Why Trane Xr90 Limit Switch is Necessary?

As a homeowner, I have learned the importance of having a reliable and efficient heating system. One crucial component of my Trane Xr90 furnace that ensures its safe and optimal operation is the limit switch. This small yet essential device serves as a safety feature that prevents the furnace from overheating and causing potential damage or hazards.

First and foremost, the Trane Xr90 limit switch acts as a temperature control mechanism. It continuously monitors the temperature inside the furnace and shuts off the burner if it reaches a predetermined limit. This prevents the furnace from exceeding its maximum operating temperature, which could result in system failure or even fire.

Moreover, the limit switch also plays a significant role in maintaining proper airflow within the furnace. If there is an obstruction or blockage in the system, such as clogged filters or vents, it can cause a buildup of heat that could trip the limit switch. This feature helps to prevent any potential damage to the furnace due to restricted airflow.

In addition to protecting the furnace itself, having a functioning limit switch also ensures my family’s safety. Without this safety feature, there is a risk of carbon monoxide buildup in our home if the furnace were to overheat
