International Comfort Products GPFM42K100F Limit Switch
Limit switches were created 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 has a sensor in the heating area that determines when the heated air is warm enough for the main blower to kick in and circulate the air.
Subtle hints main limit switch should need replacing
- The heating and cooling system will not begin or continue to run for any significant length if time
- The whole system is beginning to run inconsistently more often than not
