Precise 150F Cut-Out: Calibrated specifically for high-limit protection to prevent heat exchanger damage or unsafe operating conditions

Amana-Goodman 10728329 Limit Switch Check your specific Maxitrol springThe Amana Goodman 10728329 Limit Switch is a critical safety component designed for precise thermal regulation within the furnace plenum. This OEM furnace limit switch operates on a calibrated 110 130F temperature range, functioning as a primary high limit safety to prevent heat exchanger fatigue and potential cracking. When the furnace high limit sensor detects temperatures exceeding the 130F threshold, it interrupts the burner circuit while allowing
