2 Speed Fan Motor Board - Replaced with a 90340 Relay | Understanding HVAC Electrical Concepts

After continuing to being asked about switches on circuit boards and switches on a relay, I decided to replace another fan board with a 90340 relay. This time I chose to replace a 2 speed outdoor fan motor circuit board with a relay. Of course... I don't want you to think that this is the norm for any job. I am simply doing this to demonstrate that a switch is a switch and as long as you UNDERSTAND what you are doing you can easily master the concepts of a circuit board. I hope that this might show someone in the trade (not a homeowner) how relays haven't gone away. They are still there but incorporated into the circuit boards which have become so common in the equipment we use today. The circuit boards allow us to tweak the relays use to achieve better efficiency, etc. *please do not say that I told someone that you should do this, I recommend replacing OEM parts always.
