Haier HPN10XHM Limit Switch
Limit switches are crucial because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heat exchanger that can determine when the heated air is warmed to a point that it can be circulated throughout the house.
What happens when my main limit switch has to be replaced?
- The Haier system begins to act differently more than once
- The heating and AC system refuses to kick in nor will it stay running even though the desired temperature has not been attained
