International Comfort Products H8MPV075F14B1 Limit Switch
The reason limit switches exist is because if the air never warms up then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heating area that decides if and when the air is warm enough so that it may be pushed through the ducts and out the vents.
Major symptoms of a laboring main limit switch
- The system begins to become inconsistent more often than not
- The heating and AC system refuses to kick in or run well longer than 30 seconds
