Oil Burner Primary Control and CAD Cell Operation and Troubleshooting!
In this HVAC Training Video, I show How the Oil Burner Works, How the Cadmium Sulfide Flame Detector (CAD Cell) Works, and How the Oil Primary Control (R8184 Protectorelay) Works. I go over the Electrical Troubleshooting with a Multimeter Reading Resistance Ohms and AC Voltage to Measure if the Components are Bad, Intermittently Working, or Functioning Properly.
