If your Frigidaire upright freezer is experiencing issues, the compressor start relay might be the problem. This guide will help you test and, if needed, replace the relay without requiring a costly service visit.

Tools You’ll Need

  • Multimeter
  • Needle-nose pliers

Safety First

When working on appliances, safety is essential. Follow these precautions to protect yourself and your equipment:

  1. Disconnect Power: Unplug the freezer or turn off the circuit breaker before starting any work. This step eliminates the risk of electric shock.
  2. Allow Cooling Time: If the freezer has been in use, let it cool down completely before handling any components.
  3. Organize Your Workspace: Work in a clean, well-lit area free from clutter. Keep children and pets out of the vicinity.
  4. Dry Conditions: Keep your hands and workspace dry to reduce the risk of electrical shock.
  5. Handle with Care: Be gentle when removing or handling parts to avoid damaging the appliance.
  6. Wear Protective Gear: Use insulated gloves to protect your hands from sharp edges and electrical components. Safety glasses or a dust mask are helpful when dealing with debris or chemicals.
  7. Document Connections: Take photos or make notes of wiring connections before disconnecting anything to make reassembly easier.
  8. Avoid Live Testing: If you’re unfamiliar with safe practices for live voltage testing, avoid it to prevent accidents.
  9. Check the Manual: Refer to the freezer’s user manual for any specific instructions or warnings related to your appliance or the replacement part.

How to Test and Replace a Compressor Start Relay

Follow these steps to check if the compressor start relay is functioning properly and replace it if necessary.

Test the Compressor Start Relay

  1. Pull the freezer out from the wall to access the compressor area.
  2. Plug the freezer into a power outlet and verify it is powered on.
  3. Set the multimeter to measure AC voltage.
  4. Place the multimeter probes on the yellow wire connected to the start relay.
  5. Read the multimeter display. If it shows 120 VAC, the start relay needs to be replaced.

Replace the Compressor Start Relay

  1. Unplug the freezer from the power outlet.
  2. Disconnect the single connector attached to the start relay.
  3. Use needle-nose pliers to remove the wire clip securing the relay.
  4. Gently move the relay side-to-side to detach it from the compressor.
  5. If a run capacitor is attached to the old relay, transfer it to the new relay.
  6. Position the new relay on the compressor and secure it with the wire clip.
  7. Reconnect the wire connector to the new relay.
  8. Plug the freezer back in or switch the circuit breaker back on.

Benefits of Replacing the Start Relay Promptly

Delaying the replacement of a faulty start relay can cause further damage to the freezer or increase energy consumption. Addressing the issue promptly provides several advantages:

  • Improved Cooling Performance: A functional relay allows the compressor to operate efficiently, restoring optimal cooling.
  • Extended Appliance Lifespan: Replacing worn-out parts reduces strain on the compressor and prevents additional wear and tear.
  • Reduced Energy Costs: A properly working relay prevents the compressor from overworking, lowering electricity usage.
  • Prevention of Food Spoilage: Prompt repairs help maintain consistent freezer temperatures, protecting stored food from spoilage.
  • Avoidance of Major Repairs: Timely replacement prevents potential damage to the compressor, which is expensive to fix or replace.

Tips for Maintaining the Compressor Start Relay

Preventive care can help you avoid future issues with the compressor start relay. Follow these maintenance practices:

  • Keep the Freezer Clean: Dust and debris around the compressor area can cause overheating. Regularly clean the back of the freezer and around the vents.
  • Monitor Electrical Connections: Check the wires and connections periodically for signs of wear or damage, such as fraying or corrosion.
  • Avoid Overloading the Freezer: Too much weight or overstuffing the freezer can strain the compressor and related components, including the start relay.
  • Inspect for Unusual Noises: Address any unusual sounds promptly, as they may indicate wear or damage to internal components.
  • Schedule Regular Checks: Make it a habit to inspect the freezer’s performance every few months, looking for signs of inefficient cooling or electrical issues.
