Frigidaire Range Spark Igniter Clicking After Burner... | appliancefaults.com

Technical Background:

The range's main control unit (MCU) sends a signal to the spark module when a burner knob is turned on. The spark module generates high-voltage pulses that travel to the spark igniter near the burner. These pulses create a spark that ignites the gas. Once the flame sensor detects a flame, the MCU should stop sending the signal to the spark module. If the flame sensor fails or the MCU malfunctions, the spark module may continue to receive the signal, causing continuous sparking.

Symptoms:

The spark igniter on a Frigidaire range continues to click repeatedly even after the burner flame is established and stable. This can be noisy and indicate a problem with the ignition system.

Possible Causes:

Dirty or Wet Burner Ports
Faulty Spark Module
Incorrect Grounding
Defective Spark Igniter
Shorted Wiring Harness

Solution:

1

Disconnect power to the range at the breaker panel.
2

Remove the burner grates and burner caps.
3

Clean the burner ports with a small brush or wire. Ensure they are free of debris and dry.
4

Inspect the spark igniter for cracks or damage. If damaged, replace it. Using a 1/4-inch nut driver, carefully remove the igniter mounting screws.
5

Use a multimeter to check the spark module for proper voltage output (typically around 3-4 kV AC). If there is no output, replace the spark module. Use insulated pliers to disconnect the high-voltage wires.
6

Inspect the wiring harness for any shorts or damage. Repair or replace as needed. Use electrical tape to insulate any exposed wires.
7

Verify the range is properly grounded. Check the grounding wire connection at the back of the range and at the outlet using a multimeter in continuity mode.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Lock out/tag out (LOTO) the breaker to prevent accidental energization. Be aware of high voltage present at the spark module.

Prevention:

Regularly clean the burner caps and burner ports to prevent grease and food buildup. Avoid spilling liquids near the burners. Periodically inspect the spark igniters and wiring for any signs of damage.

Expert Tip:

Some Frigidaire ranges have a diagnostic mode that can be accessed by pressing and holding specific buttons. Refer to the service manual for the specific sequence. This mode may display error codes related to the ignition system.

Frequently Asked Questions

•How do I test the flame sensor on my Frigidaire range?

Use a multimeter to check the flame sensor's resistance when the burner is lit. A good flame sensor should have a low resistance (typically under 100 ohms). If the resistance is high or infinite, the flame sensor is likely faulty and needs replacement.

•Where can I find the spark module on my Frigidaire range?

The spark module is typically located behind the control panel or near the back of the range. You may need to remove the back panel to access it. Refer to the range's service manual or parts diagram for the exact location.

•What voltage should I expect to see at the outlet powering the range?

A standard US range outlet should provide 120V AC for the electronics and 240V AC for the heating elements. Use a multimeter to verify that the outlet is providing the correct voltage.
