International Comfort Products PH5542AKA1 Limit Switch
A normal limit switch is a switch in the air handler that senses, or governs, when the air is warm enough for the main blower to kick in and circulate the air. Limit switches are crucial because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Hints of a barely functioning limit switch
- System will not begin the ignition sequence or continue to run longer than a minute
- The International Comfort Products system starts to run inconsistently time after time
