If your Frigidaire electric range is showing error codes, failing to heat properly, or has a non-responsive control panel, the main control board may be the issue. Replacing it is a straightforward repair that can restore your range’s functionality and help you avoid costly service fees.
Signs the Control Board Needs Replacement
A faulty control board can cause a range of issues, from heating problems to a completely unresponsive display. Here are some signs that indicate it might need to be replaced:
- The oven doesn’t heat or has inconsistent temperatures.
- The display panel is blank, scrambled, or unresponsive.
- The self-cleaning function no longer works.
- Error codes indicate a control board failure.
- The board has visible burn marks, or its ribbon cables are damaged, especially after power surges.
Common Causes of Control Board Failure
Several factors can cause a control board to stop working, some of which can be prevented with proper care.
- Power Surges and Outages: Sudden electrical spikes can burn out circuits or damage ribbon cables.
- Moisture Exposure: Steam, spills, or high humidity can cause corrosion and short circuits.
- Wear and Tear: Over time, repeated use and heat cycles can degrade the board’s components.
- Improper Installation: Incorrect wiring or using a non-compatible board can cause failure.
- Manufacturing Defects: Some boards may develop faults due to design flaws or poor-quality components.
Tools and Materials Needed
- 1/4-inch nut driver
- Phillips screwdriver
- Replacement control board (make sure it works with your range model)
Safety Precautions
Before starting any repair, follow these safety guidelines:
- Disconnect Power: Unplug the range or turn off the circuit breaker to prevent electric shock.
- Allow Cooling Time: If the appliance was recently in use, wait for it to cool completely before working on it.
- Work in a Safe Environment: Use good lighting, keep the area clear of clutter, and keep pets and children away.
- Avoid Moisture: Keep hands and the workspace dry when handling electrical components.
- Follow Manufacturer Guidelines: Check the user manual for any model-specific instructions.
- Handle Parts Carefully: Avoid excessive force, which could damage components or cause injury.
- Use Protective Gear: Wear insulated gloves to protect against sharp edges and safety glasses if dealing with dust or debris.
- Exercise Caution with Wires: Avoid touching exposed wires or terminals. Use a non-conductive tool if necessary.
