International Comfort Products T8MPT125J20A1 Limit Switch
Limit switches were created 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 contains a sensor in the heat exchanger that senses, or governs, if and when the air is actually warm enough for the blower to be activated.
Hints limit switch has very little life left
- The heating and cooling system will not begin the ignition sequence or run for any length of time
- Your system begins to become inconsistent occasionally
