International Comfort Products NDC7100BHA3 Limit Switch
A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a type of sensor switch in the heating area that senses, or governs, when the heated air is actually warm enough so that it may be pushed through the ducts and out the vents.
Subtle hints main limit switch will have to be replaced
- Your International Comfort Products system refuses to start nor will it stay running longer than 10 minutes
- The HVAC system is starting to ramp up but then stops occasionally
