In this HVAC Training Video, I show how to Quickly Test Gas Furnace Limit and Safety Switches such as The Flame Rollout Switch, Thermal Limit, Pressure Switch, and Flame Sensor. Safety Limit Switches can be Tested using a Multimeter and Measuring Electrical Resistance or Voltage! Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.
