Gas stove burners that keep clicking even after they ignite can be frustrating. It’s not just annoying; it can also be a sign of an internal electrical issue. When the clicking won’t stop, even when the flame is steady, the spark module often becomes the prime suspect. This post covers what happens inside that component, why it fails, and how to handle the repair safely. For anyone handling appliance repair in Edmonton, understanding this issue can save time and money.
What the Spark Module Actually Does
Every time we turn on a burner, the spark module sends a high-voltage pulse to create a spark at the burner head. That pulse is what lights the gas. The module receives a signal from the control knob and responds by firing off a rapid clicking burst. Once the flame lights, the signal stops, and the clicking ends.
However, a damaged spark module may continue sending voltage even after ignition. This makes the burner keep clicking for no reason. A faulty ground or internal short in the module can also make all burners click at once, even when only one is being used.
This electrical part is designed to stay sealed. Therefore, it’s not serviceable internally. If we confirm that it’s the issue, the whole spark module needs replacing.
Signs the Spark Module Is the Problem
Sometimes it’s not clear what’s actually causing the continuous clicking. Moisture or food debris in the igniter cap can also create this effect. However, several specific signs usually point back to the spark module itself.
Firstly, all burners click even when only one knob is turned. Secondly, the clicking continues after ignition and doesn’t stop unless the appliance is unplugged. Third, there’s a faint burning smell near the module’s housing, or we hear irregular clicking patterns. In these cases, replacing the spark module often solves the issue.
In situations where the stove clicks randomly when no one is around, voltage leakage inside the module may be responsible. For complex or persistent issues like these, professional stove repair in Edmonton is often necessary.
How to Safely Test the Spark Module Voltage Output
Testing the module requires care, since it involves high-voltage discharge. We never touch the terminals directly. Instead, we use a multimeter or spark tester tool and follow safety steps strictly.
First, disconnect the stove from power to prevent electric shock. Then remove the back panel or burner cover where the module is located. We check for any visible signs of damage or burnt wiring. If we see melted insulation or blackened components, the module is likely the issue.
Next, we set the multimeter to AC voltage and place the probes on the module output leads. When power is restored and a burner is turned on, a healthy module should generate between 2,000 and 3,500 volts. If there’s no output or the voltage is erratic, the module needs replacing.
Never try to test this part without the right equipment. If unsure, we always recommend using certified appliance repair in Edmonton to keep things safe.
Replacing the Faulty Spark Module
Once we confirm the module has failed, the replacement process is straightforward but must be done precisely. We disconnect all power and remove the back panel again. The module is usually held by two or more screws and connected by a wire harness.
Before disconnecting anything, we take a clear photo of the wiring. This helps when reconnecting the new module. We remove the old one, swap it for the new unit, and reattach all wires securely. It’s important to make sure each terminal goes to the correct pin to prevent future problems.
After installing the new module, we reassemble the stove and test each burner. If the clicking stops once the flame lights, then the fix worked. If not, there may be another issue like a failed ignition switch or misaligned igniter head.
In some cases, people notice moisture near the burner even after replacing the part. This points to a separate issue unrelated to the spark module and needs further diagnosis.
Other Causes That Mimic Spark Module Failure
While the spark module is often to blame, there are other parts that can mimic the same symptom. A faulty ignition switch stuck in the “on” position can send continuous signals to the module. If only one burner clicks endlessly, we check the switch behind that burner knob.
Also, a clogged igniter or wet spark electrode can create constant clicking. If we recently cleaned the stove or had a spill, drying the burner heads and igniter with a fan or paper towel may fix the problem.
These checks help us avoid unnecessary replacements. If the issue continues despite trying all the above, it’s time to contact a technician through the appliance repair contact line for further help.
Preventing Spark Module Issues in the Future
Once the spark module has been replaced, we want it to last. Most issues stem from moisture, grease, or accidental spills. Wiping up food before it settles and avoiding excess water around the knobs can prevent premature failure.
We also recommend checking the burner caps after every cleaning. Misaligned caps can confuse the spark system and trigger ongoing clicks. Always make sure the burner is dry, level, and seated properly before lighting it again.
Using the stove with a vent hood can reduce humidity that affects the module. And when cleaning, we avoid spraying directly onto the control knobs. A cloth dampened with mild cleaner is safer.
These steps help prevent more electrical issues and reduce the chance of another service call for stove burner clicking problems.
Frequently Asked Questions
Why do all burners click even when only one is on?
This usually points to a faulty spark module or a shared ignition switch sending signals to all electrodes.
Is it safe to use the stove when it keeps clicking?
It’s best to unplug the stove and avoid using it. Continuous voltage from a faulty spark module can wear out other parts.
How do I dry out a wet spark igniter?
Turn off the stove and unplug it. Use a paper towel or fan to air-dry the area for several hours.
What tool checks spark module voltage?
We use a multimeter with AC setting or a high-voltage spark tester. Testing must be done carefully to avoid electric shock.
Can a faulty burner switch cause constant clicking?
Yes, if the switch is stuck in the “closed” position, it may keep signaling the module even after ignition.
