OEM vs. Generic

This factory-original switch is calibrated to the exact trip temperature the furnace control board expects. Generic switches cost less but often have looser tolerances that cause nuisance trips or fail to protect at the correct threshold. For a safety-critical part, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). Two spade terminals and typically two mounting screws. Always disconnect power at the breaker first. If the furnace short-cycles on limit, check airflow (dirty filter, blocked coil) before replacing the switch.
