Protect your dryer and ensure safe heating operation with the genuine OEM thermal fuse WP 3399849. This one-time-use thermal cut-out is designed for select Whirlpool-family, Maytag and Kenmore dryer models. If the dryer overheats (often due to blocked venting, lint build-up or failed thermostat), this fuse opens the circuit to shut off the heating element and prevent damage or fire risk.

Before ordering:
-
Verify your dryer’s model number and serial number (usually found on the door jamb or rear panel).
-
Confirm the existing fuse’s rating, terminal type and mounting location to ensure correct match.
-
If the fuse blew due to restricted venting, lint accumulation or other airflow issues, simply replacing the fuse may not solve the root problem — ventilation/maintenance may be required.
