Paragon W18 Limit Switch
A normal limit switch is a type of sensor switch in the heating area that senses, or governs, if and when the air is warm enough for the air to begin normal home circulation. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
How do you know when your main limit switch needs replacing?
- The heating and AC system will not even start or continue to run longer than 10 minutes
- The whole system is starting to become inconsistent frequently
