The Tecumseh K71-09 Relay Kit is a compressor starting component designed to provide reliable electrical assistance during motor startup in HVAC and refrigeration systems. It works by temporarily engaging the compressor's start winding, delivering the additional torque needed for smooth and efficient startup before automatically disconnecting it once normal operation is achieved. Commonly used in Tecumseh compressors, air conditioning units, refrigeration equipment, and condensing systems, this relay kit enhances starting performance, reduces stress on electrical components, improves system reliability, minimizes startup failures, and helps extend the overall service life of the equipment
