Whirlpool ATR0953BPP0 Limit Switch
Limit switches are built because if the air never warms up then you will never get hot air through the ducts. The limit switch is a switch located in the furnace that senses, or governs, when the air is warmed to a point to activate the main blower.
Subtle cues of an unhealthy limit switch
- The HVAC system will not begin or will not stay running for any significant length if time
- The HVAC system is starting to behave erratically on a regular basis
