Step-by-step troubleshooting

Check the Door Switch
Do: Locate the door switch near the dryer door opening. Use a screwdriver to remove the switch cover and visually inspect the switch for damage or wear.
Observe: The door switch may be cracked, burned, or not closing properly.
Means: A faulty door switch prevents the dryer from starting for safety reasons.
Next: Test the door switch with a multimeter for continuity.
Test the Door Switch
Do: Set your multimeter to the continuity setting. Touch the probes to the switch terminals while gently pressing the switch.
Observe: The multimeter should beep or show continuity when the switch is pressed.
Means: No continuity means the door switch is faulty and needs replacement.
Next: Replace the door switch if it's faulty.
Inspect the Thermal Fuse
Do: Locate the thermal fuse, usually near the dryer's exhaust duct. Use a screwdriver to remove the fuse from its housing.
Observe: The thermal fuse may be blackened or show signs of burning.
Means: A blown thermal fuse is a common cause of dryers not starting due to overheating.
Next: Test the thermal fuse with a multimeter.
Test the Thermal Fuse
Do: Set your multimeter to the continuity setting. Touch the probes to the fuse terminals.
Observe: The multimeter should beep or show continuity if the fuse is good.
Means: No continuity means the thermal fuse is blown and needs replacement.
Next: Replace the thermal fuse if it's blown.
Check the Start Switch
Do: Locate the start switch on the dryer's control panel. Use a screwdriver to remove the switch cover and visually inspect the switch.
Observe: The start switch may be damaged or not making proper contact.
Means: A faulty start switch can prevent the dryer from starting.
Next: Test the start switch with a multimeter.
Test the Start Switch
Do: Set your multimeter to the continuity setting. Touch the probes to the switch terminals while pressing the switch.
Observe: The multimeter should beep or show continuity when the switch is pressed.
Means: No continuity means the start switch is faulty and needs replacement.
Next: Replace the start switch if it's faulty.
Check the Motor
Do: Locate the dryer motor, usually at the bottom of the dryer. Use a screwdriver to remove the motor cover and visually inspect the motor for damage.
Observe: The motor may be burned out or have broken wires.
Means: A faulty motor can prevent the dryer from starting.
Next: Test the motor with a multimeter.
Test the Motor
Do: Set your multimeter to the continuity setting. Touch the probes to the motor terminals.
Observe: The multimeter should beep or show continuity if the motor is good.
Means: No continuity means the motor is faulty and needs replacement.
Next: Replace the motor if it's faulty.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Door Switch The door switch ensures the dryer door is closed before operation. A damaged switch can prevent the dryer from starting.	Common	Easy	Door Switch

FAQ

Why does my Kenmore dryer have power but won't start?

Common causes include a faulty door switch, blown thermal fuse, or damaged start switch. These components are safety features that prevent the dryer from operating when not properly closed or overheated.

Can I bypass the thermal fuse to test the dryer?

No, bypassing the thermal fuse is unsafe and can lead to overheating or fire. Always replace a blown thermal fuse with a new one.

How do I know if the dryer motor is bad?

A bad motor may produce a humming sound without the drum turning, or there may be no sound at all. Testing with a multimeter can confirm if the motor has continuity.

Is it worth repairing an old Kenmore dryer?

If the repair cost is less than half the price of a new dryer, it's usually worth repairing. Otherwise, consider replacing the dryer.

Where can I find replacement parts for my Kenmore dryer?

You can find genuine Kenmore replacement parts at Sears PartsDirect, Amazon, or local appliance repair stores. Ensure the part matches your dryer's model number.
