Carrier 24ANA736A0030020 Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that makes the determination if and when the air is warmed to a point to activate the main blower. A limit switch was crafted because if the warmed air is too cool then the house will never get warm enough.
What are some hints that my critical limit switch is about to stop working?
- The HVAC system is beginning to shut down unexpectedly from time to time
- The HVAC system will not begin or run well longer than 10 minutes
