Gas Oven: Pilot Lights, Shutoff Valves, and Ignition Systems
The fire of gas range burners should be steady and slightly rounded , with a light - blue backsheesh . The flaming should be still and should respond to adjustment made at the dominance knobs . Most burner troubles can be quick solve by adjust the air shutter mixer plate , which is located at the end of the burner tube near the pommel restraint . grow a small shag on the collection plate , slide the crustal plate candid or closed , and tighten up the setscrew .
If the flame is yellow , it ’s not receiving enough atmosphere . To allow more air in , open up the plate more or less . If the fire is high or crap a prosperous noise , it ’s getting too much melody and you should end the plate somewhat .
Servicing Pilot Lights
One pilot light commonly serve all the top burners of a gas pedal reach . Some ranges have two pilot film light , one for each side of the range . A correctly adjusted pilot film fire is firm and blue , between 1/4 and 1/2 column inch high . If the fire get out repeatedly , or if it ’s yellow at the tip , it ’s getting too trivial air . If there ’s a space between the flaming and the pilot provender tube , it ’s getting too much air . To adjust either condition , turn the pilot readjustment screw on the petrol line slimly , as directed by the manufacturer of the range .
Most modern gaseous state ranges use an electronic fender igniter to start the pilot .
If the pilot flame is decently adjusted , but the flame does n’t ignite the burners , the trouble is plausibly in the flashgun tubes that run from the pilot to the burners . These thermionic valve may be halt by spilled food from the burner . If this is the event , turn off the power to the range and clean out the tubes using a short objet d’art of telegram . Push the wire through the opening until the thermionic vacuum tube is clear . You may have to unplug the tube to acquit it . After clean the tube , replace it in the same spatial relation .
If the pilot has a switch , the electric switch may be incorrect . release off the power to the range and try the switch with a volt - ohm - milliammeter ( VOM ) fix to the RX1 scale . Remove the retaining screws that nurse the switch in the range cabinet , and unplug both electric track wires to the switch . snip one probe of the VOM to each switch terminal . If the switch is operate , the metre will register zero . If the meter understand higher than zero , the substitution is faulty and should be replaced . polish off the switch and replace it with a new one of the same type . tie the new permutation the same mode the old one was connected .
Most newer gas mountain range and ovens do n’t have pilot lights . rather , the accelerator pedal is erupt by an galvanizing ignition system arrangement . In this type of system , an chemical element becomes blistering and glows like the filament in a lightbulb when an electric current passes through it . The heat from the filament alight the gasoline . As a rule , these ignition systems are sealed and can not be repaired or adapt . When an electric kindling equipment fails , do n’t seek to fix it . Call a professional service person for substitute .
If the flame is set too low , adjust it . Next to the pilot , locate a small boxy building block with a couple of screws in it . This is the ignition unit . The ignition unit could also be located below the pilot program ; follow the gas line down until you place it . move around one of the roll in the hay on the ignition . Experiment , turning the screw a little at a time , until the flame is set properly . It should not be as eminent as the top archetype flame ; result it as low as potential . On some oven pilots , turn the control to the OFF situation and light the pilot film ; then bend the oven dial to the BROIL placement . The pilot will inflame the control to the ignition system switch .
Servicing Automatic Shutoff Valves
On some mountain range , there is an automatic shutoff valve located in the original assembly that shuts off the accelerator to the burner any time the pilot and the burner are both off . If this unit malfunctions , do n’t seek to fix it yourself ; you should call a professional inspection and repair someone for reparation or replacement . An electrically operated shutoff valve used on some gas ranges has two facing valves , an electromagnet , and a manually activated reset button . The thermocouple fitting is next to the fender valve , as in most burner system of rules . A modest amount of electricity holds the face valve aside . If the airplane pilot light lead out , no electrical energy is generated , and the valve closes to turn the gas off . On this type of system , relight the pilot by depressing the reset button and holding a match to the airplane pilot . It should take about a minute to light this airplane pilot . If you are n’t able to relight this system , call a professional service mortal . galvanising ovens and range are maturate in popularity , probably because most repairs demand just replacing a worn or wrong part .
