Amana-Goodman 10728329 Limit Switch

110-130F AUTO Limit Switch. For those seeking quality assurance and durability, the Amana-Goodman 10728329 Limit Switch works as a high-quality OEM replacement unit. This auto limit switch ensures the temperature of the air around the heat exchanger should not become too hot, and hence shuts the burner off in such situations to prevent a potential crack of the heat exchanger. In case your furnace's blower continues to operate without shutting off, you might be in need for a replacement of your limit switch.
