Carrier 38CKC024 Limit Switch
Limit switches were created because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch contains a sensor in the air handler that senses, or governs, if and when the air is warm enough for the air to begin normal home circulation.
Hints of a dying limit switch
- The whole system starts to behave differently more than once
- The HVAC system will not even start or will not stay running longer than 30 seconds
