LG Washer Thermistor Assembly Parts — Models & Compatibility

Your LG washer won't start, and you've already checked the obvious stuff — door's closed, water's on, breaker's fine. The thermistor might be your culprit. This temperature sensor tells your washer's control board when water's the right temp, and when it fails, the machine refuses to run. This hub covers the 6322FR2046C thermistor assembly that fits over 100 LG and Kenmore front-load washer models from the WM and WD series.

Is This the Right Part for Your Model?

Your model number's on a sticker inside the door frame or behind the detergent drawer. LG uses a letter-number combo like WM2277HW or WD13513BDM. This thermistor works across multiple series — the WM0532, WM2032, WM2233, WM2277, WM2432, WM2442, WM2455, WM2487, WM2688, WM1814, WM1832, WM2240, WM2250, WM3370, WM3987, WD1460, WD12430, and WD13513 models are all compatible. Check the full list below to confirm your exact model.

About This Replacement Part

The thermistor assembly (part number 6322FR2046C) mounts inside your washer drum near the heater element. It's a simple probe with two wires that measures water temperature throughout the cycle. When it shorts or develops an open circuit, your washer's control board can't verify safe operating temps and shuts everything down before the cycle starts. You'll see all your lights come on, maybe hear a click, then nothing. Some machines throw an error code, but plenty just sit there looking normal while refusing to fill. This part replaces older versions 6322FR2046B, 6322FR2046F, and 6322FR2046W, plus cross-references to AP4445159 and PS3528953.

Installation Overview

You'll need to remove the front panel to access the thermistor. It clips into a bracket near the bottom of the drum. Two wire connections — pull them straight off, don't twist. The new sensor slides right into the same bracket. Takes about 30 minutes if you've got the right screwdriver set. Make sure you unplug the machine first and shut off the water supply.

Why This Part Fails

Thermistors fail from heat cycling and moisture exposure. LG washers run hot wash cycles constantly, and that probe sits right next to the heating element. After a few years, the sensor's resistance drifts out of spec or the wiring connection corrodes. Sometimes detergent residue creeps into the connector and causes intermittent failures. If your washer's been sitting unused for months, moisture can corrode the contacts too.
