Description
Refrigerator Compressor Start Relay General Electric (GE) 3ARR3B4AA3 (art. 1.253.014)
Original electromagnetic potential-type start relay (Potential Relay) General Electric 3ARR3B4AA3 (factory code 1.253.014, made in Malaysia) is designed for switching the start winding of single-phase asynchronous motor-compressors in domestic and commercial refrigerators, freezers, ice makers, and display cases. Unlike PTC (thermistor) relays, the 3ARR3 series potential relay operates based on the voltage level across the start winding as the compressor rotor accelerates, ensuring a reliable motor start even under high refrigerant pressure in the system or low mains voltage. The housing features a top mounting eyelet with a mandatory "THIS SIDE UP" installation orientation and screw terminal blocks with terminal numbering 1, 2, 4, 5, and 6.
Key Advantages and Features:
- Original General Electric (GE) Design: Factory calibration of the armature pick-up and drop-out voltage guarantees timely disconnection of the start winding and start capacitor without overheating the compressor.
- Reliable Screw Terminals with Pressure Plates: Five contact pads (terminals 1, 2, 4, 5, 6) with heavy-duty Phillips and slotted head screws provide tight electrical contact for power wires.
- Dielectric Barriers on the Contact Panel: Molded insulating partitions between terminals eliminate arc tracking and short circuits in high-humidity compressor compartments.
- VDE and UL (cRUus) Certification: Complies with international electrical safety standards for continuous operation within refrigeration units.
- Convenient Frame Mounting: A metal mounting bracket with a hole at the top of the housing allows the relay to be rigidly fixed to the refrigerator chassis in a strictly vertical position.
Compatibility and Application:
Used in the starting system of hermetic motor-compressors (primarily with a start capacitor) in refrigeration and HVAC equipment:
- Refrigerators and Freezers: General Electric (GE), Hotpoint, RCA, Kenmore, Whirlpool, Amana, Frigidaire, Sub-Zero (in modifications using the 3ARR3 series potential relay).
- Interchangeable Part Numbers and Cross-References: GE 3ARR3B4AA3, 3ARR3-B4AA3, 1.253.014, WR07X10051, WR07X10055, WR07X0214, AP3185426, PS288856.

Technician's Tip: When installing this relay, it is critical to observe the housing orientation — the metal mounting eyelet labeled "THIS SIDE UP" must be strictly at the top, as the operation of the moving coil core is calibrated with respect to...
