How To Fix a Whirlpool Dryer That Won’t Stop Running? 7 Pro Tips

1. Check Power Source

When dealing with a Whirlpool dryer that won’t start, start by checking the power source to rule out basic issues. Inspect the power cord for damage and ensure it’s plugged into a working outlet. Test the outlet with another appliance to confirm power supply.

  • Check power cord and outlet connection for damage or loose connections.
  • Test outlet with another appliance to confirm power supply.
  • Inspect circuit breaker or fuse box for tripped breakers or blown fuses.

Reset tripped breakers and replace blown fuses with matching amperage. Test another appliance on the dryer’s circuit to rule out dedicated circuit issues. By ensuring proper power supply, you can eliminate common causes of a non-starting Whirlpool dryer and focus on resolving other potential problems.

2. Examine Door Switch

When dealing with a Whirlpool dryer that won’t start, check the door switch first as it’s a common culprit. The door switch detects if the door is open or closed and can prevent the dryer from starting if it’s faulty.

  • Begin by unplugging the dryer for safety.
  • Access the door switch by removing necessary parts like screws or clips.
  • Inspect the switch for visible damage, loose connections, or burned contacts.
  • Check for continuity by pressing the switch or closing an imaginary door.
  • Use a multimeter to perform a continuity test.
  • A faulty switch may need replacement to resolve the issue.

Replacing a faulty door switch can effectively fix a non-starting Whirlpool dryer. Consult an authorized technician or a comprehensive appliance troubleshooting guide for detailed replacement instructions.

3. Thermal Fuse Inspection

When troubleshooting a Whirlpool dryer that won’t turn on, checking the thermal fuse is crucial. It prevents overheating and potential hazards. Here’s what to do:

Inspect Thermal Fuse

  • Access the thermal fuse location, usually on the back panel or inside the dryer cabinet near the heating element.
  • Use caution and refer to the dryer repair guide if necessary.

Test for Continuity

  • Disconnect both wires from the thermal fuse.
  • Use a multimeter to check continuity by placing probes on each terminal.

Replacement and Maintenance

  • If there’s no continuity, the thermal fuse is blown and needs replacement.
  • Factors like high heat or lint accumulation can cause this issue.

After replacing the fuse, address any underlying problems by cleaning lint build-up and ensuring proper airflow.

4. Control Board Assessment

Encountering a non-starting Whirlpool dryer often leads to troubleshooting its control board, a crucial component dictating the machine’s functions. Power issues are common, and a faulty control board could be to blame. To investigate:

  • Ensure no power to the dryer and check for electrical disruptions.
  • Assess the control board’s functionality by unplugging the dryer and inspecting it for damage.
  • Use a multimeter to test components for proper functionality, focusing on power cord terminals and related connectors.

If abnormalities are found or suspected, replacement or repair may be necessary. Consult the manufacturer’s manual or seek professional assistance for accurate diagnosis and resolution.

5. Motor and Belt Examination

When dealing with a non-starting Whirlpool dryer, checking the motor and belt is essential. The motor drives the drum’s rotation, while the belt ensures power transmission. Follow these steps:

  • Disconnect the dryer and locate the motor assembly at the rear.
  • Inspect for visible damage or burning, then test for continuity with a multimeter.
  • Access the interior safely and examine the belt for wear, cracks, or misalignment.

Thoroughly examining these components helps troubleshoot startup issues effectively. Refer to the dryer repair guide or seek professional assistance if faults are found.

6. Timer Check

When dealing with a Whirlpool dryer that won’t start, one crucial part to inspect is the timer. Here’s a simplified guide:

  • Unplug the dryer for safety.
  • Locate the timer on the control panel and visually inspect it for damage.
  • Conduct a continuity test using a multimeter to check electrical flow.
  • Touch one probe to the “C” terminal and the other to each terminal while rotating the dial.
  • Look for continuity or open circuits; faulty readings indicate a defective timer.
  • Replace the timer if necessary, readily available at repair stores and online retailers.

Checking the timer is vital for resolving startup issues in Whirlpool dryers. Follow these steps to troubleshoot and fix the problem effectively.

7. Start Switch Evaluation

When troubleshooting a Whirlpool dryer that won’t start, focus on the start switch as a potential culprit. Follow these steps to diagnose and address the issue efficiently:

Inspect Start Switch

  • Unplug the dryer and locate the start switch on the control panel.
  • Look for visible damage or wear, like loose wires or burnt connections.

Perform Continuity Check

  • Disconnect wires from the switch terminals and use a multimeter to check for continuity.
  • Activate the switch and ensure it shows continuity when pressed and none when released.

Replace Defective Switch

  • If the switch doesn’t exhibit proper continuity or shows damage, replace it with a compatible part.
  • Refer to Whirlpool’s repair guide for model-specific instructions or seek professional help if needed.

Always prioritize safety and consult reliable resources when conducting dryer repairs. Equip yourself with essential tools like a multimeter, screwdriver set, and wire strippers to effectively address start switch issues and restore dryer functionality.

8. Thermal Cut-Off Inspection

The thermal cut-off is vital for your Whirlpool dryer’s safety and efficiency. If your dryer won’t turn on, understanding this component is crucial to troubleshoot and fix the issue.

Safety Device Functionality

  • Prevents overheating by cutting off power to the dryer’s heating elements.
  • Works alongside the high-limit thermostat to safeguard against fires or damage from excessive heat.

Inspection and Replacement

  • Locate the thermal cut-off near the dryer’s exhaust duct and check for physical damage.
  • If signs of burning, melting, or discoloration are present, the thermal cut-off needs replacement.

Testing and Replacement Procedure

  • Perform a continuity test using a multimeter to ensure functionality accurately.
  • If no continuity is detected, indicating an open circuit, immediate replacement is necessary for proper dryer function.

Understanding and testing components like the thermal cut-off is essential for diagnosing and fixing dryer issues. However, if unsure or uncomfortable, seek professional assistance for safe and efficient repairs.

9. Consider Internal Wiring

When dealing with a Whirlpool dryer that won’t start, internal wiring problems could be the culprit. It’s essential to conduct a thorough inspection of the wiring to diagnose the issue accurately.

  • Start by unplugging the dryer for safety.
  • Visually inspect wiring for damage like frays or loose connections.
  • Use a multimeter to test electrical connections for continuity.

Check components like the start switch and control board for proper functioning. Any interruptions in continuity may indicate a faulty connection or switch.

  • Inspect the timer and wiring harness for wear or damage.
  • Ensure all connections are secure and free from corrosion.

Fixing internal wiring issues in dryers can be tricky without expertise. Consider consulting a professional Whirlpool dryer repair technician for assistance if needed. Prioritize safety during troubleshooting and seek professional help if unsure.

10. Contact a Professional Whirlpool Dryer Repairman

When DIY troubleshooting fails, it’s time to call a professional Whirlpool dryer repairman. They have the expertise and tools needed to diagnose and fix complex issues efficiently. Control board problems and faulty start switches are common culprits for a dryer not turning on, requiring professional attention for accurate diagnosis and repair.

  • Control board malfunctions or power surges can prevent the dryer from starting.
