Symptom → what to identify next
These are diagnosis paths for the reviewed components, not failure-rate rankings or a diagnosis of your appliance. Disconnect power before inspection; electrical tests and uncertain repairs belong with a qualified technician.
| What you observe | Next check | Separate references |
|---|---|---|
| Drum does not turn | With power disconnected, inspect the belt and idler for damage or binding. A motor, switch or safety-control fault can also stop operation; do not infer the failed part from the symptom alone. | |
| Dryer runs without heat | Have a qualified technician diagnose the supply, airflow and heater circuit. An open element and an open safety control require different repairs. | |
| Dryer will not start or has overheated | Have the blower-housing fuse checked with power disconnected and investigate the overheating cause. Never bypass a thermal fuse or thermostat. |
Model diagrams and source evidence
Open the complete-model catalog below, choose the diagram for the component, and match its item number. Diagram labels distinguish the blower fuse from the heater safety thermostat and the belt from its tensioning pulley.
These catalogs provide diagrams and part references for the complete model. Check current retailer stock and prices directly. For service procedures, use the manufacturer manual that matches your own appliance label.
| Reference | Package distinction | Exact-model evidence |
|---|---|---|
| 279838 | One 240 V, 5400 W electric-dryer heating element assembly. The high-limit thermostat is a separate reference. | |
| 341241 | One 92-1/4 inch, four-rib dryer drum belt. Pulley, rollers and motor are separate. | |
| WP3392519 | One non-resettable thermal fuse for the blower housing. This is separate from the heater-housing high-limit thermostat. | |
| WP3977767 | One heater high-limit thermostat with terminal extension arm. This is not the blower thermal fuse or a complete cut-off kit. | |
| WP691366 | Dryer Idler Pulley Assembly |
Before you order
