Operating Instructions
The Frigidaire 318004900 Range Switch is an infinite switch designed to regulate the heat output of a surface burner on your range. Once installed, its operation is integrated with your appliance's control knob. Turning the control knob will send varying levels of power to the burner, allowing you to select the desired heat setting from low to high.
- Ensure the control knob is properly seated on the switch shaft.
- Rotate the knob to the desired heat setting. The switch will then regulate power to the burner.
- Turn the knob to the 'OFF' position when cooking is complete.
Maintenance
The Frigidaire 318004900 Range Switch is a sealed component and does not require routine maintenance. However, periodic inspection of the wiring connections can help ensure continued safe operation.
- Annual Inspection: With power disconnected, visually inspect the wiring connected to the switch for any signs of wear, fraying, or loose connections.
- Cleaning: If the area around the switch becomes dirty, ensure power is disconnected and gently clean with a dry cloth. Avoid using liquids near electrical components.
Troubleshooting
If you experience issues after replacing the range switch, consider the following:
- Burner Not Heating:
- Check if the circuit breaker for the range is tripped.
- Verify all wires are securely connected to the switch and the burner element.
- Ensure the control knob is correctly aligned and engaging the switch shaft.
- Burner Only Heats on High/Low:
- This could indicate a faulty switch or incorrect wiring. Re-check wiring against your diagram.
- Sparking or Burning Smell:
- Immediately disconnect power to the appliance. This indicates a serious electrical issue. Do not restore power until the problem is identified and corrected by a qualified technician.
If troubleshooting steps do not resolve the issue, contact a qualified appliance repair technician.
