International Comfort Products PHF060K000A Limit Switch
The reason limit switches exist is because if the warmed air is too cool then you will never get hot air through the ducts. The limit switch is a type of sensor switch in the heat exchanger that makes the determination when the heated air is warm enough for the main blower to kick in and circulate the air.
What red flags are there that my main limit switch needs replacing?
- Your system starts to stop suddenly more often than not
- System refuses to start nor will it stay running longer than 10 minutes
