In this HVAC Troubleshooting Video I show you how the Fan Control works in Boilers, Furnaces, and Air Conditioning units for Troubleshooting why the Blower Motor is not Working and during the Heat or A/C cycle. I show you the voltage flow from the door switch through the fan limit and to the fan control which includes the general-purpose relay and back out to power the blower motor. I also show you the fan limit control and how it powers the fan during heat mode and where the fan limit is connected and how to read the voltage across it. I show you step by step what to check for until you get voltage through the controls and to the blower motor. Supervision is needed by a licensed HVAC Tech before doing this as Experience and Apprenticeship garners Wisdom and Safety.
