Parts for Maytag JS48NXFXDW04: 03 - Refrigerator Liner Parts

A thermistor assembly that measures refrigerator temperature and sends that data to the control board so the appliance can regulate cooling. Replaces a failed sensor to help restore accurate temperature control. What it does:

• Senses internal temperature and converts it to a signal the control board uses to adjust cooling.
• Helps regulate compressor, evaporator, and defrost cycles when operating correctly.
• Common symptom: erratic or incorrect refrigerator/freezer temperatures.
• Common symptom: cooling failure, long run times, or temperature-related error codes.

• Disconnect power before accessing or replacing the thermistor to avoid shock.
• Handle the sensor element and wiring gently; avoid pinching or crimping the leads.
• Install in the same location and orientation shown in the OEM diagram for reliable readings.

This replacement screw secures appliance panels and components to restore proper fit and stop loose or rattling parts. A simple, OEM-compatible fastener that helps maintain safe, stable operation and original assembly alignment. What it does:

• Secures panels, trim, brackets or components to prevent movement and vibration
• Restores proper fit when a screw is missing or stripped
• Helps eliminate rattling, gaps, or misaligned parts
• Fits the OEM threaded holes and fastening points

• Disconnect power (and gas if applicable) before accessing internal components
• Use the correct driver to avoid stripping the head; hand-start threads before final tightening
• Do not overtighten—stop when snug to avoid damaging threads or plastic parts
• Keep removed hardware organized to ensure correct reassembly

This screw is used to secure the handle end cap to the center of the door. The screw size measures 8-18 x 1/2 inches.

This air baffle assembly regulates and directs cold airflow inside the refrigerator, typically between the freezer and fresh food sections. Replacing a damaged baffle helps restore balanced air distribution for more even cooling and stable temperatures throughout. What it does:

• Controls the amount and direction of airflow to maintain set temperatures
• Helps reduce warm spots or over-cooling in the fresh food compartment
• A cracked, missing, or misaligned baffle may lead to a warm refrigerator while the freezer stays cold
• Air leaks or obstruction at the baffle can cause frost or unusual air noise near the vent

• 1 air baffle assembly

• Disconnect power to the refrigerator before servicing
• Remove shelves and the interior vent/diffuser cover to access the baffle
• Retain and transfer any screws, clips, or seals from the original part as required
• Seat the new baffle fully so the seal engages evenly; reassemble and verify airflow

The Thermistor is an OEM replacement part for Whirlpool refrigerators. This temperature-sensitive sensor monitors conditions inside refrigerator and freezer compartments. It provides critical feedback to the electronic control module, regulating cool air temperature in both sections.

Symptoms of a faulty thermistor include:

• Fluctuating temperatures where sections become too warm or cold  
• Frequent cycling of evaporator fans and cooling components
• Defrost issues or Er/Ed error codes shown on displays

Causes can involve regular exposure to changing interior environments over many years. Mineral deposits accumulating may lead to sensor surfaces becoming insulated. Physical stress from overloading could potentially crack the thermistor over time as well. 

This OEM replacement part is compatible with some Kenmore Elite models too.
