This universal solid - state start relay is a great fit for most hermetic compressors ranging from 1/2HP to 3HP. It comes with part numbers RF617, QP2 - 37.5 - 148, and L701, though now Supco SPP is recommended. This electronic relay can replace the start relay in many large refrigerator compressors and most air conditioner compressors. The original motor overload should still be used. It's suitable for 220 - 240VAC hermetic compressors from 1/2HP to 3HP (375W to 2240W), and it helps prevent start winding overheating. It has standard 6.4mm female spade terminals and can be installed in seconds. With over 25 years of experience supplying appliance parts to both trade and retail, you can buy with confidence.
Using this start relay is easy. First, make sure your compressor is within the 1/2HP - 3HP range and uses 220 - 240VAC power. Keep the original motor overload in place as it's still needed. Connect the relay using the standard 6.4mm female spade terminals. It should only take a few seconds to install. When it comes to maintenance, there's not much to do, but keep an eye on the compressor's performance. If you notice any issues like overheating, check the connection of the relay. Always make sure to turn off the power before handling the relay to avoid electrical shock.
