International Comfort Products N8MPL100F20A1 Limit Switch
A limit switch was crafted due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch has a sensor in the air handler that decides when the heated air is warmed to a point for the main blower to kick in and circulate the air.
How do you know if your critical limit switch needs replacing?
- The heating and AC system will not even start or run well longer than 30 seconds
- The system starts to act weird repeatedly
