Is your dryer not turning on, even though everything seems fine? At Houston Home Fix, we specialize in dryer repair in Houston, and we know exactly how frustrating it is when your dryer won’t start — especially if the laundry is already loaded. Below, we’ve outlined the 5 most common reasons why your dryer won’t start, along with tips on how to diagnose and fix each one. Whether you’re dealing with a dryer not heating in Houston or one that simply won’t power on, this guide will help you understand the problem — and when to call in the pros.
Reasons Why the Dryer Won’t Start
- Door Not Fully Closed or Door Switch Is Broken
- Blown Thermal Fuse
- Faulty Start Switch
- Broken Drive Belt
- Control Board or Timer Malfunction
Door Not Fully Closed or Door Switch Is Broken – №1
Modern dryers are designed with safety in mind. If the door isn’t fully shut or the door switch is faulty, your dryer won’t spin.
Diagnosis
- Listen for a click when you close the door
- Use a multimeter to test the door switch for continuity
Repair
If the switch is physically broken or doesn’t show continuity, replace the door switch.
Replacement cost: from $150
Blown Thermal Fuse – №2
The thermal fuse protects your dryer from overheating. If the vent is clogged or airflow is restricted, the fuse can blow — and the dryer won’t start.
Diagnosis
- Locate the fuse (usually near the blower or exhaust duct) and test it with a multimeter
- A good fuse will have near-zero resistance
Repair
- Replace the blown thermal fuse
- Clean the entire dryer vent system to prevent future issues
Replacement cost: from $230
Faulty Start Switch – №3
The start button may seem simple, but it’s a common failure point — especially in basic GE dryer models where the plastic knob or internal plunger wears out or breaks.
Diagnosis
- Listen for a click when pressing the start button
- Check the switch for continuity with a multimeter
Repair
Replace the start switch or broken knob if needed.
Replacement cost: from $200
Broken Drive Belt – №4
Most dryers won’t start if the drive belt is broken. Some models have a sensor that disables the motor when the belt is damaged.
Diagnosis
- Visually inspect the belt for damage or breakage
- Use a multimeter to test the belt switch (if present) for continuity
Repair
Replace the broken belt or faulty belt switch.
Replacement cost: from $220
Control Board or Timer Malfunction – №5
Depending on your dryer model, the main control board or timer may be responsible for powering on the motor, heater, and display. If either one fails, the dryer won’t start.
Diagnosis
- Check for power reaching the control board
- See if the board or timer is sending voltage to other components
Repair
Replace the control board or timer if they’re not functioning properly.
Diagnosis and replacement cost: from $250
