Friedrich MW24Y3F Limit Switch
A limit switch was crafted because if the air never warms up 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 heated air is warm enough for the main blower to kick in and circulate the air.
Major signs limit type switch will need to be replaced
- The heating and AC system will not start nor will it stay running longer than 10 minutes
- The Friedrich system is starting to runs uneven more than once
