Component Locations
Control Panel Assembly
Located at the top front of dryer. Contains user interface, main control board, and selector switches. Access by removing top panel.
Drive Motor
Located at the bottom front of dryer cabinet. Drives drum rotation and blower wheel. Access through front or bottom panel.
Heating System
Electric: Heating element located in rear ducting. Gas: Burner assembly at bottom rear. Both require careful access procedures.
Thermal Fuse
Located on dryer exhaust duct near heating element. Critical safety device that cuts power if overheating occurs.
Thermistor
Mounted in dryer exhaust duct. Monitors air temperature and communicates with main control board for temperature regulation.
Belt & Idler Pulley
Belt wraps around drum and motor pulley. Idler pulley maintains tension. Located under drum access through front panel.

Repair Procedures
| Problem | Possible Cause | Solution |
|---|---|---|
| Dryer won't start | Power issue, door switch failure, thermal fuse blown | Check power supply, test door switch, replace thermal fuse |
| No heat | Heating element failure, thermal fuse, thermostat issue | Test heating element continuity, check thermal fuse, verify thermostat operation |
| Drum not turning | Belt broken, motor failure, idler pulley seized | Inspect drive belt, test motor operation, check idler pulley |
| Overheating | Vent blockage, thermistor failure, cycling thermostat | Clean vent system, test thermistor, replace cycling thermostat |
| Unusual noises | Worn rollers, blower wheel obstruction, idler pulley | Inspect drum rollers, check blower wheel, lubricate idler pulley |
| Error codes displayed | Sensor failure, control board issue, wiring problems | Diagnose specific error code, test sensors, check wiring connections |
Step-by-Step Common Repairs
- Thermal Fuse Replacement: Disconnect power, remove rear panel, locate fuse on exhaust duct, test continuity, replace if open circuit
- Drive Belt Replacement: Remove front panel, release belt tension, remove old belt, route new belt properly, reassemble and test
- Heating Element Replacement: Disconnect power, access rear heating chamber, disconnect wires, remove mounting screws, install new element
- Drum Roller Replacement: Remove front and top panels, lift drum, replace worn rollers, reassemble and verify smooth rotation
- Thermistor Replacement: Access through rear panel or exhaust duct, disconnect wiring harness, remove mounting clip, install new sensor
