Limit Switches

Furnace limit switches are safety devices used to monitor temperature and protect HVAC equipment from overheating conditions. NWF Supply offers a selection of OEM replacement limit switches compatible with major HVAC manufacturers including Nordyne, Trane, and York.

These limit switches are designed to open or close electrical circuits based on temperature, helping to prevent excessive heat buildup and ensure safe furnace operation. All replacement limit switches are matched to original equipment specifications for temperature rating, electrical configuration, mounting style, and physical dimensions to ensure proper system protection and reliable performance.
