Nordyne 626618 Limit Switch and 1F series low voltageThe Nordyne 626618 Limit Switch is a critical safety component engineered for HVAC furnace systems requiring precise thermal regulation. This OEM replacement part is designed to monitor heat exchanger temperatures, automatically opening the circuit at 175F and closing at 135F (L175 40). Acting as a high limit control, it prevents equipment damage and potential safety hazards by interrupting the ignition sequence if airflow is restricted or the system
