this industrial HVAC compressor part provides the precise fit and material integrity required for long-term system reliability and peak operational performance

using this specific P321826 vent switch ensures exact physical fitment and proper operation of the safety loop without the risk of nuisance tripping or delayed response times associated with generic universal alternatives

As the direct superseded part for the 632323 ignitor

is designed to capture microscopic contaminants that can compromise compressor bearing surfaces and affect the thermal conductivity of the refrigeration cycle

Field Controls 1170004 Switch 340155-7024 this industrial HVAC compressor partThe Field Controls 1170004 (FTS 4) is a critical manual reset thermal safety switch designed to protect gas fired furnaces, boilers, and water heaters from hazardous flue gas spillage. This SPST thermal switch monitors temperatures at the draft hood or barometric control, effectively de energizing the burner circuit if hot gases escape due to a blocked flue or inadequate chimney draft. Engineered for heavy duty applications, it features a 140F fixed
