Frigidaire FRS18PYW20 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that senses, or governs, when the heated air is warm enough so that it may be pushed through the ducts and out the vents. Limit switches exist because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Easy warnings of a defective limit switch
- System refuses to start or run well longer than 10 minutes
- Your system starts to become unpredictable on more than one occasion
