Desa R115 Limit Switch
The limit switch contains a sensor in the air handler that can determine if and when the air is warm enough that it can be circulated throughout the house. One big reason why limit switches are designed that way is because if the air never warms up the you will lose all the heat as the air flows through the ducts.
What are the clues to watch out for to know my chief limit switch is on its last leg?
- The heating and cooling system will not even start or will not stay running longer than a minute
- The HVAC system is starting to runs uneven more than once
