Whirlpool Dryer Error Code SYMPTOM-NOT-HEATING — How to Fix (Dryer not heating)

Field note: SYMPTOM-NOT-HEATING is too much heat / not enough airflow until the vent is proven clear. On Whirlpool dryers, clean the lint path through the wall cap so you can feel strong exhaust outdoors. Crushed foil hose and a bird nest beat a new heating element. Replace a thermal fuse only after airflow is fixed or it will open again.

What this code is not

• Not a ‘new heating element first’ code.
• Not a Wi-Fi or child-lock issue.
• A new fuse with a still-clogged vent will open again, often on the next load.

The SYMPTOM-NOT-HEATING error code on your Whirlpool dryer indicates that the dryer is not producing heat. This can be a frustrating issue, especially if you’re in the middle of a laundry cycle. Before we dive into the troubleshooting process, let’s take a moment to understand what this error code means and what might be causing it.

What’s Actually Failing Inside

Based on our experience and customer feedback, here are the most common causes of the SYMPTOM-NOT-HEATING error code on Whirlpool dryers:

1. Faulty Heating Element

• Description: The heating element is responsible for producing heat in your dryer. If it’s faulty, the dryer won’t heat up.
• How to verify: Use a multimeter to test the heating element’s resistance. If it’s within the recommended range (usually around 10-20 ohms), it’s likely good. If not, it’s faulty.
• Fix difficulty: 6/10
• Cost: $50-$100 (part number: WED51A0AW0)

2. Blown Thermal Fuse

• Description: The thermal fuse is a safety device designed to prevent overheating. If it blows, the dryer won’t heat up.
• How to verify: Use a multimeter to test the thermal fuse’s continuity. If it’s open (no continuity), it’s blown.
• Fix difficulty: 4/10
• Cost: $10-$30 (part number: 3392519)

3. Electrical System Issues

• Description: A problem with the electrical system, such as a faulty thermostat or a malfunctioning timer, can trigger the SYMPTOM-NOT-HEATING error code.
• How to verify: Use a multimeter to test the electrical system’s components. Consult a professional if you’re not comfortable with electrical testing.
• Fix difficulty: 8/10
• Cost: $100-$300

4. Clogged Venting System

• Description: A clogged venting system can cause the dryer to overheat and trigger the SYMPTOM-NOT-HEATING error code.
• How to verify: Inspect the venting system for blockages and clean it if necessary.
• Fix difficulty: 3/10
• Cost: $0 ( DIY)

5. Faulty Thermostat

• Description: The thermostat regulates the dryer’s temperature. If it’s faulty, the dryer won’t heat up.
• How to verify: Use a multimeter to test the thermostat’s resistance. If it’s within the recommended range (usually around 10-20 ohms), it’s likely good. If not, it’s faulty.
• Fix difficulty: 6/10
• Cost: $50-$100 (part number: WEM22)

Hands-On Repair Instructions

The most common cause of the SYMPTOM-NOT-HEATING error code on Whirlpool dryers is a faulty heating element. Here’s a step-by-step guide to replace it:

Tools needed: Phillips screwdriver, Torx T20 screwdriver, multimeter

Time estimate: 1-2 hours

Safety warnings:

• Unplug the dryer from the power outlet before starting the repair.
• Wear protective gloves and safety glasses.

Step-by-Step Instructions:

1. Unplug the dryer and remove the back panel using a Phillips screwdriver.
2. Locate the heating element, usually found at the bottom of the dryer.
3. Use a Torx T20 screwdriver to remove the screws holding the heating element in place.
4. Gently pull the heating element out of the dryer.
5. Use a multimeter to test the new heating element’s resistance.
6. Install the new heating element and reattach the screws.
7. Reassemble the dryer and plug it back in.

What “fixed” looks like: The dryer should now heat up properly, and the SYMPTOM-NOT-HEATING error code should be resolved.

How This Varies by Model

While the SYMPTOM-NOT-HEATING error code is common across many Whirlpool dryer models, some models may have specific differences:

• Whirlpool WED51A0AW0: This model uses a different heating element (part number: WED51A0AW0).
• Whirlpool WED82CS0AW: This model has a more complex electrical system and may require additional testing.

Budget Planning: Repair Costs

Here’s a breakdown of the estimated costs:

When to call a professional:

• If you’re not comfortable with DIY repairs or electrical testing.
• If the issue persists after attempting DIY repairs.

Maintenance Tips to Avoid Recurrence

To prevent the SYMPTOM-NOT-HEATING error code from occurring in the future:

• Regularly clean the lint filter and venting system.
• Check the electrical system’s components for signs of wear.
• Ensure proper installation and maintenance of the dryer.

Time to Call the Pros?

If you experience any of the following symptoms, it’s best to call a professional:

• The dryer is not heating up at all.
• The error code persists after attempting DIY repairs.
• You notice unusual noises, smells, or vibrations.

What to expect:

• A professional technician will diagnose the issue and provide a detailed estimate.
• The repair may take several hours, depending on the complexity of the issue.
