International Comfort Products NTC7125BKG1 Limit Switch
Limit switches are crucial due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. A normal limit switch has a sensor in the heat exchanger that senses, or governs, if and when the air is warm enough to activate the main blower.
How can I tell if my critical limit switch is almost going bad?
- The heating and AC system will not initiate nor will it stay running longer than 30 seconds
- The whole system is starting to erratically often
