8 Common Causes Of a Noisy Whirlpool Dryer Machine

Check the Timer Settings

Dealing with a Whirlpool dryer that won’t stop running can be frustrating, but before assuming the worst, start by checking the timer settings. Here’s how to troubleshoot:

  • Inspect the timer knob for proper alignment with the control panel settings.
  • Gently adjust the knob to ensure it clicks into place at each setting.
  • If the issue persists, disconnect power and examine the timer assembly with a multimeter.
  • Check for faults in the control board that may affect the timing mechanism.
  • Ensure proper ventilation to prevent overheating and sensor malfunctions.
  • Regularly clean venting systems to maintain optimal performance and prevent problems.

Thoroughly examining and addressing timer-related issues can efficiently troubleshoot a Whirlpool dryer that won’t stop running. If problems persist, further troubleshooting steps may be necessary.

Examine the Door Switch

When dealing with a Whirlpool dryer that won’t stop running, start by checking the door switch. This switch ensures the dryer operates only when the door is closed securely. If faulty, it can cause the dryer to keep running continuously.

  • Unplug the dryer and locate the door switch assembly near the door latch.
  • Remove any screws and wires, inspecting the switch for damage or wear.
  • Look for broken wires or loose connections, as these may indicate a faulty connection.
  • Test the door switch with a multimeter set to measure continuity.
  • Expect a closed circuit when the door is shut and an open circuit when it’s opened.

Consult your Whirlpool dryer manual for specific instructions as designs and testing procedures may vary. Thoroughly examining and testing the door switch helps identify and resolve related problems effectively.

Verify the Moisture Sensor

The moisture sensor in a Whirlpool dryer is vital for detecting clothes’ moisture level and signaling when they’re dry. If it malfunctions or gets dirty, the dryer may run continuously.

  • Start by unplugging the dryer for safety.
  • Locate the sensor near the lint screen or inside the drum and clean it with a soft cloth and mild detergent.
  • Dry thoroughly before reconnecting power.

Testing tools designed for dryer sensors can diagnose faults accurately. Seek professional help if troubleshooting doesn’t work.

Inspect the Cycling Thermostat

When a Whirlpool dryer won’t stop running, a malfunctioning cycling thermostat could be the issue. Here’s how to inspect it:

  • Unplug the dryer for safety.
  • Locate the cycling thermostat near the heating element or blower wheel housing.
  • Use a multimeter to test continuity:
  • Disconnect wires from the thermostat terminals.
  • Measure resistance with the multimeter probes.
  • A reading close to zero ohms indicates proper function.
  • An infinite reading signals a faulty thermostat, needing replacement.

Evaluate the Control Board

The control board in your Whirlpool dryer regulates its functions, including cycle duration. If the dryer won’t stop running, the control board may be the reason.

  • Ensure you have tools like a multimeter and screwdriver.
  • Disconnect the dryer from power for safety.
  • Remove screws holding the control panel, and disconnect wires.

Inspect the control board for damage or loose connections. If found:

  • Replace the control board if damaged.
  • Use a multimeter for further testing following manufacturer guidelines.

If the dryer still won’t stop:

  • Visually inspect circuitry for damage or loose connections.
  • Use a multimeter for advanced testing according to manufacturer instructions.
  • Always prioritize safety by disconnecting power before working on electrical components.

Assess the Start Switch

Assessing the start switch in a Whirlpool dryer is crucial for resolving issues like continuous operation. Here’s how:

Visual Inspection

  • Check for visible damage or loose connections around the start switch.
  • Tighten or replace any loose wires or frayed cables.

Testing Continuity

  • Use a multimeter to test the continuity of the start switch.
  • A properly functioning switch should show zero resistance when pressed and infinite resistance when not pressed.


  • Remove any debris accumulation around the start switch using a soft cloth or compressed air.

Remember, if unsure, seek professional assistance for Whirlpool dryer repair to ensure proper handling and resolution of issues with the start switch. Regular maintenance and troubleshooting help keep the dryer functioning smoothly.

Examine the Venting System

Proper ventilation is crucial for your Whirlpool dryer’s efficiency and safety. A clogged venting system can cause various issues, including a dryer that won’t stop running.

  • Visually inspect the external vent hood for obstructions.
  • Check for damage or disconnection in the vent pipe.
  • Examine the entire length of the vent pipe for blockages.


Troubleshooting and fixing a Whirlpool dryer that won’t stop running can be a daunting task, but armed with the right knowledge and tools, it is possible to overcome this issue. By following these seven pro tips, you can narrow down the potential causes and find an effective solution. Firstly, always start by checking the timer settings.

By employing these troubleshooting techniques and maintaining regular maintenance practices like cleaning your dryer vents periodically, you can prevent your Whirlpool dryer from running continuously in most cases. Remember that safety should always be a top priority when working on electrical appliances.

If you are uncertain about performing any repair on your own, consult a professional technician who specializes in Whirlpool dryer troubleshooting. With patience and persistence, you can successfully fix your Whirlpool dryer so that it operates smoothly once again – saving yourself time and money while ensuring your laundry routine remains uninterrupted.
