International Comfort Products NDP6050FBB1 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 contains a sensor in the heating area that can determine when the air is actually warm enough for the main blower to kick in and circulate the air.
Simple indications of a failing limit switch
- The whole system is beginning to behave erratically on a regular basis
- System will not begin or will not stay running like it ought to
