How Reversing Valves Work

If you don’t know how it’s supposed to work, you’ll never truly know why it didn't. Reversing valves are definitely one of those "magic box" components until you actually see the pilot valve operating and how it works together with pressure differentials. Today, we’re tearing into the reversing valve. We recently ran into a unit that refused to shift, but the defrost board wasn't sending the signal. We’re going deep into the internal design to see how pressure differentials—not just electricity—make the magic happen. I’ve tried to trim the fat and keep the necessities so you can walk away with a better grip on how these fail and how to catch it faster on your next call.. #hvac #hvacapprentice #hvactechnician #hvaclife #hvacparts
