Tecumseh K90-20 Overload 318172-701 This "I" style port andThe Tecumseh K90 20 Overload is a critical compressor protection component designed to safeguard HVACR refrigeration systems against excessive current draw and high temperature conditions. Engineering for Tecumseh hermetic compressors, this thermal overload switch utilizes a precise bimetallic disc to interrupt the electrical circuit when internal temperatures or amperage exceed safe operating limits. This prevents motor winding failure and ensures
