Common Causes
Dryers often stop heating due to several common problems. These issues affect the dryer’s ability to generate or maintain heat. Identifying these causes helps fix the problem quickly and safely.
Some causes are simple to check, like lint buildup. Others need technical skills, such as testing electrical parts. Understanding each cause aids in proper troubleshooting and repair.
Clogged Lint Screen
The lint screen traps fibers from clothes. If clogged, air cannot flow properly. This reduces heat and drying efficiency. Clean the screen after every load to avoid blockages.
Blocked Dryer Vent
The vent carries hot air outside. A blocked vent traps heat inside the dryer. This causes overheating and may trigger safety devices. Clear the vent hose and outlet regularly to ensure airflow.
Blown Thermal Fuse
The thermal fuse stops the dryer if it overheats. A blown fuse cuts power to the heating element. It usually blows due to vent blockages. Replacing the fuse often fixes the heating issue.
Faulty Heating Element
The heating element warms the air inside the dryer. If it breaks or burns out, no heat will be produced. Testing the element with a multimeter can confirm if it needs replacement.
Malfunctioning Thermostat
The thermostat controls dryer temperature. A faulty thermostat may stop the heater from turning on. It can also cause the dryer to overheat. Checking and replacing a bad thermostat restores proper heating.
Gas Valve And Igniter Issues
Gas dryers use a valve and igniter to create heat. If the valve fails or the igniter breaks, the dryer won’t heat. These parts need inspection and possible replacement by a professional.
Timer And Control Board Problems
The timer and control board manage the dryer’s functions. Faulty controls can stop the heating cycle. Diagnosing these electrical parts requires experience. Repair or replacement may be necessary for proper heating.

Quick Fixes
Quick fixes often solve the problem of a dryer not heating. These simple steps save time and money. Try these easy methods first before calling a repair service.
Clean The Lint Screen
Lint buildup blocks airflow and stops the dryer from heating. Remove the lint screen and clean off all lint. Use water and a soft brush for a deep clean. Clean the screen after every load to keep air flowing freely.
Clear The Dryer Vent
A clogged dryer vent causes poor heating and longer drying times. Disconnect the vent hose from the dryer and remove lint inside. Also, check the vent opening outside your home. Clear any blockages to restore proper airflow.
Reset The Circuit Breaker
The dryer may stop heating due to a tripped circuit breaker. Locate your home’s electrical panel and find the dryer breaker. Switch it off and then back on to reset. This can restore power to the heating element.
Testing Components
Testing components in a dryer helps find why it won’t heat. Each part plays a role in creating heat. Checking these parts saves time and money. You can do simple tests at home with basic tools. Follow these steps to identify the faulty component.
Check Thermal Fuse
The thermal fuse prevents the dryer from overheating. It cuts power to the heating element if the dryer gets too hot. Use a multimeter to test for continuity. No continuity means the fuse is blown. Replace the thermal fuse if it is faulty. Always unplug the dryer before testing.
Test Heating Element
The heating element creates the heat inside the dryer. A broken or burnt element stops heat production. Remove the heating element and check it with a multimeter. Look for any breaks or damage on the coil. Replace the element if it shows no continuity or damage.
Inspect Thermostat
The thermostat controls the temperature inside the dryer. A bad thermostat can stop the dryer from heating. Test the thermostat with a multimeter for continuity. Check the operating and high-limit thermostats separately. Replace any thermostat that fails the test.
Examine Gas Valve And Igniter
Gas dryers use a gas valve and igniter to create heat. The igniter lights the gas to produce heat. Test the igniter for continuity with a multimeter. Inspect the gas valve coils for damage or wear. Replace the igniter or coils if they do not work properly.
Replacing Parts
Replacing parts is often necessary when a dryer won’t heat. Some components wear out over time or fail due to overheating. Knowing which parts to replace can restore your dryer’s function quickly. Focus on key parts like the thermal fuse, heating element, thermostat, and gas valve or igniter. Each part has a specific role in generating heat. Replacing these parts carefully can solve most heating problems.
Swap Thermal Fuse
The thermal fuse stops the dryer from overheating. If it blows, the dryer will run but not heat. Test the fuse with a multimeter for continuity. No continuity means it is blown and needs replacement. Remove the old fuse and install a new one in the same spot. This is a common and simple fix for dryers that won’t heat.
Replace Heating Element
The heating element produces the heat inside electric dryers. It can burn out or break, causing no heat. Disconnect the dryer from power before checking the element. Use a multimeter to test for continuity. Replace the heating element if it shows no continuity or visible damage. Installing a new element restores proper heating in most cases.
Change Faulty Thermostat
The thermostat controls the dryer’s temperature. A bad thermostat can stop heating or cause overheating. Test the thermostat for continuity using a multimeter. Replace the thermostat if it fails the test. This part ensures the dryer heats evenly and safely. Proper thermostat function protects your clothes and the appliance.
Fix Gas Valve Or Igniter
Gas dryers rely on the gas valve and igniter to create heat. A faulty igniter will not light the gas, so no heat is produced. Check the igniter for cracks or damage. Replace it if broken. The gas valve coils can also fail, preventing gas flow. Test and replace faulty coils to restore heat. These repairs may require careful handling of gas connections.
When To Get Help
Knowing when to get help for a dryer that won’t heat is important. Some problems are simple to fix. Others need expert attention. Recognizing the signs can save time and prevent damage.
Complex Repairs
Some dryer issues require special tools and skills. Problems like faulty thermostats, wiring faults, or control board failures are complex. Attempting these repairs without experience can cause more harm. Professionals have the training to fix these safely and correctly.
Safety Concerns
Dryers use electricity and heat. This combination can be dangerous. Handling electrical parts without proper knowledge risks shock or fire. A clogged vent or damaged heating element can also cause hazards. Safety should always come first when dealing with dryer repairs.
Finding A Professional
Choose a certified appliance repair technician. Check reviews and ask for recommendations. Make sure they have experience with your dryer brand. A good professional will provide a clear estimate and explain the repair process. This ensures your dryer is fixed right the first time.
