5 Common Reasons Whirlpool Duet Dryers Not Heating Up & Their Fixes

Whirlpool Duet dryers, both electric and gas models, may face issues with not heating up. This common problem affects many owners of these appliances.

A Whirlpool Duet dryer that is not heating up could be suffering from several causes. Malfunctioning heating elements, faulty thermostats, or problems with the fuses could be contributing to this issue. These elements are present in both electric and gas variants of the dryer.

The question of why a Whirlpool Duet dryer, whether gas or electric, would not heat up often leads to an inspection of the power supply. A proper connection is crucial for the heating mechanism to function, and any inconsistencies could lead to the problem.

If the question is how to fix a Whirlpool Duet dryer not heating, the answer often lies in diagnosing the specific issue. It might be as simple as replacing a blown fuse or as complicated as fixing a broken heating element. In some instances, professional service may be required to diagnose and correct the issue.

Understanding why a dryer would not heat up involves examining the various components that contribute to heating. For a Whirlpool Duet dryer, proper maintenance and timely inspection of heating elements and other related parts can prevent this problem and ensure a fully functional appliance.

Reasons for Whirlpool duet dryer not heating up and their solutions

The Whirlpool Duet dryer’s lack of heating may result from various factors, and understanding each one helps in effective troubleshooting. Here, we will examine the common reasons and provide guidance on how to fix them.

1. Faulty Heating Element

The heating element in an electric Whirlpool Duet dryer is responsible for generating heat. If it becomes defective, the dryer won’t heat up.

• Diagnosis: You can use a multimeter to test the heating element for continuity.
• Fix: Replace the heating element if it lacks continuity.

2. Broken Thermal Fuse

The thermal fuse is a safety device that prevents the dryer from overheating. It can blow, causing the dryer not to heat.

• Diagnosis: Again, a multimeter will be useful to test the thermal fuse for continuity.
• Fix: Replace the thermal fuse if found defective.

3. Malfunctioning Gas Valve Solenoid

For a Whirlpool Duet gas dryer, the gas valve solenoid controls the gas flow. A failure in this part will prevent the dryer from heating.

• Diagnosis: You can inspect the igniter and test the solenoids with a multimeter.
• Fix: Replacing the gas valve solenoids should resolve the problem.

4. Thermostat Issues

A thermostat controls the temperature inside the dryer, and a faulty thermostat will interfere with heating.

• Diagnosis: Testing the thermostat for continuity with a multimeter will detect if it’s the issue.
• Fix: Replace the thermostat if needed.

5. Cycling Thermostat Failure

The cycling thermostat regulates the temperature by cycling the heating element on and off. A failure here can lead to no heat.

• Diagnosis: Test the cycling thermostat for continuity, similar to other components.
• Fix: Replacing the cycling thermostat should correct the problem.

Sensing But Not Starting: Whirlpool Duet Dryer Issue

A common problem with Whirlpool Duet dryers is the machine sensing but not starting, indicating an underlying problem with the dryer’s functions. Here are potential causes and solutions:

1. Door Switch Failure: If the door switch is not functioning properly, the dryer might sense the load but will not start.

• Diagnosis: Test the door switch for continuity using a multimeter.
• Fix: Replace the switch if necessary.

2. Start Switch Issue: Sometimes, the start switch itself might be the problem.

• Diagnosis: You can again utilize a multimeter to test if the switch has continuity.
• Fix: Replace the start switch if it is the culprit.

3. Motor Malfunction: The motor might also be at fault, preventing the machine from starting.

• Diagnosis: Listen for humming noises, which could indicate a motor problem.
• Fix: Consult a technician for a motor replacement.

By diagnosing and fixing these areas, you can address the problem of your Whirlpool Duet dryer sensing but not starting.

Whirlpool Duet Dryer: Troubleshooting Codes

Whirlpool Duet dryers come with a diagnostic system displaying codes that represent specific problems. Here’s how to interpret some of these codes:

1. F-01: This code signifies a main electronic control failure.

• Fix: Reset the control board. If the error persists, it may need to be replaced.

2. F-22: This code is linked to a failed outlet thermistor.

• Fix: Check the thermistor and replace it if defective.

3. F-28: This code means that the moisture sensor has malfunctioned.

• Fix: Inspect the wiring, and replace the sensor if needed.
