Bryant 330AAV Limit Switch
A normal limit switch contains a sensor in the air handler that can determine when the air is actually warm enough that it can be circulated throughout the house. This is important because if the warmed air is too cool then you will never get hot air through the ducts.
Simple warnings that your limit type switch really is in need of a replacement?
- System will not even start nor will it stay running like it should
- The whole system begins to run erratically often
