Manufacturer Part Numbers / Cross-References: R9900489
What This Listing Includes: One genuine OEM R9900489 thermal fuse.
Model Evidence Note: Model-first verification is required; no incomplete model list is presented as a complete fit list.
Compatibility Basis: Exact OEM part number, appliance application and model-first verification.
Correct Part / Compatibility Check: Confirm that R9900489 (or a verified manufacturer cross-reference shown above) is specified for the complete appliance model, then match the exact installation position and identification details before ordering.
Distinguish From Similar Parts: Thermal fuses, high-limit thermostats and cycling thermostats may mount nearby but have different ratings and functions.
Possible Related Symptoms / Reasons to Inspect: A no-start or no-heat condition may justify continuity testing, but a blown fuse also requires checking airflow and the cause of overheating.
Important Safety / Service Note: Disconnect dryer power before testing/replacement. Never bypass a thermal fuse; correct the underlying overheating or airflow problem.
Ordering Note: Symptoms can identify a system to inspect, but they do not prove this specific component is defective. Confirm the exact OEM part number and model-specific parts diagram/service information before ordering.
