Haier HPAC99ER Limit Switch
Limit switches were created because if the warmed air is too cool then you will never get hot air through the ducts. The limit switch contains a sensor located in the furnace that determines when the heated air is warm enough so that it may be pushed through the ducts and out the vents.
Cues of a defective critical limit switch
- The HVAC system is starting to act weird from time to time
- Your Haier system refuses to kick in or run for any length of time
