Goodman ASPF426016 Limit Switch
Limit switches exist because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air. The limit switch is a type of sensor switch in the heating area that senses, or governs, if and when the air is actually warm enough for the blower to be activated.
Hints of a failing main limit switch
- The Goodman system starts to become inconsistent on more than one occasion
- The heating and cooling system refuses to kick in nor will it stay running longer than 30 seconds
