Carrier 38YZA036 Limit Switch
Limit switches are crucial because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. The limit switch is a switch in the heating area that can determine when the air is actually warm enough for the blower to be activated.
General warnings of a bad main limit switch
- The Carrier system begins to go through the startup sequence but stops quickly on more than one occasion
- The heating and AC system refuses to start nor will it stay running for any length of time
