International Comfort Products PGAA36E1K1 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that makes the determination if and when the air is actually warm enough for the air to begin normal home circulation. Limit switches are crucial because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air.
Easy warnings of a dying limit switch
- The heating and cooling system is unable to start nor will it stay running like it is supposed to
