LG Dishwasher Sensor & Thermistor Parts

LG Dishwasher Sensor and Thermistor Parts

Water temperature sensors and thermistors are critical to proper LG dishwasher operation. These parts monitor water temperature and communicate with the control board to ensure cycles run at the correct heat levels. When a thermistor fails, you'll notice poor cleaning performance, water that's too hot or cold, or error codes on the display.

A faulty sensor won't always trigger an obvious failure — sometimes the dishwasher runs but produces lackluster results because it can't regulate temperature properly. The good news is that OEM LG thermistors are affordable ($20 to $50) and straightforward to replace. Repair Clinic carries genuine LG sensors for all major model series, from the LDTS series to factory-certified LG models.

• No heat during wash cycle: water stays cold; thermistor sends wrong signal to heating element
• Water too hot or inconsistent temperature: sensor miscalibrates; control board can't adjust properly
• Poor drying performance: heated dry cycle won't engage because sensor reports incorrect temp
• Error codes on display: many LG models flash error when thermistor circuit fails
• Spotty or cloudy dishes: water temperature too low to activate detergent properly

Find your LG dishwasher model number and browse the exact thermistor or temperature sensor your model needs. OEM sensors maintain the precise resistance calibration your control board expects.

LG Dishwasher Thermistor and Sensor FAQ

Why does my LG dishwasher run but dishes come out cold and wet?

The heating element may be firing, but if the thermistor has failed, the control board won't know the water temperature and can't properly manage the heat cycle. A weak or failed sensor tells the board the water is already hot, so it never signals the heating element to turn on. Replace the thermistor first — it's cheap and a common culprit.

How do I find my LG dishwasher model number to order the correct sensor?

Your model number is printed on a white sticker inside the door edge (look along the top or sides) or on the side wall of the tub. It starts with letters like LDTS, LDT, or LDTE followed by numbers. Write down the complete model number and enter it into Repair Clinic's parts lookup. The system will show you the exact thermistor and all compatible sensors for your specific LG model.

Is a thermistor the same as a temperature sensor on LG dishwashers?

They work the same way — both are temperature-sensing thermistors that change electrical resistance as water temperature changes. LG uses the terms interchangeably in some documentation. What matters is that you match the part number to your model. An OEM LG thermistor is engineered to the exact resistance curve your control board expects.

Can I replace an LG dishwasher thermistor myself?

Most LG thermistors screw or clip into a well at the bottom of the tub or on the spray arm housing. It's usually a 5 to 15 minute job with no special tools. Consult your model's parts diagram on Repair Clinic to confirm location and connector type. Once you order the OEM part, disconnect the old sensor, snap or screw in the new one, and reconnect the wire harness.

LG Dishwasher Model Number: Where to Look

On LG dishwashers, look for the model number on a label along the inside edge of the door or on the side wall of the tub. Open the door fully and check the top and side edges, then inspect the tub wall if the label is not easy to spot. Copy the complete model number, including any suffix after a slash or additional characters. Enter it in the model number search to pull up the parts matched to your unit. This filters Repair Clinic's full LG dishwasher catalog, not just sensors or thermistors, so the results are tied to your specific dishwasher model. You can confirm fit faster and avoid sorting through incompatible listings.
