Dacor Gas stove burners spark all the time
If your Dacor gas stove igniter keeps clicking or the gas stove keeps sparking after the burner lights, a defective spark ignition switch is the most likely cause. A switch with contacts stuck closed can continuously send voltage to the spark module, so test each switch with a multimeter and replace any switch that shows continuity at every setting. A wet or shorted spark ignition switch and harness is the next common cause, especially after a boil-over. Unplug the range and let the stovetop dry completely before testing or replacing the switch. If the switches check out, inspect the surface burner orifice holder. A misaligned holder may not ground properly, preventing the flame-sensing circuit from stopping the spark. A burner cap that is not seated correctly can also keep a burner from lighting properly, causing the burner to keep sparking. Finally, inspect the spark electrode for dirt or visible damage, since a faulty electrode may not let the spark module sense the flame. Turn off power and gas before servicing your Dacor range. Enter your model number to find the exact spark ignition switch, harness, or other replacement part for your specific gas stove.
01 - Dacor Range/Stove/Oven Spark Ignition Switch
One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the spark ignition switch fails with the electrical contacts closed, the switch will send continuous voltage to the spark module. To determine if any of the spark ignition switches is defective, use a multimeter to test each of the switches for continuity. If a spark ignition switches shows continuity at all settings, replace it.

02 - Dacor Range/Stove/Oven Spark Ignition Switch and Harness
One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the switch contacts are wet or stuck in a closed position, the switch will send continuous voltage to the spark module, no matter where the dial is set. Each of the switches can be tested individually to determine if they are shorted. If a spark ignition switch is shorted and is not wet, or if drying it out doesn’t solve the problem, replace the switch.

03 - Dacor Range/Stove/Oven Surface Burner Orifice Holder
Some burners have a flame sensing circuit that sense the burner flame through the spark electrode circuit. If the burner has a good flame but the igniter keeps sparking the orifice holder may not be damaged and not grounding properly. Inspect the holder to see if it's misaligned and replace with a new one as required.

04 - Burner cap not on properly
On some models the spark module will automatically shut off the spark when the burner lights. If the burner cap is not on properly the gas or flame may not get to the igniter causing continuous sparking. Confirm the appliance is turned off and the stovetop is cool to the touch, then readjust the burner cap, if necessary, so it is seated properly on the burner base.

05 - Water spilt on switches
The spark switches under the burner knobs have to be dry to work properly. If water boils over or is spilt on the spark switches, they can short out, causing the burners to spark even when the switch is turned off. The range should be unplugged and the stovetop allowed a day to dry out.
Common
06 - Dacor Range/Stove/Oven Spark Electrode
The range's spark module sends pulses to each spark electrode to create a spark to ignite the gas. If the spark module has a flame sensing function it will automatically stop sending pulses to the electrode when the burner lights. If the electrode is defective the spark module will not be able to sense the flame and continue to allow the electrode to spark after the flame has ignited. Inspect the electrode to see if it's visibly damaged or dirty and replace if necessary.
