International Comfort Products PA9536AKA1 Limit Switch
A limit switch was crafted due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts. The limit switch is a type of sensor switch in the heating area that decides when the heated air is actually warm enough so that it may be pushed through the ducts and out the vents.
What red flags are there that my chief limit switch is on its last leg?
- System will not begin the ignition sequence or will not stay running even though max temp has not been reached
- Your system is beginning to stop suddenly from time to time
