I turn the knob on the front right burner and nothing... I turn any other knob and all ingitors spark... Maybe in the pot behind the knob??Frigidaire Gas range. Model 316 (I think) I'm getting gas and spark just not when i turn that specific knob

Behind the knobs for the right burners are 2 electrical switches that start the spark when you turn the knobs on. One of those switches is bad and stuck in the on position. You have to pull the knobs off and remove the trim behind the knobs to get to the switches.

It'll be a switch problem on the valve in question.

If there is no clicking sound like you hear when you turn on the other burners than I'm going to say that either the electrode is bad or the spark switch, which is what you turn to turn on the burner to begin with. Both parts are cheap so it may be a good maintenance thing to change all of the burners. Make sure you have your model and go to www.repairclinic.com and order both parts, and if you don't need one send it back for a full refund even if you installed it. good luck

One of them spark switch's is shorted. You must remove one at a time till you find that bad boy. OR replace the harness.

Most of these have a switch behind each knob that triggers the spark.

OFTEN during cleaning, mositure gets into the switch causing the problem.

If you suspect this, try using a hair drier to dry out behind the knob if you can;t remove and investigate if this could be the cause.

it is strange that you have no gas and no spark! if you held a match to the burner and turned the burner valve on it would lite di spite a failed ignitor,but for it not to lite, the burner valve[its what the knob attaches too] would have to be blocked[thats rare]or ........i got it .....the knob is broken.thats the only thing the burner valve and the spark ignitor have in common.try a knob from another burner................again.you have spark,because others are working.spark on troubled burner would work if valve blocked at orifice outlet,and if spark failed you would still get gas they work independent of each other,[but in unison].thats why im thinking knob.its the item that works both .when you turn the knob it opens the gas valve and as the gas valve rotates by turning the knob it activates or turns the spark switch so it closes the curcit allowing the electricty to the spark moduel.hey i hope that helps a little. God bless ,tom

You have one or more spark switches defective or a loose wire to the switches.
They are located on each gas valve stem.
Yes they should be replaced for safety.
In the interim you can match light the surface burners.

behind the knobs you will find the switches that makes them ignite ,it they are wet they will try to ignite by then self. make sure they are dry.

The switch probably failed. Remove power. Take off the top rear cover and inspect the switch for signs of discoloration (burned or brown areas). If looks OK then maybe the element failed.
