Lennox 27H87 Auto Limit Switch 120°F-160°F

The Lennox 27H87 Auto Limit Switch is an essential safety component manufactured and intended for use in Lennox furnaces. This automatic switch is an unseen protector of your comfort system to avoid high temperatures and subsequent harm to the system. Intended to operate in a certain temperature range of 120°F-160°F, the switch shuts down the power supply to the furnace if it gets too hot. This avoids overheating which may destroy your equipment and might even be a danger to the users. Through preventing overheating, the limit switch plays a major part in maintaining the general reliability and longevity of your Lennox furnace.
