Whirlpool Oven Spark Module Replacement — What This Part Does
The spark module is a high-voltage control board mounted behind the rear access panel or under the cooktop. It generates and routes ignition sparks to the bake, broil, or surface-burner electrodes whenever you command ignition. The module receives a signal from the main control, then fires a high-voltage arc across the electrode gap to light the gas.
Modules fail from repeated high-voltage cycling, moisture intrusion, grease contamination, or thermal stress in the oven cavity. Burned terminals, cracked solder joints, and component fatigue inside the board all stop spark generation. Because Whirlpool uses different module designs across model families, the exact failure mode varies but the root cause is usually the board itself once wiring and electrodes are ruled out.
Signs It Needs Replacing
- No clicking sound when you try to ignite The module stays silent and produces no spark at any burner or oven igniter.
- Burners only light when you hold a lighter to them Gas flows but the spark module never fires, forcing manual ignition.
- Intermittent or weak spark The module clicks sometimes but the arc is inconsistent or stops mid-cycle.
- Spark at the wrong burner Turning on one burner produces spark at a different location, indicating module miswiring or internal board crossover.
- Continuous clicking with no ignition The module sparks endlessly but the burner never lights, often paired with a cracked electrode or grounded spark path.
- Burn marks or melted connectors on the module Visible damage at the board terminals or wire spades shows the module has shorted or overheated.
How to Replace It
- Unplug the range from the wall receptacle or shut off the dedicated circuit breaker, then turn off the gas supply valve upstream of the appliance.
- Remove oven racks and any rear or bottom access panels to reach the spark module (on ranges, it is typically behind the rear guard or under the cooktop surface).
- Take a photo or sketch of every wire connector and terminal position on the module before you disconnect anything.
- Pull each spade connector or harness plug straight off the module terminals, noting any labeling or color codes on the wires.
- Unbolt or unscrew the old spark module from its mounting bracket and lift it clear of the chassis.
- Position the new Whirlpool OEM spark module on the same mounting holes and secure it with the original screws.
- Reconnect every wire harness and spade terminal to the exact same posts on the new module, verifying that each connector seats fully and matches your photo.
- Reinstall all access panels, oven racks, grates, and burner caps, then restore electrical power and turn the gas supply valve back on.
- Command ignition at each burner or oven function and confirm you hear clicking and see spark at the correct electrode before closing up the appliance completely.
The Part You Need
| Part | Notes |
|---|---|
| Whirlpool range spark module | Amazon | Find your exact model and serial number on the metal tag inside the oven door frame or on the rear panel. Cross-reference that number on the Whirlpool parts site or at an authorized dealer to pull the correct module (common OEM numbers include WPW10475149, WPW10511278, and WP8053421, but fitment varies by model family). |

When to Call a Pro
If you are uncomfortable working around both gas supply lines and live electrical connections, hire a qualified appliance technician. Any gas leak, improper electrode alignment, or miswired spark-module terminal can create an ignition hazard or prevent safe burner operation. Professionals also carry multimeters and high-voltage testers to confirm whether the fault is truly the module or a downstream electrode, wiring short, or main-control signal problem. For built-in ranges or units with complex manifold access, professional disassembly prevents cabinet damage and ensures gas fittings are torqued and leak-checked correctly. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
