Samsung Dryer Thermistor Parts — Models & Compatibility

Your Samsung dryer shuts off mid-cycle or runs forever without heating properly? The thermistor — that small temperature sensor mounted near the heating element — is probably sending incorrect readings to your control board. This hub covers the DC32-00007A thermistor that fits over 100 Samsung, Kenmore, and Amana dryer models from the DV series.

Is This the Right Part for Your Model?

Check your dryer's model number label — it's usually inside the door frame or on the back panel near the power cord. Match it against the compatible models list below. This thermistor replaces part numbers AP4201716, PS4204984, and 2068429. If you've got a Samsung DV series dryer (DV40, DV42, DV45, DV48, or DV50), there's a 95% chance this is your part.

About This Replacement Part

The DC32-00007A is a negative temperature coefficient (NTC) thermistor that monitors exhaust air temperature. When it fails, your dryer's control board can't regulate heat cycles properly — you'll get clothes that come out damp after an hour, or the machine shuts down with an error code after 10 minutes. Samsung uses this exact sensor across their entire modern dryer lineup, from basic models like the DV40J3000EW to high-end steam units like the DV50K8600EV. It's a direct OEM-equivalent replacement that mounts with a single clip bracket — no screws, no wire splicing.

Compatible Samsung Dryer Models

This thermistor works with these Samsung dryer series and their variants:

• DV40 Series: DV40J3000EW, DV40J3000EW/A2 (7.2 cu. ft. electric models)
• DV42 Series: DV42H5000EW, DV42H5000EW/A3, DV42H5200EW, DV42H5200GW, DV42H5200GF, DV42H5600EP (mid-range electric)
• DV45 Series: DV45H7000EW, DV45H7000EW/A2 (7.5 cu. ft. steam dryers)
• DV48 Series: DV48H7400GW, DV48J7700EW (large capacity 7.5+ cu. ft.)
• DV50 Series: DV50F9A7EVW, DV50K8600EV (premium 7.5 cu. ft. AddWash models)
• DV448AEP and related sub-variants

Also compatible with Kenmore Elite dryers using Samsung-manufactured chassis (typically model numbers starting with 796.8 or 796.9).

What This Part Does

The thermistor sits in the exhaust duct between your drum and the lint filter housing. As hot air passes over it, its electrical resistance changes — the control board reads that resistance to calculate temperature. When you select "Normal Dry" or "Sensor Dry," the board uses thermistor data to decide when your clothes are actually dry. A failing thermistor reports wonky temps, so the board either cuts heat too early (damp clothes) or runs too long (wasted energy). Sometimes you'll get error codes like tE, tS, or HC on newer models.

Signs You Need This Part

• Dryer stops heating after 5-15 minutes, displays error code
• Runs for 2+ hours but clothes still damp
• Sensor dry cycles don't work — timed dry is the only setting that completes
• Intermittent heating: works fine one load, not the next
• Control panel shows tE (thermistor error) or HC (high current) codes

Installation Overview

You'll need to pull the dryer away from the wall and remove the top panel (usually two screws at the back). The thermistor clips into a plastic bracket on the exhaust duct — squeeze the clip, pull the old sensor out, push the new one in until it clicks. Takes about 15 minutes if you've never opened a dryer before. The wire connector is a simple push-on spade terminal. No special tools beyond a Phillips screwdriver and maybe a 1/4" nut driver.

Why Samsung Thermistors Fail

Lint buildup is the main culprit. When your exhaust vent gets clogged, temperatures spike beyond design limits — 180°F becomes 220°F. The thermistor's internal resistor degrades from repeated thermal stress. Samsung's thermistors are rated for about 8-10 years under normal use, but a restricted vent can kill one in 3 years. If you're replacing this part, clean your entire vent line from the dryer to the outside cap. Otherwise, you'll be back here ordering another thermistor in 18 months.

Verify Before You Order

Look inside your dryer's exhaust duct area — if there's a small black or gray sensor with two wires clipped into a white plastic bracket, that's this part. The part number is sometimes printed on the sensor body, but it's tiny. Easier to just match your model number from the list above. When in doubt, pull the old part out and compare the wire connector style — it should be a 1/4" female spade terminal, not a multi-pin plug.
