Thank you! Great vid. I've removed reversing valves in package units but never residential style like this with coil directly behind it. I'm assuming you use a heat shield to prevent damaging the coil?
That's a good tip, because the tuning fork torch tip is hard to use. So I do something similar when replacing the liquid headers on the Carrier RTU with the individual metering devices on each coil tube that always plug up. You cant heat 4 or 5 tubes up all at the same time so I snip them off and then un sweat them individually. Typically in Chicago on commercial units when the reversing valve starts to stick people opt to just remove them pipe them straight and make it a conventional unit at that point and use the electric heater. Mostly see them by the lake, further in land they use retention ponds instead of air to air.
You can only check the coil for short to ground or to see if coil open, a good test is to energize and de energize the coil while the compressor is running to check valve switching
Why is the blue wire off the spade connector on the valve? Was that an accident and came off? I’m in Chicago Always wanted to work on them but not much here. If possibly do a video on thermostat wire connection.
the connector was off because this heat pump is designed to fail safe in heat mode hence if the valve isn't powered it's in heat mode, and because the outdoor fan fan cycling switch or low ambient control isn't functioning when the system goes into defrost mode this causes head pressures to be extremely low, so low there isn't enough differential pressure so the valve can switch back to heat. This was a temporary fix to keep the heat going
Thanks for that knowledge .
Thanks for watching
Great tip tech
Thanks

Yes! however ONLY when installing the new valve i use wet rag or wet rag paste,,... for the removal process this isn't needed!

Sweet thanks for watching
Great video! I just wanted to ask, how can I check if a 4-way valve is healthy or not using a multimeter? I would really appreciate an explanation.

What wireless gauges are those?
Parker smart service tool kit
Another UA-camr says he uses bolt cutters, but I don't know all the details.
if you can fit them into the gaps between pipes 🤷♂️
