Short answer: A Whirlpool dryer not stopping typically indicates a faulty timer, moisture sensor, or door switch. Diagnosing and replacing the malfunctioning component should resolve the issue.
Whirlpool dryers, renowned for their reliability and efficiency, occasionally face issues like any other household appliance. One such concern that users occasionally report is the dryer not stopping when it’s supposed to. This malfunction can be a symptom of underlying issues, be they mechanical or electronic, and understanding its root causes can be vital not only for the appliance’s optimal performance but also for the safety of the household. In this discussion, I will highlight the potential reasons behind a Whirlpool dryer’s continuous operation and the steps to address them.
Why Whirlpool Gas Dryer Is Not Stopping?
The Whirlpool gas dryer might not be stopping for several reasons:
- Restricted Airflow: One of the main reasons the dryer may not shut off is due to restricted airflow. This can be caused by a kinked or clogged exhaust, or a dirty lint screen, leading to heat build-up and improper cycling of the heat.
- Faulty Timer: The timer, which controls the dryer’s functions, might be malfunctioning. If its contacts are fused together or the motor has failed, the dryer may not shut off at the end of the cycle.
- Defective Start Switch: If the dryer won’t stop at the end of the cycle and the timer keeps advancing, it might be due to a failed start switch.
- Malfunctioning Moisture Sensor: For dryers with an auto dry feature, the moisture sensor, which gauges the wetness of the clothes and adjusts the drying time, might malfunction, causing the dryer to continue running.
- Dryness Control Board Issues: This board sends power to the timer motor in auto-dry settings. If the timer and moisture sensor are working correctly, but the dryer still won’t shut off in auto-dry mode, the board could be at fault.
- Cycling Thermostat Problems: The cycling thermostat regulates the internal temperature of the dryer. If it’s faulty, the timer won’t advance to shut off the dryer.
- Gas Valve Solenoids: These solenoids open the gas valve and allow gas flow. If they’re malfunctioning, the dryer might not get hot enough, affecting its stopping mechanism.
Why Whirlpool Electric Dryer Is Not Stopping?
The reasons for a Whirlpool electric dryer not stopping are:
- Restricted Airflow: This can be due to the exhaust being kinked, clogged, or having a dirty lint screen. The restricted airflow could cause the heat to build up near the heat source, leading to improper cycling of the heat, and as a result, the timer may not advance to the end of the cycle.
- Faulty Timer: The timer controls the functions of the dryer. If its contacts are fused together or the motor has failed, the dryer may not shut off at the end of the cycle.
- Defective Start Switch: If the dryer won’t stop and the timer keeps advancing, the start switch might be the issue. If the dryer starts automatically upon closing the door after a cycle interruption, the switch is likely faulty.
- Malfunctioning Moisture Sensor: For dryers with an auto dry feature, a malfunctioning moisture sensor can be the culprit. The sensor measures the wetness of the clothes and adjusts the drying time. If it thinks the clothes are still wet, the dryer might not shut off.
- Dryness Control Board Issues: This board sends power to the timer motor in auto-dry settings. If the timer and moisture sensor are functioning, but the dryer won’t shut off in auto-dry mode, the board might be at fault.
- Cycling Thermostat Problems: The cycling thermostat regulates the temperature inside the dryer. If it’s faulty, the timer won’t advance to shut off the dryer.
- Damaged Heating Element: The heating element heats the air before it enters the dryer drum. If it’s damaged or not producing enough heat to trip the cycling thermostat, the timer may not advance to the end of the cycle.
Fixing Whirlpool Electric Dryer Won’t Stop Running
Step 1: Identify the Problem: The primary issue is the dryer doesn’t stop when the door is opened.
Step 2: Suspected Faulty Part: The door switch is suspected to be faulty. This switch informs the dryer to stop running when the door is opened.
Step 3: Accessing the Door Switch:
- Remove the lint filter.
- Expose and unscrew the two Phillips head screws.
- Lift the dryer’s lid using a putty knife or a similar tool. Slide the knife into the side until it stops, then push it forward and lift the top. Do this on both sides to release the locking tabs, allowing the lid to be opened.
Step 4: Removing the Old Door Switch:
- Locate the door switch at the front.
- Disconnect its wiring harness.
- Open the door to see two Phillips head screws that hold the switch in place. Remove these screws.
- Lift out the door switch from the top.
Step 5: Testing the Door Switch: Use a multimeter to test for continuity (an unbroken electrical circuit). The old door switch should give a continuous tone, indicating it’s faulty. A new switch should give a tone only when its button is pressed, indicating it’s functional.
Step 6: Installing the New Door Switch:
- Slide the switch’s black tab through the slot in the front.
- Connect the wiring harness to the switch. The tapered end of the harness ensures correct installation.
- Secure the switch with the two Phillips screws.
Step 7: Finishing Up:
- Close the dryer lid and press down to lock it in place.
- Replace the two screws near the lint filter and then reinstall the lint filter.
- Plug in the unit.
Step 8: Test the Dryer: Start the dryer, and when you open the door, it should stop running, confirming the issue has been resolved.
Fixing Whirlpool Gas Dryer Won’t Stop Running
To fix a Whirlpool gas dryer that isn’t turning off:
- Timer/Motor Control: Start with the most common issue: the timer or motor control. If the timer or the control board that regulates the motor is malfunctioning, the dryer might not stop. Check for any burned-out sections or any visibly damaged components. If it seems defective, consider replacing it.
- Door Switch: The door switch detects if the dryer door is closed. If it fails, the dryer might not stop when the door is opened. Test the door switch for continuity using a multimeter. If it’s faulty, it should be replaced.
- Cycling Thermostat: The cycling thermostat monitors the temperature inside the dryer drum. If it’s malfunctioning, the dryer may not know when to stop. Check the thermostat for continuity and replace it if necessary.
- Moisture Sensor (for models with this feature): Some modern dryers come with a moisture sensor that detects how wet the clothes are and adjusts the drying time accordingly. If this sensor is malfunctioning, it could keep the dryer running indefinitely. Clean the sensor bars with rubbing alcohol to remove any residue. If the problem persists, consider replacing the sensor.
- Shorted Heating Element: Though it’s more common for heating elements to burn out completely, they can sometimes short out, causing the dryer to continue running. Check the heating element for any signs of damage or shorting.
- Drive Motor: In rare cases, if the motor’s internal switch fails, it can cause the dryer to continue running even after it’s supposed to stop. If everything else checks out, inspect the motor and consider replacing it if you suspect it’s the culprit.
- Check the User Control and Display Board: Sometimes, the machine control board could be at fault. If it’s not communicating correctly with the timer or other components, the dryer might not stop as it should. This is a less common reason but worth checking if all other options have been ruled out.
