IFB Refrigerator THERMOSTAT FF TYPE 3 (1 DEG WARMER)

The IFB Frost Free Refrigerator Type 3 Thermostat Sensor (Part Number: RF221ELTST003) is an authentic original equipment manufacturer (OEM) replacement temperature sensor designed for select IFB frost-free refrigeration systems. Featuring a specialized Type 3 resistance profile calibrated for a 1°C warmer operating offset compared to standard sensors, this component continuously monitors internal cabinet or evaporator temperatures. It relays precise thermal resistance data to the main refrigerator control board, ensuring accurate compressor cycling and balanced humidity retention.

Key Features

• Type 3 Calibrated Profile (+1°C Warmer Offset): Engineered specifically to maintain a slightly warmer storage environment, preventing items from freezing or frosting in sensitive compartments.

• High-Precision NTC Thermistor: Delivers accurate, rapid thermal response across wide temperature ranges to maintain strict operational thresholds.

• Hermetically Sealed Waterproof Tip: Epoxy or stainless steel probe housing protects the internal sensing element from high humidity, condensation, and frost exposure.

• Flexible Insulated Lead Wire: Durable PVC or silicone-sheathed wiring resists hardening, cracking, and electrical interference under low-temperature conditions.

• Precision Plug-in Terminal Connector: Factory-molded multi-pin connector ensures a secure, low-resistance plug-and-play attachment to the main wiring harness.

Benefits

• Solves symptoms such as food items freezing in the refrigerator section, erratic compressor cooling cycles, incorrect temperature readings, or sensor-related error codes.

• Replaces drifted, water-damaged, or short-circuited thermostat probes.

• Direct OEM replacement guarantees exact electrical resistance curves, correct +1°C offset timing, and seamless mounting clip alignment.

Applications

Designed specifically for select IFB frost-free refrigeration models requiring Type 3 thermostat sensor part number RF221ELTST003.

What's Included

• 1 x Genuine IFB Frost Free Refrigerator Type 3 Thermostat Sensor Probe (RF221ELTST003)

Usage Instructions

• Warning: Unplug the refrigerator completely from the electrical wall outlet before beginning any repair work.

• Locate the existing thermostat sensor probe inside the refrigerated compartment or secured along the evaporator line.

• Disconnect the wiring harness plug leading from the old sensor to the main control board.

• Unclip or unfasten the sensor probe tip from its mounting bracket or holder.

• Position the new IFB RF221ELTST003 sensor probe into the exact mounting location, ensuring solid thermal contact with the surface it monitors.

• Plug the connector securely into the matching harness port on the control board.

• Reassemble any removed panels, restore power, and test the appliance cycle.

Safety Instructions

• Always isolate electrical power to the appliance before touching internal wiring or sensors.

• Handle the delicate probe tip with care; avoid bending or crushing the sensor bulb during installation.

Care Instructions

• Keep the sensor tip free from heavy frost, lint, or food residue buildup to maintain accurate thermal conductivity.
