Haier CPN12XH9 Limit Switch
A normal limit switch contains a sensor in the air handler that makes the determination when the heated air is actually warm enough for the air to begin normal home circulation. The reason limit switches exist is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Major signs limit switch will not live much longer
- The system is beginning to behave differently repeatedly
- The HVAC system is unable to start nor will it stay running like it ought to
