A dryer that won't spin is almost never the motor. In most cases it's a broken drive belt, a worn idler pulley, a failed door switch, or seized drum rollers. We diagnose the exact cause first — and the wrong part swap on a 10-year-old dryer can cost you a perfectly good machine.

Quick answer
If your dryer won't spin, 5 causes cover ~95% of what we find: (1) broken drive belt — most common, $185–$255; (2) failed door switch (motor won't start at all) — $145–$215; (3) seized drum rollers or glides — drum tries but binds, $215–$315; (4) worn idler pulley — belt is loose or jumped, $195–$285; (5) failed drive motor or start capacitor — $245–$385. We diagnose first, then quote in writing. Flat $149 trip fee waived on approval. 1-year written warranty.
Root causes, ranked by what we find
What it is: Motor hums and runs, but the drum sits still. The thin rubber belt that wraps the drum has snapped — typically a 6–10 year wear item. Often you'll hear the motor running freely with no resistance.
Fix: Replace OEM drive belt, inspect idler tension, verify drum rotation under full load.
Typical all-in: $185–$255 all-in
What it is: Press start — silence, or a single click. The door-closed safety switch has failed. Easy to miss because the door looks and feels normal when closed.
Fix: Replace OEM door switch assembly. Test continuity in closed and open positions.
Typical all-in: $145–$215 all-in
What it is: Motor runs, belt is intact, but the drum either won't turn or turns with a loud thump-thump. The rear drum rollers (or front glides on some Whirlpool/Maytag platforms) have worn or seized. Common at 8–12 years.
Fix: Replace OEM drum roller kit (both rollers as a pair) and the idler pulley shaft if worn. Verify smooth rotation by hand.
Typical all-in: $215–$315 all-in
What it is: Belt is intact but loose, or has jumped off the motor pulley. The spring-loaded idler that maintains belt tension has worn or seized. Often diagnosed alongside roller failure.
Fix: Replace OEM idler pulley assembly, re-route belt, verify tension under load.
Typical all-in: $195–$285 all-in
What it is: Motor hums hard then trips the thermal cutout, or makes no sound at all (with door switch verified). Either the motor's start winding has failed or the start capacitor (on capacitor-start models) is open.
Fix: Test capacitor first ($25 part). If motor is the failure point, replace OEM drive motor. We quote against replacement honestly on 10+ year units.
Typical all-in: $245–$385 all-in

|---|---|---|
| Hums 2 seconds then stops | Broken drive belt | Belt + idler |
| Hums + drum won't budge by hand | Motor coupler or seized blower wheel | Motor coupler |
| Squeals and won't turn | Idler pulley seized | Idler |
| Display lit, beeps, no motor | Door switch / start switch failed | Switches |
| Spins by hand freely with no resistance | Belt is broken — 100% confirmed | Belt replacement |
| Spins one rotation then stops | Bearing seized; motor overload trip | Drum bearing |
| Burning smell, no spin | Belt slipping on stuck blower or motor | Diagnostic |
| LG 'tE' / 'd80' with no spin | Thermistor / vent-flow code | LG dryer |

Diagnostic order
Open the door and depress the switch plunger by hand while pressing start. If the motor now runs, the door switch (or strike) is at fault. 30-second test before you open anything.
Silence = electrical (door switch, thermal fuse, start switch). Humming with no spin = belt or seized drum. Running smoothly with no spin = broken belt.
With power off and door open, rotate the drum by hand. Free, smooth = motor or belt. Heavy or thumping = rollers/glides. Won't move at all = belt wrapped around something or drum seized.
Two screws at the front edge of the top. Lift the lid. A snapped belt is obvious. A belt jumped off the idler is the second-most-common find.
With the belt off, spin the empty drum by hand. Smooth = rollers fine. Notchy or noisy = roller kit. Don't replace one roller — always do the pair.
FAQs
Belt, door switch, and idler repairs ($145–$285) are worth it on almost any dryer under 15 years. Motor or full roller-and-glide rebuilds on a 12+ year unit sometimes pencil against replacement — we give you the honest math in writing.
Belt and door switch: 30–45 minutes on-site. Roller kit and idler: 60–90 minutes. Motor: 90 minutes. Almost every dryer no-spin repair is done in one visit with truck stock — we carry OEM belts, switches, and roller kits for Whirlpool, Maytag, Samsung, LG, GE, and Electrolux platforms.
No — if the motor hums without spinning, the thermal cutout will trip and may permanently damage the start winding. Unplug it. A $185 belt repair can become a $385 motor repair fast if the motor keeps trying to start against a seized drum.
Most no-spin repairs land $145–$315 all-in. Motor work runs $245–$385. Flat $149 trip fee is credited to whatever repair you approve. We diagnose first, written quote before any work.
Both. Gas dryers add an extra diagnostic step (we verify the gas valve coils and igniter), but the mechanical no-spin causes are identical between gas and electric platforms.
Whirlpool, Maytag, Kenmore (built on Whirlpool platform), Samsung, LG, GE, Electrolux, Frigidaire, Speed Queen, and Bosch. Common no-spin parts (belts, door switches, roller kits) are stocked on the truck for every major platform.
No — the heating element still energizes briefly and a stuck drum builds heat fast. Cabinet damage and fire risk.
Belt + idler kit $245–$345 all-in. 45-minute repair. Trip $149 waived on approval.
