4. Installation Instructions

This section outlines the general procedure for replacing a dryer terminal block. Specific steps may vary slightly depending on your dryer model. Refer to your dryer's service manual for detailed instructions.

Required Tools:

• Screwdriver (Phillips head typically)
• Work gloves

Procedure:

1. Disconnect Power: Before beginning any work, ensure the dryer is completely unplugged from the electrical outlet. Turn off the circuit breaker supplying power to the dryer for added safety.
2. Access the Terminal Block: Locate the access panel on the back of your dryer where the power cord connects. This panel is usually secured by screws. Remove the screws and the panel to expose the terminal block.
3. Document Wiring: Before disconnecting any wires, take a clear photograph or make a diagram of how the existing wires are connected to the old terminal block. This will be crucial for correct reassembly.
4. Disconnect Wires: Carefully loosen the screws on the old terminal block and disconnect the household electrical power wires (typically three or four wires: two hot, one neutral, and sometimes a ground) and the dryer wiring harness wires.
5. Remove Old Terminal Block: Unscrew and remove the old terminal block from its mounting location. There are typically two screws securing the block itself.
6. Install New Terminal Block: Position the new Whirlpool 3397659 terminal block in place and secure it with the mounting screws.

8. Replace Access Panel: Reattach the access panel on the back of the dryer, securing it with its screws.
9. Restore Power: Plug the dryer back into the electrical outlet and turn on the circuit breaker.
10. Test Operation: Run a short cycle on the dryer to confirm proper operation.

5. Operation

The Whirlpool 3397659 Terminal Block is a passive electrical component. Once correctly installed, it facilitates the safe and continuous flow of electricity from your household power supply to the dryer's internal components. It does not require any user interaction or operational steps after installation. The dryer's normal operation will proceed as designed.

6. Maintenance

The terminal block itself requires minimal maintenance. However, periodic inspection is recommended to ensure continued safe operation:

• Visual Inspection: Approximately once a year, or if you notice any unusual odors or performance issues from your dryer, unplug the dryer and remove the access panel. Visually inspect the terminal block and its connections for any signs of discoloration, melting, charring, or loose wires.
• Tighten Connections: If any wires appear loose, carefully tighten the terminal screws after ensuring the dryer is unplugged.
• Replace if Damaged: If the terminal block shows any signs of damage, such as cracks, melting, or severe discoloration, it must be replaced immediately to prevent electrical hazards.

7. Troubleshooting

Issues related to the terminal block often manifest as a complete lack of power to the dryer or intermittent power problems. If your dryer is experiencing electrical issues, consider the following:

• No Power: If the dryer receives no power, first check the circuit breaker and the wall outlet. If these are functioning, the terminal block or its connections might be faulty.
• Burning Smell or Discoloration: A burning smell, visible charring, or melted plastic around the terminal block indicates a severe electrical issue, likely due to loose connections or an overloaded circuit. Immediately unplug the dryer and do not use it until the terminal block is inspected and replaced if necessary.
• Intermittent Power: Loose connections at the terminal block can cause the dryer to lose power intermittently.

Important: Electrical troubleshooting can be dangerous. If you are not comfortable performing these checks, contact a certified appliance technician.
