We will discuss troubleshooting steps to help you determine the root of the problem and get your dryer up and running again.

By following these simple steps, you may be able to avoid a costly repair service and solve the issue on your own. Let’s explore the potential reasons for your Whirlpool dryer not starting and how to troubleshoot them effectively.

Power Supply Check

Whirlpool Dryer Troubleshooting Won’t Start – Power Supply Check

If your Whirlpool dryer won’t start, the first step in troubleshooting is to check the power supply. Problems with the power outlet or the power cord could prevent the dryer from starting properly.

Check Power Outlet

Before examining the dryer itself, make sure the power outlet is functioning correctly. Follow these steps to check the power outlet:

  1. Ensure the outlet is providing power by plugging in another appliance or electronic device.
  2. If there’s no power, reset the circuit breaker or replace any blown fuses.
  3. If the outlet still doesn’t work, consult a professional electrician to inspect and repair the outlet.

Inspect Power Cord

Next, examine the power cord of your Whirlpool dryer. A damaged or improperly connected power cord can prevent the dryer from starting. Follow these steps to inspect the power cord:

  • Check for any visible signs of damage, such as frayed or exposed wires.
  • Ensure the power cord is securely plugged into the power outlet and the dryer’s terminal block.
  • If any damage is found, disconnect the power cord and replace it with a new one that matches the dryer’s specifications.

Door Switch Inspection

One of the possible issues that may lead to your Whirlpool dryer not starting is a malfunctioning door switch. The door switch is designed to prevent the dryer from operating when the door is open. If the door switch is faulty, it can cause the dryer to not start. In this section, we’ll discuss how to test the door switch for malfunction.

Testing For Malfunction

To ascertain whether the door switch is the cause of the problem, follow these steps:

  1. Unplug the dryer from the power source for safety.
  2. Locate the door switch, typically situated around the dryer door frame.
  3. Use a multimeter to test for continuity in the switch. You should see a reading of zero or close to zero ohms when the door is closed, and an infinite reading when the door is open. If the readings do not align with this pattern, the door switch may be malfunctioning.
  4. If the door switch fails the continuity test, it may need to be replaced.

Ensuring Proper Functioning

After testing for malfunction, it’s important to ensure that the door switch is functioning correctly. This involves checking for any obstructions that may prevent the switch from engaging when the door is closed. Additionally, make sure the switch’s wiring is secure and undamaged, as loose connections or frayed wires can also cause the switch to fail.

Thermal Fuse Examination

When it comes to troubleshooting a non-starting Whirlpool dryer, examining the thermal fuse is a critical step. The thermal fuse is a safety device designed to prevent the dryer from overheating. If the thermal fuse is faulty, the dryer won’t start. By understanding how to identify and replace a faulty thermal fuse, you can effectively address this common issue and get your dryer back up and running.

Identifying Faulty Fuse

If your Whirlpool dryer won’t start, one of the first things to examine is the thermal fuse. To check if the thermal fuse is faulty, follow these steps:

  1. Unplug the dryer from the power source.
  2. Locate the thermal fuse, usually found in the exhaust duct inside the back cover panel.
  3. Use a multimeter to test the continuity of the thermal fuse. If there is no continuity, the thermal fuse is likely faulty.

Replacing Thermal Fuse

If the thermal fuse is found to be faulty, it will need to be replaced. To replace the thermal fuse, follow these steps:

  1. Obtain a replacement thermal fuse compatible with your Whirlpool dryer model.
  2. Unplug the dryer before starting any repairs.
  3. Remove the back cover panel to access the thermal fuse.
  4. Disconnect the wires from the faulty thermal fuse and remove it from its housing.
  5. Install the new thermal fuse and reattach the wires, ensuring a secure connection.
  6. Reattach the back cover panel and plug the dryer back in to test if it starts properly.

Start Switch Assessment

When dealing with a malfunctioning Whirlpool dryer that won’t start, the Start Switch Assessment is a crucial step in troubleshooting. The start switch is what initiates the drying cycle, and a faulty switch can result in the appliance remaining unresponsive. In this section, we will focus on verifying the functionality of the start switch to help identify and potentially resolve the issue.

Verifying Start Switch Functionality

To ensure the start switch is functioning correctly, follow these steps:

  1. Unplug the dryer from the power source for safety purposes.
  2. Locate the start switch, usually found on the control panel.
  3. Inspect the start switch for any visible signs of damage or wear.
  4. Using a multimeter, test the continuity of the start switch to determine if it is effectively completing the electrical circuit when activated.

Ensuring Start Switch Wiring Integrity

If the start switch passes the continuity test and appears undamaged, the next step is to evaluate the wiring connected to the start switch.

  1. Check for any loose or disconnected wires leading to the start switch.
  2. Inspect the wiring harness for signs of fraying or damage that may be affecting the electrical connection to the switch.
  3. Ensure the wiring is securely attached to the start switch and there are no signs of corrosion or rust affecting the connections.
