How to Replace a Dryer Motor
To replace a dryer motor, unplug the dryer, open the cabinet, remove the belt and drum as needed, transfer the blower wheel or mounting hardware if required, install the new motor, then reassemble and test the dryer.
A failed dryer motor can keep the drum from turning, make a loud humming sound, or cause the dryer to start and stop. This repair takes some disassembly, but it is manageable if you work slowly, keep track of screws, and confirm the motor is really the problem before swapping parts.
Before you start: Match the replacement part to your exact dryer before ordering.
Safety first
- Unplug the dryer before opening any panels or touching internal wiring.
- Wear gloves because dryer cabinet edges can be sharp.
- Support the drum carefully during removal so it does not damage the felt seals or your hands.
- Do not force the blower wheel or motor clips. If parts are stuck, reassess before cracking a housing or bending a mount.

Step-by-step fix
Step 1: Confirm the motor is the likely problem
- Unplug the dryer and pull it forward enough to reach the vent and power cord safely.
- Try turning the drum by hand. It should move with some resistance, but it should not feel locked solid.
- Think about the symptom pattern. A bad motor often hums without starting, struggles to restart after heating up, or runs briefly and then stops.
- Rule out simpler causes while you are here: make sure the dryer is not overloaded, the vent is not badly crushed, and the drum is not jammed by a fallen item.
- If the belt is broken, badly frayed, or off the pulley, address that first because a motor may not be the root cause.
If it works: The symptoms point to a failed or failing motor rather than a simple belt or airflow issue.
If it doesn’t: If the drum turns normally and the dryer is completely dead, check other likely causes such as power supply, door switch, or thermal safety parts before replacing the motor.
Stop if:
- You smell burned wiring, see melted connectors, or find obvious electrical damage inside the dryer.
- The drum is seized, the blower housing is broken, or the cabinet has major damage that makes this more than a motor swap.
Step 2: Open the dryer and expose the motor area
- Disconnect the vent if needed so you can move the dryer and work comfortably.
- Remove the access panel, top, front, or rear panel as required on your dryer to reach the drum and motor area.
- Set screws aside in small groups so reassembly is easier.
- Take clear photos of the belt path, motor wiring, and any clips or brackets before removing anything.
- Vacuum loose lint from the cabinet so you can see the parts clearly.
If it works: You can clearly see the drum support area, belt path, and motor assembly.
If it doesn’t: If you still cannot reach the motor, continue removing the next cabinet panel needed for access and keep photographing each stage.
Stop if:
- You cannot access the motor without forcing panels or bending the cabinet.
- You uncover severe lint buildup around scorched wires or signs of overheating that need further diagnosis first.
Step 3: Remove the belt and drum
- Release belt tension from the idler pulley and slip the belt off the motor pulley.
- Use the belt as a handle to help lift and slide the drum out if your dryer design requires full drum removal for motor access.
- If the drum does not need to come fully out, move it only as far as needed to reach the motor safely.
- Inspect the belt, idler pulley, and drum rollers while the drum is out. Replace worn parts now if they are rough, cracked, or noisy.
If it works: The drum and belt are out of the way, and the motor is fully accessible.
If it doesn’t: If the belt routing is confusing, use your photos to retrace it before going further so reassembly is easier later.
Stop if:
- The drum support rollers, shafts, or idler bracket are badly worn or damaged enough to keep the dryer from operating correctly after the motor is replaced.
Step 4: Remove the old motor
- Disconnect the motor wire harness or individual wire connectors, using your photos as a guide.
- Remove any retaining clips, brackets, or mounting fasteners that hold the motor in place.
- If the blower wheel is attached to the motor shaft, hold the motor shaft as needed and remove the blower wheel carefully without cracking it.
- Lift the old motor out and compare it side by side with the new one, checking shaft length, mounting points, and connector layout.
- Transfer any reusable mounting pieces, clamps, or spacers from the old motor to the new one if your dryer uses them.
If it works: The old motor is out, and the new motor matches the original well enough to install.
If it doesn’t: If the new motor does not match the old one, stop and verify the replacement using your dryer's exact model information before installing it.
Stop if:
- The blower wheel is stripped, cracked, or fused to the shaft and cannot be reused safely.
- The replacement motor has different mounting points or electrical connections that do not match your dryer.
Step 5: Install the new motor and reassemble the dryer
- Set the new motor into place and secure it with the original clips, bracket, or fasteners.
- Reconnect the wiring exactly as it was before removal.
- Reinstall the blower wheel if it was removed, making sure it spins freely without rubbing the housing.
- Put the drum back in place, route the belt around the drum, and reinstall the belt on the motor pulley and idler pulley.
- Rotate the drum by hand several turns to make sure the belt tracks correctly and nothing binds.
- Reinstall the cabinet panels and reconnect the vent.
If it works: The dryer is fully reassembled, and the drum turns by hand without scraping or binding.
If it doesn’t: If the drum is hard to turn or the belt slips off, reopen the dryer and correct the belt routing or drum seating before testing with power.
Stop if:
- The blower wheel rubs badly, the drum binds, or the motor mount will not hold securely.
Step 6: Test the repair under real use
- Plug the dryer back in and run it empty for a minute or two first.
- Listen for smooth startup, steady drum rotation, and normal airflow at the exhaust.
- If that sounds good, dry a small load of laundry and let the dryer run long enough to confirm it keeps tumbling without stopping.
- Check again for unusual humming, burning smells, scraping, or weak airflow after the dryer warms up.
If it works: The dryer starts normally, keeps running, tumbles the load, and does not show the original motor-related symptoms.
If it doesn’t: If the dryer still hums, stops after warming up, or will not turn the drum, continue diagnosis for a seized blower wheel, wiring issue, belt problem, or another failed component.
Stop if:
- You notice smoke, a strong burning smell, sparking, or the dryer trips power during the test.

FAQ
What are common signs of a bad dryer motor?
Common signs include a humming sound without drum movement, a dryer that starts only if you spin the drum by hand, a unit that stops after warming up, or a motor that sounds rough and noisy.
Do I always have to remove the drum to replace the motor?
Often yes, but not always. Many dryers need the belt and drum removed for clear access to the motor. Some designs allow partial access with less disassembly.
Should I replace the belt at the same time?
If the belt is worn, glazed, cracked, or stretched, it is smart to replace it while the dryer is already apart. The same goes for noisy idler pulleys or worn drum rollers.
Why does my dryer motor hum but not start?
That can happen when the motor windings are failing, the motor is overheating, the blower wheel is jammed, or the drum is hard to turn because of another mechanical problem. Confirm the drum and blower move freely before blaming the motor.
Can a clogged vent look like a bad motor?
A badly restricted vent can overheat the dryer and contribute to shutdowns, but it usually does not cause a locked or humming motor by itself. It is still worth checking before and after the repair.
