Haier CPN12XC9-E Limit Switch
The main reason limit switches are made is because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a switch located in the furnace that determines when the heated air is actually warm enough to activate the main blower.
Simple indications of an unhealthy main limit switch
- The HVAC system is starting to runs uneven more often than not
- The heating and AC system will not begin the ignition sequence or will not stay running longer than a minute
