Payne PH2PNB060000AA 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 senses, or governs, if and when the air is actually warm enough that it can be circulated throughout the house.
How do you know if your critical limit switch is almost dead?
- The HVAC system begins to runs spotty from time to time
- Your Payne system will not begin the ignition sequence or run well even though the desired temperature has not been attained
