5. Problem with Gas Valve Solenoid (Gas Dryers)

For gas dryers, a malfunctioning gas valve solenoid can be a reason for no heat.

The solenoid is responsible for opening and closing the gas valve to enable heat production. If the solenoid is bad, the gas flow to the dryer will be disrupted, and causing the lack of heat you are experiencing.

Refer to your dryer’s manual to locate the gas valve solenoid, but it’s recommended to seek professional assistance for the dryer repair or replacement.

6. Faulty Igniter (Gas Dryers)

Gas dryers rely on an igniter to light the gas and generate heat. If the igniter is not working correctly, the gas will not ignite, causing the dryer to remain cold.

While it may be possible to test the igniter with a multimeter, it’s advisable to contact your gas company for assistance and prioritize safety due to the explosive nature of the gas.

7. Main Control Board Issues

The main control board acts as the central hub of the dryer, regulating its various functions. If the control board malfunctions, it may fail to transmit signals properly, leading to a lack of heat.

Repairing or replacing the main control board can be expensive and complex. Consult a professional technician to assess the issue and determine the best action.

8. Incorrect Dryer Settings

Sometimes, a dryer heating issue can be attributed to incorrect settings or a wrongly set timer.

Ensure you have selected the appropriate heat setting and the timer is functioning correctly to enable the dryer to heat up properly.

How to Fix a Dryer That’s Not Heating

If your dryer is not heating, here are some steps you can take to troubleshoot and potentially fix the issue:

1. Check for a Clogged Dryer Vent

clogged vent is a frequent culprit behind a dryer not heating effectively.

Start by inspecting the lint trap and ensuring it is clean after every load. A buildup of lint can obstruct the airflow, preventing proper heating.

Additionally, cleaning the dryer vent at least once a year is essential. If accessible, remove the vent (exhaust duct) cover and dryer hose and clear any debris or obstructions. Regular vent maintenance can help prevent fire hazards and improve the dryer’s performance.

2. Examine the Thermal Fuse

The thermal fuse is responsible for detecting the internal temperature of the dryer.

A faulty thermal fuse can hinder the dryer’s ability to determine the appropriate heat level, leading to inadequate heating.

Consult your dryer’s manual to locate the thermal fuse, and consider using a multimeter to test its functionality. If the thermal fuse is defective, seeking professional assistance for replacement is recommended, as attempting to replace it independently may void the warranty.

3. Assess the Heating Element

malfunctioning heating element can also contribute to a dryer not generating sufficient heat.

Refer to the manual if you can’t find your dryer’s heating element. Once you have found it, use a multimeter to test its current flow. If the current flow is inadequate, it indicates a need for replacement.

Due to the complexity involved, it is advisable to rely on professional help to replace the heating element. Before you go ahead with replacing your dryer’s heating element, compare the cost of a new heating element to the cost of a new dryer to determine the most cost-effective solution.

4. Verify the Timer Operation

Modern dryers utilize timers to regulate the heating cycles accurately. If the timer is not advancing correctly, it can disrupt the dryer’s cycling and result in inadequate heating of wet clothes.

Troubleshooting the timer can be challenging, as the issue could be related to internal wiring or specific components.

To address timer-related problems, seeking professional assistance is advisable for accurate diagnosis and resolution.

5. Inspect the Gas Valve Solenoid (for Gas Dryers)

Gas dryers rely on a gas valve solenoid to control gas flow for heating purposes. If a gas dryer fails to heat up adequately, the gas valve solenoid or gas valve coil may be at fault.

The first step is locating the solenoid, as described in the manual. However, repairing or replacing the gas valve solenoid is a task that is best left to professionals due to the potential hazards of gas appliances.

6. Examine the Igniter (for Gas Dryers)

In gas dryers, the igniter plays a crucial role in igniting the gas that generates heat. If the igniter malfunctions, the gas will not ignite, resulting in a lack of heat.

Testing the igniter using a multimeter can provide insights into its functionality, but it is recommended to involve a professional due to the safety concerns associated with gas appliances.

7. Evaluate the Main Control Board

The main control board is responsible for coordinating various functions within the dryer. If the main control board malfunctions, it can impact the heating capability of the dryer.

Unfortunately, repairing or replacing the main control board can be expensive. In such cases, it is advisable to consult a professional to assess whether the control board can be fixed or if replacing the entire dryer is more viable.


How much does it cost to replace a thermal fuse in a dryer?

The cost of replacing a thermal fuse in a dryer can vary depending on several factors, including the brand and dryer model, the location, and the labor charges.
