Carrier 38BYC030 Limit Switch
The limit switch is a type of sensor switch located in the furnace that decides when the heated air is warm enough for the main blower to kick in and circulate the air. This is important due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Major clues of a worsening main limit switch
- The HVAC system refuses to start or will not stay running longer than 10 minutes
- The whole system is beginning to initiate and then stops from time to time
