Haier CPRB07XC7-E Limit Switch
A normal limit switch is a type of sensor switch in the heating area that determines if and when the air is warm enough that it can be circulated throughout the house. The main reason limit switches are made is because if the warmed air is too cool then you will never get hot air through the ducts.
Major indications limit switch is dying
- The heating and cooling system will not even start or run like it should
- The system starts to behave erratically more often than not
