Samsung Dryer WW02F00173, Replaces WE4M160
The high limit thermostat is your dryer's last line of defence against overheating. When part WW02F00173 fails, the dryer either shuts off mid-cycle to prevent a fire, or worse — stops cutting out entirely, allowing the drum to overheat and damage clothing or internal components. This is a safety-critical repair that should not be deferred.

- Type: High Limit Thermostat (Thermal Cutoff)
- Brand Fit: Samsung
- Function: Monitors exhaust temperature and cuts power to the heating element if a safe threshold is exceeded
- Note: This part is No Longer Available (NLA) from the OEM — stock is limited to available used units
- Skill Level: Intermediate DIY — requires accessing the rear panel or drum assembly depending on model
- Always disconnect power before beginning any repair
- Tools needed: Phillips screwdriver, 1/4" nut driver, multimeter (recommended to confirm failure before ordering)
- Test the old thermostat with a multimeter — should show continuity at room temperature; no continuity confirms failure
- Do not bypass or jumper the thermostat — this is a fire safety component
- Clear lint from the exhaust duct before reassembly
A failed high limit thermostat is often a symptom, not the root cause. Restricted airflow from a clogged lint trap or kinked exhaust duct is the #1 reason this part fails prematurely. Before installing the replacement, clear the full exhaust path and test the cycling thermostat and heating element — replacing only the high limit without addressing airflow will result in repeat failure within weeks.
