International Comfort Products GDE050B12A1 Limit Switch
One big reason why limit switches are designed that way is because if the warmed air is too cool then the house will never get warm enough. A normal limit switch has a sensor located in the furnace that can determine if and when the air is actually warm enough to activate the main blower.
Symptoms to watch for in a failing critical limit switch
- The HVAC system will not begin the ignition sequence or will not stay running even though max temp has not been reached
- The system begins to runs uneven time after time
