🔌 Step 1: Check Power Supply
For Electric Dryers:
- Make sure the dryer is plugged in securely.
- Test the outlet by plugging in another device.
- If it doesn’t work, check your circuit breaker — dryers need two 120V breakers (240V total).
- If one tripped, reset both.
For Gas Dryers:
- Check that the power cord is plugged in (yes, gas dryers still need electricity).
- Ensure the gas valve is open.
🚪 Step 2: Inspect the Door Switch
Dryers won’t start if the door isn’t fully closed or the door switch is faulty.
- Open the door and press the door switch lever — you should hear a click.
- If there’s no click, the switch may be broken.
- Use a multimeter to test continuity.
- If there’s no continuity, replace the door switch.
▶️ Step 3: Test the Start Button or Switch
A worn or broken start button can prevent the dryer from running.
- Unplug the dryer.
- Remove the control panel (check your model’s manual).
- Use a multimeter to test the start switch for continuity when pressed.
- If it fails, replace it.
🌡️ Step 4: Check the Thermal Fuse
The thermal fuse is a safety device that blows if the dryer overheats — and once it blows, the dryer won’t start.
- Locate the fuse (usually on the blower housing or near the heating element).
- Remove one wire and test with a multimeter.
- No continuity = blown fuse.
- Replace it with the exact part number.
💡 Tip: If the fuse blew, check for clogged vents or lint buildup that caused overheating.
🪢 Step 5: Inspect the Drive Belt and Belt Switch
If the belt breaks, the belt switch (on some models) will prevent the motor from running.
- Open the dryer cabinet.
- Check if the belt is intact and properly wrapped around the drum.
- If broken, replace it.
- Test the belt switch with a multimeter for continuity.
⚙️ Step 6: Test the Motor
If you hear a humming noise but the drum doesn’t turn, the motor might be jammed or burned out.
- Check for lint or debris blocking the motor fan.
- Try spinning the drum manually — if it’s hard to turn, the motor may be seized.
- Test the motor windings with a multimeter.
- If it fails, the motor needs replacement.
🧠 Step 7: Check the Timer or Control Board
If all mechanical parts are fine, the problem may be electronic.
- Mechanical timer models:
- Use a multimeter to test the timer contacts for continuity.
- Digital models:
- Look for burnt marks or damaged components on the control board.
- If faulty, replace or have it serviced by a technician.
🧹 Step 8: Clean the Dryer Vents
Even if your dryer starts again, restricted airflow can cause future failures or blown fuses.
- Disconnect the vent hose.
- Vacuum lint from the hose and wall duct.
- Clean the lint trap thoroughly.

Preliminary Checks
Before calling a repair service, several simple issues might be preventing your dryer from starting. These basic checks often solve the problem without requiring professional help or expensive parts.
Check the Power Source
First, verify your dryer is receiving power. For an electric dryer, ensure the plug is fully inserted into the outlet. Try plugging another device into the same outlet to confirm it’s working.
Check your home’s circuit breaker panel. Look for any tripped breakers related to the laundry room. If you find one, flip it completely off before switching it back to the on position.
For a gas dryer, verify that both the electric connection and gas supply valve are functioning. The valve should be parallel to the gas line when open.
If your dryer has a reset button (usually located at the back), press it firmly to reset the internal systems.
Examine the Dryer Door Switch
The door switch acts as a safety device that prevents operation when the door isn’t fully closed. Check that your dryer door closes completely and latches properly.
Listen for a clicking sound when you close the door—this indicates the switch is engaging. If you don’t hear it, the switch might be defective.
Try these troubleshooting steps:
- Clean around the door opening to remove lint buildup
- Check for obstructions in the door latch area
- Press firmly on the door to ensure proper closure
- Inspect the door catch for damage or misalignment
Some dryers have a small button near the door frame that needs to be fully depressed when closed.
Ensure Correct Model and Settings
Verify you’re using your specific dryer model correctly by checking its user manual. The model number is typically found on a label inside the door or on the back of the machine.
Many modern dryers have child lock or control lock features that can prevent starting. Look for a “Control Lock” indicator light on your display panel.
Check these common setting issues:
- Delayed Start: Your dryer might be set to start at a later time
- Specialty Cycles: Some cycles require specific button sequences
- Child Lock: Usually disabled by holding a combination of buttons
- Pause/Start Button: Ensure it’s working properly by pressing firmly
If your dryer has a digital display, look for error codes that might indicate specific problems requiring attention.
Common Causes for Dryers Not Starting
When your dryer refuses to start, several components could be at fault. Understanding these common failure points can help you diagnose the issue without immediately calling a professional repair service.
Faulty Start Switch
The start switch is what activates your dryer when you press the start button. If this component fails, your dryer won’t receive the signal to begin operation.
You can test if your start switch is defective using a multimeter to check for continuity. When pressing the switch, the meter should indicate a complete circuit. If there’s no continuity when pressed, the switch needs replacement.
Signs of a faulty start switch include:
- No response when pressing the start button
- Intermittent starting
- Clicking sound but no operation
Replacing a start switch is relatively straightforward and doesn’t usually require special tools. Most switches can be accessed by removing the control panel, which typically involves a few screws.
Tripped Thermal Fuse
A thermal fuse is a crucial safety device that prevents your dryer from overheating. Once it blows, your dryer won’t start until it’s replaced.
The most common cause of a blown thermal fuse is a clogged dryer vent. When hot air can’t escape properly, the dryer overheats, triggering the fuse. You can test the thermal fuse with a multimeter – a working fuse should show continuity.
To check your thermal fuse:
- Unplug the dryer
- Locate the fuse (usually on the blower housing or exhaust duct)
- Remove and test with a multimeter
- Replace if blown
Always clean your dryer vent when replacing a thermal fuse. Otherwise, the new fuse will likely blow again soon after installation.
Broken Drive Belt
The drive belt wraps around your dryer drum, motor pulley, and idler pulley. When it breaks, the drum won’t spin, and a safety switch may prevent the dryer from starting.
You can check for a broken belt by trying to turn the drum manually. If it spins very freely with little resistance, the belt has likely snapped. Most dryers have a safety feature that prevents operation when the belt breaks.
To replace a drive belt:
- Unplug the dryer
- Remove the front or top panel (varies by model)
- Check the old belt routing
- Install the new belt following the same path
Make sure to purchase the exact replacement belt for your dryer model. An incorrectly sized belt can slip or cause additional damage.
Defective Drive Motor
The drive motor powers both the drum rotation and the blower wheel in most dryers. When it fails, your dryer won’t start or may make unusual noises.
Common signs of a failing motor include:
- Humming noise without drum movement
- Burning smell during operation
- Overheating
- Complete failure to start
You can test the motor by checking for continuity between the motor terminals with a multimeter. If the readings are inconsistent with manufacturer specifications, the motor likely needs replacement.
Motor replacement is one of the more complex dryer repairs. You’ll need to disconnect wiring, remove mounting brackets, and carefully handle the heavy component. This repair might be best left to professionals unless you’re comfortable with more advanced appliance work.
Technical Troubleshooting
When your dryer won’t start, it’s often due to faulty electrical components or internal parts that have worn out or failed. Proper diagnostic testing can help you identify the specific problem without immediately calling an appliance technician.
Testing Electrical Components
Start by checking the power supply to your dryer. Ensure the plug is securely in the outlet and verify that the circuit breaker hasn’t tripped. Use a multimeter to test for continuity in the power cord – damaged cords can prevent power from reaching your dryer.
Next, check the thermal fuse, which is a common safety device that prevents overheating. This small component often fails due to clogged vents. To test it:
- Unplug the dryer
- Locate the thermal fuse (usually on the blower housing or exhaust duct)
- Remove the fuse and test for continuity with a multimeter
- No continuity means it’s blown and needs replacement
The door switch is another critical component. When testing it, press and release the switch several times while checking for continuity. A faulty start switch or timer can also prevent your dryer from starting and should be tested similarly.
Accessing and Assessing Internal Parts
Before examining internal parts, always disconnect power to avoid electric shock. Most dryers have access panels on the back or front that can be removed with a screwdriver.
When your dryer won’t start, inspect these key components:
- Drive belt – A broken belt triggers a safety device that prevents operation
- Motor – Check for free movement and signs of burning
- Heating element – Test for continuity (electric dryers)
- Gas valve solenoids – Listen for clicking when starting (gas dryers)
The drive belt can be checked by turning the drum by hand. If it rotates freely with no resistance, the belt may be broken. To access the motor, you’ll typically need to remove the front panel and drum.
If you smell burning or see visible damage to any component, stop troubleshooting and consult an appliance technician immediately. Some parts like motor centrifugal switches require specialized knowledge to test properly.
Professional Assistance and Repairs
Sometimes your dryer won’t start despite all your troubleshooting efforts. When DIY solutions fail, it’s time to call in a professional.
An appliance technician has specialized tools and experience to diagnose complex electrical issues that might be beyond your reach. They can safely check the motor, control board, and other internal components.
When to call a professional:
- Your dryer remains unresponsive after basic troubleshooting
- You notice burning smells or unusual noises
- The dryer has visible damage to wiring
- You’re uncomfortable working with electrical components
Professional repairs may cost between $100-$400 depending on the issue, but this investment can extend your dryer’s lifespan significantly.
