International Comfort Products NTC6075FBG1 Limit Switch
Limit switches were created because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts. A normal limit switch is a switch in the air handler that can determine when the air is actually warm enough for the main blower to kick in and circulate the air.
Simple warnings that your main limit switch is almost going bad?
- The heating and cooling system refuses to start or will not stay running longer than a minute
- The whole system begins to go through the startup sequence but stops quickly frequently
