If your Frigidaire electric range isn’t working properly, a faulty wiring harness could be the problem. Damaged wires or poor connections can cause power issues, making it necessary to replace the entire harness.
Common Signs of Wiring Harness Failure
A faulty wiring harness can cause various performance issues in your range. Here are some common signs that indicate it might need to be replaced:
- Inconsistent Heating: If the oven or burners are not heating evenly or turn off unexpectedly, a damaged wiring harness may be causing power interruptions.
- Burnt Smell or Visible Damage: A burnt plastic smell or visible charring on wires is a strong indicator of electrical failure.
- Control Panel Malfunctions: If the oven display, buttons, or controls become unresponsive, the wiring harness could interfere with the electrical signals.
- Frequent Tripping of Circuit Breaker: A short circuit within the harness can cause the breaker to trip repeatedly.
- Sparking or Arcing: Any visible sparks when the appliance is in use suggest a serious wiring problem that needs immediate attention.
- Loose or Disconnected Wires: If wires frequently come loose, connections may no longer be secure due to wear or corrosion.
When to Replace the Wiring Harness
The wiring harness connects various electrical components in your range. Instead of attempting to repair individual wires, replacing the whole harness is often the best solution. Here are some common reasons for replacement:
- Damaged Wires: Frayed, burnt, or broken wires can lead to shorts, power loss, or arcing, often caused by heat exposure or wear over time.
- Corroded or Loose Connectors: If the connectors that attach to components like the oven control board or surface element switches are corroded, melted, or loose, they can disrupt electrical connections.
- Replacing the Oven Control Board: When installing a new control board, replacing the wiring harness helps maintain proper fit and reliable connections.
Tools and Parts Needed
- 1/4-inch nut driver
- Replacement wiring harness (make sure it’s compatible with your specific model)
Safety Precautions
Working with electrical appliances requires caution. Follow these steps to stay safe:
- Power Down First: Unplug the appliance or turn off the circuit breaker before starting any work to prevent electrical shock.
- Let It Cool – If the range was recently in use, allow enough time for it to cool before handling any parts.
- Take Your Time: Rushing through the process increases the risk of mistakes and injury.
- Work in a Well-Lit Area: Proper lighting makes it easier to see and access internal components.
- Keep the Space Clear: Remove any clutter or obstacles to create a safe workspace. Keep pets and children away.
- Ensure Dry Hands and Surface: Never handle electrical parts with wet hands or in a damp area.
- Follow the User Manual: Review your appliance’s manual for specific installation instructions and safety guidelines.
- Use Gentle Handling: Applying excessive force when removing or installing parts can cause damage or injury.
- Wear Protective Gear: Insulated gloves protect against sharp edges and electrical exposure. Safety glasses and a dust mask can be useful when working with debris or chemicals.
How to Replace the Wire Harness in a Frigidaire Electric Range
Here are the steps to remove the old wire harness and install the new one.
- Turn off the range and unplug it from the outlet.
- Use a 1/4-inch nut driver to remove the 1/4-inch screws along the sides of the back oven cover.
- Remove the back oven cover and set it aside.
- Use the 1/4-inch nut driver to remove the 1/4-inch screws along the sides of the back console cover.
- Remove the back console cover and set it aside.
- Start at the top of the range and disconnect one wire from the original harness.
- Immediately connect the corresponding wire from the new harness.
- Continue working downward, replacing each wire one by one.
- Position the back oven cover back onto the range.
- Secure the back oven cover using the 1/4-inch screws.
- Position the back console cover back onto the range.
- Secure the back console cover using the 1/4-inch screws.
- Plug the range back in.
- Turn the range on.
- Run a short test cycle to confirm the range is working properly.
Preventing Wiring Harness Damage
Extending the lifespan of your wiring harness can save you from frequent replacements. Here are some maintenance tips:
- Inspect Wires Regularly: Look for signs of wear, corrosion, or fraying before they cause major issues.
- Avoid Excessive Heat Exposure: Make sure the range’s ventilation system is working properly to prevent overheating.
- Keep Connectors Secure: Loose connections can cause arcing and short circuits, so check that connectors remain properly attached.
- Use Surge Protection: A surge protector or voltage stabilizer can prevent electrical spikes from damaging the internal wiring.
- Clean with Care: Avoid using excessive water or cleaning solutions near electrical components.
- Replace Faulty Components Promptly: If a switch, control board, or heating element fails, replace it before it affects other parts.

Key Takeaways
A broken wiring harness can cause all sorts of problems with your Frigidaire electric range, but swapping it out is easier than it seems. With basic tools and careful steps, you can get your oven running smoothly again.
Ignoring electrical problems can lead to worse issues: burnt wires, unexpected shutdowns, or even safety risks. If you notice a burning smell or your breaker keeps tripping, it’s time to take action. Follow each step closely, work safely, and check all connections before turning the power back on.
Regular maintenance helps prevent future breakdowns. Keep an eye on your wiring, make sure connections stay tight, and avoid excessive heat buildup.
