Samsung Dryer High Limit Thermostat Parts — Models & Compatibility

Your Samsung dryer suddenly stopped heating, or worse — it's overheating and shutting off mid-cycle. The high-limit thermostat (DC47-00018A) is Samsung's fail-safe component that cuts power when temperatures climb too high. This hub covers replacement thermostats for Samsung and Kenmore-branded Samsung dryers from the DV200 through DV400 series.

Is This the Right Part for Your Model?

Before ordering, you'll need your dryer's exact model number. For Samsung dryers, look inside the door frame or on the back panel near the power cord. The model number typically starts with "DV" followed by numbers and letters (like DV218AEW/XAA). This thermostat replaces part numbers AP4201898, PS4205217, and 35001092 across multiple model years.

About This Replacement Part

The high-limit thermostat acts as your dryer's temperature guardian. When internal temps exceed safe levels — usually around 280-300°F — it breaks the circuit to prevent fire hazards. Most failures happen because something else went wrong first: a clogged vent restricts airflow, the blower wheel gets jammed, or the heating element cycles too aggressively. The thermostat sacrifices itself to protect your home. If your dryer won't heat at all after a shutdown, this component has likely opened permanently and needs replacement. It's a small disc-shaped device mounted on the heating element housing, typically held in place with two screws and connected by two wire terminals.

Common Failure Scenarios

The high-limit thermostat may fail if the dryer overheats, causing it to cut off power and prevent heating. You'll know it's failed when the dryer runs normally — drum turns, timer advances, everything looks fine — except there's zero heat. Sometimes it fails intermittently, heating for a few minutes before cutting out. If you've already replaced it once and it failed again quickly, you've got a ventilation problem that needs addressing before installing another thermostat.

What You Need to Know Before Replacing

This is a straightforward repair for most DIYers. You'll need to access the dryer's rear panel (front-load models) or remove the front panel (some top-access designs). The thermostat sits directly on or near the heating element housing. Disconnect power, locate the failed thermostat, remove two wire connectors, unscrew the mounting screws, and reverse the process with your new part. The entire job takes 15-30 minutes once you've got the panel off.

Why It Matters

A functioning high-limit thermostat isn't optional — it's a critical safety device. Operating a dryer with a bypassed or missing thermostat creates serious fire risk. If you're tempted to "test" the dryer by jumping the thermostat connections, don't. Install the proper replacement part and address whatever caused the original failure. Check your vent system, clean the blower housing, and verify the heating element isn't shorted to ground.
