Troubleshooting the Fan Limit Control Switch on a Furnace, Temperature Settings, How it Works!

In this HVACR Troubleshooting Video, I go over how the Fan Limit Control Switch Works on a Gas or Oil Furnace, What temperature to set the 3 Temp Adjustments to, How to identify a problem, and I go over Resistance Reading Checks on the Fan and Limit sides of the control. This Honeywell Combination Control is common on most older gas and oil-fired furnaces. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.
