International Comfort Products EF20N2600A2 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that makes the determination when the air is warmed to a point so that it may be pushed through the ducts and out the vents. Limit switches exist because if the air never warms up then the house will never get warm enough.
Some clues of a faulty limit switch
- The heating and cooling system will not start nor will it stay running like it should
- The International Comfort Products system begins to ramp up but then stops time after time
