That is a beautiful looking reversing valve, simply beautimus. I know how a reversing valve works
On a reversing valve selonoid, window unit AC heatpump, if there is voltage, 120 at the reversing valve, does that normally mean that the selonoid is bad if the unit is blowing cold air in heating mode. Or can the switch, reversing valve or thermostat be stuck.
O.K. Apparently no one on this forum can answer a simple question. Well, I'll find the answer, but I guess it won't be here. So sorry! Apparently you don't understand the question anymore than I do! And I am new at it. I am starting to find out there is no true answer to any of it, and one tech or another it doesn't matter, and there is no real answer, because there are no real technicians, anyhow the term for technician is "Someone who is skilled in the field they work in" But there are no experts on any subject." Oh well, you gave it half a shot!
