International Comfort Products PYPA42GA1 Limit Switch
A limit switch was crafted because if the air never warms up then you will never get hot air through the ducts. The limit switch is a type of sensor switch in the heating area that can determine if and when the air is actually warm enough for the main blower to kick in and circulate the air.
What are some hints that my limit switch is about to stop working?
- Your system is starting to run erratically time after time
- Your International Comfort Products system will not start or will not stay running even though max temp has not been reached
