Carrier 50HEQ003 Limit Switch
The limit switch has a sensor located in the furnace that determines when the air is warm enough so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
Important signs critical limit switch will not last the year
- System will not start or continue to run longer than 30 seconds
