. There are two types of self-cleaning ovens, pyrolytic and catalytic. Learn more about how to provide routine maintenance for an electric range in the next section. If you aren't able to relight this system, call a professional service person.Electric ovens and ranges are growing in popularity, probably because most repairs involve simply replacing a worn or faulty part. It should take about a minute to light this pilot. On this type of system, relight the pilot by depressing the reset button and holding a match to the pilot. If the pilot light goes out, no electricity is generated, and the valve closes to turn the gas off. A small amount of electricity holds the facing valves apart. The thermocouple fitting is next to the pilot valve, as in most burner systems. If this unit malfunctions, don't try to fix it yourself you should call a professional service person for repair or replacement.An electrically operated shutoff valve used on some gas ranges has two facing valves, an electromagnet, and a manually activated reset button. On some ranges, there is an automatic shutoff valve located in the pilot assembly that shuts off the gas to the burner any time the pilot and the burner are both off. The pilot will heat the controls to the ignition switch. On some oven pilots, turn the control to the OFF position and light the pilot then turn the oven dial to the BROIL position. It should not be as high as the top pilot flame leave it as low as possible. Experiment, turning the screws a little at a time, until the flame is adjusted properly. The ignition unit could also be located below the pilot follow the gas line down until you locate it. Next to the pilot, locate a small boxlike unit with a couple of screws in it. Call a professional service person for replacement. When an electric ignition device fails, don't try to fix it. As a rule, these ignition systems are sealed and cannot be repaired or adjusted. The heat from the filament lights the gas. In this type of system, an element becomes hot and glows like the filament in a lightbulb when an electric current passes through it. Instead, the gas is ignited by an electric ignition system. Most newer gas ranges and ovens don't have pilot lights. Connect the new switch the same way the old one was connected. Remove the switch and replace it with a new one of the same type. If the meter reads higher than zero, the switch is faulty and should be replaced. If the switch is functioning, the meter will register zero. Clip one probe of the VOM to each switch terminal. Remove the retaining screws that hold the switch in the range cabinet, and disconnect both electrical lead wires to the switch. Turn off the power to the range and test the switch with a volt-ohm-milliammeter (VOM) set to the RX1 scale. If the pilot has a switch, the switch may be faulty. After cleaning the tube, replace it in the same position. You may have to disconnect the tube to clear it. Push the wire through the opening until the tube is clear. If this is the case, turn off the power to the range and clean out the tubes using a short piece of wire. These tubes may be blocked by spilled food from the burners. If the pilot flame is properly adjusted, but the flame doesn't ignite the burners, the problem is probably in the flash tubes that run from the pilot to the burners. Most modern gas ranges use an electronic pilot igniter to start the pilot. To correct either condition, turn the pilot adjustment screw on the gas line slightly, as directed by the manufacturer of the range. If there's a space between the flame and the pilot feed tube, it's getting too much air. If the flame goes out repeatedly, or if it's yellow at the tip, it's getting too little air. A correctly adjusted pilot flame is steady and blue, between 1/4 and 1/2 inch high. Some ranges have two pilot lights, one for each side of the range. One pilot light usually serves all the top burners of a gas range.
