Won't spin or agitate

The blower fan is secured with a 14mm nut. To remove, lock the blower wheel with a screwdriver to prevent rotation, then use a 14mm socket with a 6-inch extension to remove the nut. This is a common stumbling point -- without the proper tool and technique, the fan will just spin when you try to unscrew the nut.

Normal sounds include: coins or loose buttons rattling, gas valve or heating element cycling on and off, humming from high-velocity air moving through drum/fan/exhaust. The dryer should be leveled properly to minimize vibration. Abnormal noises include: excessive thumping (worn drum rollers), roaring (blower wheel rubbing housing or bad motor bearings), squealing (sticky or frayed belt), and persistent vibration (dryer not level).

After installing the dryer, use Smart Install mode to verify everything works: Press Adjust Time Up + Temp for 7 seconds. Display shows 'SC'. It tests the moisture sensor (touch sensor shows 0 for open, 1 for wet cloth) and the motor/heater (press Start -- 'OK' means pass, 'HC' means fail). This is much faster than running a full cycle to verify installation.

When diagnosing abnormal motor-area noise, check the spring plates on the Motor-Bracket before condemning the motor. If the spring plates have separated or become loose, the motor will vibrate excessively and create noise. This is a common overlooked cause of motor-area noise that does not require motor replacement -- just reattach or replace the spring plates using long-nose pliers.
