Haier HPN10XCM Limit Switch
The limit switch is a type of sensor switch in the air handler that determines if and when the air is warmed to a point for the air to begin normal home circulation. The reason limit switches exist is due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
What warnings are present when my limit switch most likely has to be replaced?
- The system is beginning to stop suddenly often
- The heating and AC system will not initiate nor will it stay running like it should
