A blown thermal fuse can occur if the dryer overheats, cutting off power to the dryer. A defective door switch, which signals that the door is closed, can also prevent the dryer from starting. The start switch may fail, preventing the dryer from turning on. Additionally, the dryer may not be receiving power due to a tripped circuit breaker or a blown fuse in the home's electrical panel. Some dryers have a belt switch that will prevent the dryer from starting if the belt is broken.
The heating element can burn out over time, causing the dryer to stop heating. A blown thermal fuse can also prevent the dryer from heating. The thermostat, which regulates the dryer’s temperature, may fail, preventing proper heating. A clogged vent can restrict airflow, causing the dryer to overheat and not heat efficiently.
Worn-out drum rollers, which support the drum, can cause a thumping noise if they wear out. A worn or damaged belt can cause a squealing or thumping noise. The idler pulley, which keeps tension on the belt, can cause a squeaking or rattling noise if it’s damaged. A loose blower wheel, which circulates air through the dryer, can cause a rattling noise.
A clogged lint filter or vent can restrict airflow, causing the dryer to take longer to dry clothes. Overloading the dryer can prevent clothes from tumbling freely, leading to longer drying times. A partially functioning heating element can reduce the dryer’s efficiency. A defective thermostat can cause the dryer to not heat properly, resulting in longer drying times.
A clogged vent can cause the dryer to overheat and shut off to prevent a fire. A malfunctioning thermostat can cause the dryer to overheat and shut off prematurely. A defective timer can cause the dryer to shut off before the cycle is complete.
The drive belt, which connects the motor to the drum, can break and prevent the drum from spinning. A faulty motor can prevent the drum from turning. Worn-out drum rollers, which support the drum and help it spin smoothly, can cause the drum to stop spinning.
Lint build-up inside the dryer can cause a burning smell and pose a fire hazard. Overheating can cause a burning smell. Damaged or faulty electrical components can also produce a burning smell.
The dryer vent may be clogged, restricting airflow and preventing proper drying. The lint filter may be clogged, reducing airflow and drying efficiency. A faulty heating element can cause the dryer to run without producing enough heat to dry clothes. The dryer drum may not be spinning properly, which can prevent clothes from tumbling and drying evenly.
The dryer may be overheating due to a clogged vent, causing it to shut off as a safety measure. A faulty thermostat can cause the dryer to overheat and shut off prematurely. The motor may be overheating or defective, causing the dryer to stop running after a short period. The moisture sensor may be malfunctioning, causing the dryer to stop prematurely.
Overloading the dryer can prevent clothes from tumbling freely, leading to wrinkling. Leaving clothes in the dryer after the cycle ends can cause them to become wrinkled. A malfunctioning timer or control board can cause the dryer to stop before the cool-down cycle, leading to wrinkling. The dryer drum may not be spinning properly, causing clothes to bunch up and wrinkle.

If your dryer is not starting, it can be frustrating and inconvenient. There are several potential reasons why your dryer might not be operating as expected. Understanding these causes and following the appropriate troubleshooting steps can help you diagnose and possibly fix the issue.
Possible Causes
-
Blown Thermal Fuse:
-
The thermal fuse is a safety device that cuts off power to the dryer if it overheats. A blown thermal fuse is often due to excessive lint build-up, blocked vents, or a malfunctioning thermostat.
-
-
Defective Door Switch:
-
The door switch ensures that the dryer only operates when the door is securely closed. If the switch is faulty, the dryer will think the door is open and will not start.
-
-
Faulty Start Switch:
-
The start switch initiates the drying cycle. If it’s defective, the dryer won't turn on even if you press the start button.
-
-
Power Supply Issues:
-
The dryer may not be receiving power due to a tripped circuit breaker, a blown fuse in the home's electrical panel, or a faulty power cord.
-
-
Broken Belt:
-
The drive belt connects the motor to the drum. A safety switch may prevent the dryer from starting if the belt is broken.
-
-
Faulty Timer:
-
The timer controls the electrical components inside the dryer. If the timer is defective, it may not advance to the start cycle, preventing the dryer from starting.
-
-
Malfunctioning Motor:
-
The motor turns the drum and blower wheel. If the motor is defective, the dryer won't start or may just hum.
-
Troubleshooting Steps
-
Check the Thermal Fuse:
-
Locate the thermal fuse on the dryer, typically near the exhaust vent.
-
Use a multimeter to test for continuity. No continuity means the fuse is blown.
-
Replace the thermal fuse if necessary and ensure dryer vents are clean to prevent future issues.
-
-
Inspect the Door Switch:
-
Open the dryer door and manually press the door switch lever.
-
Listen for a clicking sound and use a multimeter to test for continuity when the switch is pressed.
-
Replace the door switch if there is no continuity or clicking sound.
-
-
Test the Start Switch:
-
Access the start switch, usually located behind the control panel.
-
Use a multimeter to test for continuity. No continuity indicates a defective switch.
-
Replace the start switch if necessary.
-
-
Ensure Proper Power Supply:
-
Verify the dryer is properly plugged into a working outlet.
-
Check your home's electrical panel for tripped circuit breakers or blown fuses and reset or replace them.
-
Inspect the power cord for visible damage and replace it if needed.
-
-
Examine the Belt:
-
Open the dryer cabinet to access the belt.
-
Check if the belt is broken or loose.
-
Replace the belt if it is damaged.
-
-
Check the Timer:
-
Access the timer, typically located in the control panel.
-
Use a multimeter to test for continuity at the timer’s contacts.
-
Replace the timer if it does not show continuity.
-
-
Inspect the Motor:
-
If the dryer hums but does not start, try manually turning the drum to see if it moves freely.
-
Use a multimeter to test the motor windings for continuity.
-
Replace the motor if it is defective.

When to Seek Professional Help
If you have followed these troubleshooting steps and your dryer still won't start, it may be time to consult a professional dryer repair technician. A professional can provide further diagnostics and repairs to ensure your dryer is functioning correctly and safely.
Regular maintenance and professional inspections can prevent many common dryer issues and extend the life of your appliance.
If your dryer is running but not producing heat, it can be frustrating and may result in damp clothes. Several potential causes exist for this issue, and understanding them can help you pinpoint the problem and take appropriate action.
Possible Causes
-
Faulty Heating Element:
-
The heating element generates heat inside the dryer. Over time, it can burn out or become defective, resulting in no heat production.
-
-
Blown Thermal Fuse or Thermostat:
-
A blown thermal fuse or thermostat can interrupt the heating circuit, preventing the dryer from heating properly. These safety components can blow due to overheating or other issues.
-
-
Faulty Igniter (Gas Dryers):
-
Gas dryers use an igniter to ignite the gas and create heat. The dryer won't heat up if the igniter is faulty or not functioning.
-
-
Blocked Ventilation or Lint Filter:
-
A clogged ventilation system or lint filter can restrict airflow, causing the dryer to overheat and trigger safety mechanisms that prevent heating.
-
-
Faulty Gas Valve Solenoid (Gas Dryers):
-
Gas dryers use solenoids to control the flow of gas to the burner. If these solenoids are defective, the burner won't ignite, leading to no heat.
-
Troubleshooting Steps
-
Check the Heating Element:
-
Locate the heating element in your dryer (usually behind the drum or on the rear panel).
-
Use a multimeter to test for continuity. If there is no continuity, replace the heating element.
