Frigidaire FRS123LW11 Limit Switch
Limit switches are built due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts. The limit switch is a switch located in the furnace that can determine when the air is warmed to a point for the main blower to kick in and circulate the air.
Indications limit switch will not last the year
- The Frigidaire system is starting to behave differently often
- The heating and AC system will not begin or run well even though max temp has not been reached
