Check that the stove top is plugged into a working electrical outlet if the ignitors fail to spark and the burners fail to ignite. If the plug is firmly in place, check the circuit breakers or fuses. Reset any breakers that have tripped and replace any fuses that have burned out.
Unplug your stove from the power outlet so there is no risk of shock during the repair process. Remove the grilles from the stove top to access the burners beneath. Grab the burner with your hand and lift it off of the stove. The burner ends may have metal tabs that must be slid out of their notches in the stove top before they will release fully.
Take out the protective metal shield from the stove top to access the ignitor beneath. Locate the set screws that hold the shield in place and use a screwdriver to remove them. Locate the ignitor switch then use a small flat head screwdriver to release the power wires from it. Press the blade of the screwdriver into the slots next to each wire until the wire loosens and releases.
Replace the existing switch with a new one with the same specifications. If the ignitor still fails to spark, test the ignitor control module. Make your kitchen as dark as possible then turn each burner to the start position, one at a time. Watch for sparks from each burner. If any of the ignitors fails to spark, the control module will have to be replaced.
Follow the wires that run to the ignitor switch. They should lead to a small plastic box that houses the control module. Use a screwdriver to remove the module from the surface of the stove and replace it with a new one of the same specifications. Transfer one wire at a time from the old module to the new one to avoid installation errors. Mount the new module in place and test the burners again.
Things You Will Need
- Screwdriver set
- Replacement ignitor switch
- Replacement ignitor control module
- Stiff wire
- All purpose cleaner
- To test if your ignitor switch has gone bad, turn on a working burner and leave the knob set to the "Light" position. Turn the knob of the non-functioning burner to the "Light" position as well. If the non-functioning burner now ignites, the ignitor switch is bad.
- Dirty burners can also cause a stove top to fail to light. Clean out the tiny holes along the sides of the burners with a piece of stiff wire and all purpose cleaner then test the burner again.
