How to change the start button on my Whirlpool dryer model #LER7646EQ0, serial #MF478917?

Replacing the start button on your Whirlpool dryer model LER7646EQ0 is a straightforward process that can be completed with basic tools and a few careful steps. If the start button is malfunctioning or damaged and needs replacement, follow these instructions:

1. Safety Precautions:
Safety is a top priority when working with electrical appliances. Before you begin, unplug the dryer from the electrical outlet or turn off the circuit breaker that supplies power to it. This will prevent any electrical accidents while working on the appliance.
2. Gather Tools and Materials:
You'll need a few tools and materials for this task, including a screwdriver (usually a Phillips or flathead), pliers, a small bowl or container for storing screws and small parts, and a replacement start button compatible with your Whirlpool dryer model LER7646EQ0.
3. Access the Control Panel:
To access the start button, you'll need to open the control panel of your dryer. This usually involves removing the top or front panel, depending on the dryer's design. Refer to your dryer's user manual or service manual for specific instructions on panel removal.
4. Remove the Control Panel Cover:
If you need to remove the entire control panel, locate the screws securing it to the dryer's frame. Use the appropriate screwdriver to remove these screws, and place them in the container for safekeeping.
5. Disconnect Wiring:
After removing the control panel cover, you'll see the start button assembly. It will have wires connected to it. Carefully disconnect these wires by gently pulling them off the terminals. Note the wire locations or take a picture for reference later.
6. Remove the Old Start Button:
The start button may be held in place with screws or clips. If it's secured with screws, use your screwdriver to remove them. If it uses clips, carefully release the clips by pressing them inward or prying them open with a flathead screwdriver.
7. Install the New Start Button:
Take your replacement start button and align it with the holes or slots on the control panel. If the button has screw holes, secure it in place using the screws you removed from the old button. If it uses clips, carefully snap it into position.
8. Reconnect the Wiring:
If you replaced the start button, reconnect the wires to the appropriate terminals on the back of the new button. Ensure that each wire is connected securely based on your earlier notes or reference photo.
9. Reassemble the Dryer:
With the new start button in place and the wiring reconnected, you can now reassemble the control panel or any panels you removed earlier. Secure them with the screws you removed in step 4.
10. Final Check:
Perform a final check to ensure that all connections are secure, and there are no loose parts or wires. Once you're confident that everything is in order, plug the dryer back into the electrical outlet or turn on the circuit breaker.
11. Test the New Start Button:
Power on the dryer and test the new start button by pressing it to initiate a drying cycle. Make sure it activates the dryer's motor and control board correctly.

By following these steps carefully and taking safety precautions, you can successfully replace the start button on your Whirlpool dryer model LER7646EQ0. If you encounter any difficulties or are unsure about any steps, consider consulting a professional appliance repair technician for assistance.
