Whynter ARC-14S Limit Switch
The main reason limit switches are made is due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch has a sensor in the heating area that can determine when the air is warm enough that it can be circulated throughout the house.
Warnings critical limit switch needs to be replaced
- The heating and AC system will not even start or will not stay running as it should
- The HVAC system is beginning to behave differently frequently
