Description
The Amana-Goodman 10728329 is an OEM replacement AUTO (automatic-reset) limit switch engineered to protect furnaces and heating systems from dangerous overheating conditions. Designed as a direct factory replacement for compatible Amana and Goodman furnace models, this limit switch monitors heat exchanger temperatures and automatically interrupts burner operation when temperatures exceed the rated threshold — then resets automatically once safe operating temperatures are restored.
Product Overview
Limit switches are a critical safety component in forced-air furnaces. When the heat exchanger reaches an unsafe temperature, the limit switch opens the control circuit, shutting down the burner to prevent equipment damage, heat exchanger failure, or fire hazard. The auto-reset design of the 10728329 means the switch will restore normal operation once temperatures return to the safe range, minimizing unnecessary service calls.
