The 626470R Nordyne Limit Switch L155‑40F is a genuine OEM automatic‑reset temperature limit used in Nordyne, Miller, Intertherm, Maytag, Broan, Frigidaire, Gibson, and other Nortek‑built furnaces. Rated 155°F cut‑out / 40°F differential, this safety switch opens the circuit when the furnace cabinet or heat‑exchanger area reaches unsafe temperatures. Once temperatures drop back into the safe range, the switch automatically resets and restores operation.

This model is a direct replacement for 626470 and is commonly installed in mobile‑home furnace families. It prevents overheating, short‑cycling, and heat‑exchanger damage, ensuring safe and reliable furnace performance.
