Payne PY2PNB060115AA Limit Switch
A normal limit switch is a type of sensor switch in the heating area that senses, or governs, when the air is actually warm enough that it can be circulated throughout the house. A limit switch was crafted because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Important hints limit switch should be replaced
- The heating and AC system is unable to start or continue to run longer than a minute
- Your system starts to run inconsistently frequently
