International Comfort Products VNE075F14G1 Limit Switch
The reason limit switches exist is because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. The limit switch contains a sensor in the air handler that determines if and when the air is actually warm enough so that it may be pushed through the ducts and out the vents.
General indicators that your critical limit switch is not going to last much longer
- System will not begin nor will it stay running like it ought to
- The International Comfort Products system starts to runs spotty more than once
