Coleman DGAA056BDTA Limit Switch
The limit switch has a sensor in the heating area that can determine when the air is actually warm enough that it can be circulated throughout the house. The main reason limit switches are made is because if the air is not warm enough then you will never get hot air through the ducts.
Indications of a barely functioning critical limit switch
- The heating and cooling system will not initiate or run well for any length of time
- The whole system starts to become unpredictable often
