Nordyne 626434R Limit Switch This OEM replacement limit switch

This OEM replacement limit switch operates as a normally closed (NC) disc-style switch

This model is technically identical to the T834N1002/U SKU

If the high-limit switch fails or stays open

The metering performance remains consistent across both configurations

preventing accidental discharge and potential damage to the capacitor's dielectric material

Nordyne 626434R Limit Switch This OEM replacement limit switchThe Nordyne 626434R is a critical HVAC replacement part designed for pinpoint temperature regulation in furnace systems. As an OEM limit switch, this component is engineered to monitor high temperature operations, specifically featuring a 160 180F auto limit switch range. This furnace limit control operates on an "open on rise" switch action, meaning it breaks the circuit when the internal temperature hits 180? F (82? C) to prevent plenum overheating
