## Description

Package Content: 1 x Starter Relays 4.7 ohm 3Pin + 1 x Refrigerator Overload Protector 1/2HP. Please note that this product is only compatible with QP-02-4.7 relay with 3 terminals. Not compatible with relays of other pin numbers. This kit is not suitable for all refrigerator compressors, only applicable to 110V compressors. 【Note】The maximum current that a 4.7 ohm relay can withstand is 12A. otherwise it will burn. ﻿ 【Note】Please carefully compare the pictures we provide with your old parts. Please check if your old relay is 3 pins. To make sure it fits your refrigerator. please consider before buying. 【 Installation 】Installation needs to be completed by professional maintenance technicians. Please make sure to unplug the power plug and wear work gloves before installation. Wiring during installation: Connect the terminals of the protector to the live wire, connect the second terminal of the PTC 3PIN relay to the neutral wire, and if there is a capacitor, connect the first and third terminals to the capacitor. When wiring, it is necessary to strictly follow the wires. Incorrect wiring can cause short circuits or damage to the equipment. The best solution to some common problems with refrigerators, such as compressor not starting, overheating, and a "click click" sound every 3-5 minutes after power on. There are many reasons that can cause the refrigerator compressor to not work, such as compressor noise failure, controller failure, wiring problems, lack of fluorine, etc. Before placing an order, you need to rule out other possible reasons that may cause the refrigerator to malfunction. ﻿

Review: Fits and fixed the problem - This is a standard relay which should fit many applications. I could not find my particular relay but after confirming the 3-pin pattern and getting past the fact that the capacitor looked completely different I took a chance. This fit completely differently but worked right away. FYI: my fridge symptoms: The compressor stopped running, but the relay would click once then again about ten seconds later. The compressor remained hot. This behavior is described as the relay coming on, not completing the circuit, then shutting off when it got too hot. I removed the existing relay and capacitor and shook it - if it rattles, that's your problem. The relay contact is broken/burned and can no longer complete the circuit. Popped the new one on, plugged it in, and compressor started right up.
Review: Fixed my kegerator - Worked like a charm in my Edgestar BR7001SS kegerator!

### ⭐⭐⭐⭐⭐ It worked!
*by C***N on May 13, 2025*

Purchased the day after my 3 year old apartment sized fridge went out. No longer getting cold in freezer or refrigerator. Googled and watched some You Tube videos and put the relay in myself. Saved me some time and money! Ladies you can do it too! Not very difficult!
