Description
The Tecumseh 8209660H39 is an OEM start relay (ST 9660C-041-166) engineered specifically for use with Tecumseh compressors. Start relays play a critical role in HVAC and refrigeration systems by energizing the compressor’s start winding during motor startup, then dropping out once the compressor reaches operating speed — ensuring smooth, reliable starts and protecting the motor from overload.
Product Overview
