International Comfort Products C8MPV075F14B1 Limit Switch
A normal limit switch has a sensor in the heat exchanger that decides when the heated air is actually warm enough to activate the main blower. Limit switches are built because if the warmed air is too cool then you will never get hot air through the ducts.
What are some indications that my critical limit switch is in need of a replacement?
- The system is beginning to behave differently more than once
- The heating and AC system will not begin the ignition sequence or run well as it should
