International Comfort Products H8MPV075F14C1 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that can determine when the heated air is warm enough so that it may be pushed through the ducts and out the vents. This is important due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Elements of a failing main limit switch
- Your system is beginning to ramp up but then stops from time to time
- Your International Comfort Products system will not begin the ignition sequence or run for any length of time
