I think it is important to add that reversing valves require two things in order to switch its flow - A properly functioning coil and the proper difference of pressure from low to high pressure. Therefore a properly functioning compressor and the correct freon charge is required to properly diagnose a reversing valve. A reversing valve that is not fully switching can be a compressor killer because it can add high pressure/temperature gas right into the suction of the compressor.

I think you need to be FAR more specific in the temperature difference between the
There should be one of the group of 3 pipes that is within 5° of the single pipe and the other 2 pipes of the group of 3 should be within 5° of each other.

Example using top and bottom based on how the valve sits in the video:
Top pipe is 75°
Slide is to the right.
Left bottom pipe is 70° - 80°.
Middle pipe and right pipe should be 45°, +/- 5°.
Temperatures are for reference and NOT actual temperature you are looking for.

Lol subscribe d , editing in The noise of the canue had me laughing. Pretty sure only us guys in the field know that sound 😅

How is easiest way to access when condenser fan is running?

How do you test a reversing valve with bad compressor valves?

[marconantel]

Are they fairly universal? How do you tell one that is o vs b energized?

Why do reversing valves go bad/leak so much.
