Carrier 25HPA442A0030010 Limit Switch
A limit switch was crafted due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch is a type of sensor switch in the heat exchanger that determines when the air is warm enough for the main blower to kick in and circulate the air.
Signs of a worsening limit switch
- Your Carrier system will not begin the ignition sequence or run well for any significant length if time
- The system starts to behave differently often
