Description
The S1 7995 3281/A is a factory spec auto limit switch from York, intended to serve as a safety cutoff/thermostat for furnaces or HVAC systems. It helps protect the system from overheating or unsafe operating conditions by interrupting function when internal temperatures exceed safe thresholds, then restoring normal operation when temperatures fall back.
Key Features
- Auto Reset Limit Switch (120 °F close / 150 °F open) — Automatically interrupts operation when internal temperature reaches 150 °F; resets when temperature drops to ~120 °F.
- OEM Grade Safety Component — Genuine York part built to original equipment specifications — reliable fit and function for units designed to use this switch.
- Compact & Lightweight Design — Small form factor makes it easy to install or replace in furnaces or HVAC control panels without significant modification.
- Critical Overheat & Fan Control Protection — Monitors internal air or combustion temperatures; if overheating occurs or fan fails, it prevents unsafe operation by shutting down the system.
- Broad Compatibility with York / Coleman / Furnaces — Used in many furnaces and HVAC units (e.g. models listed under “7995” series), making it a common replacement part when the original limit switch fails.
- Simple Replacement/Retrofit Option — Ideal for maintenance, repair, or replacement of outdated or malfunctioning limit switches — helps restore safety and proper operation without major upgrades.
