International Comfort Products N8MPN075B12B1 Limit Switch
The main reason limit switches are made is 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 switch in the air handler that determines if and when the air is warm enough that it can be circulated throughout the house.
Key indicators that my limit switch has a need to be replaced?
- The HVAC system is unable to start nor will it stay running longer that five minutes
- The HVAC system starts to behave differently occasionally
