Cruiseair Solenoid Coil question

[Sailor John]

Good day all,
I have been trying to diagnose the non-functioning heat side of my Crusiair 16K AC. (The cold side works well). This is the AC unit that serves the main salon. It is not going into heat mode when the thermostat is turned to heat. No click, no whoosh, nothing. After some beneficial research through this web site, I was able (gratefully) to ascertain that my coil (that makes the solenoid work) may not be functioning. When powered up in heat mode, it does not cause the solenoid to move and there is no electric current creating a magnet in the coil. I traced and checked all the wires and everything seems to be fine.
My question is, does anyone know where I can get a replacement coil? I have attached a picture with the relevant details stamped on the coil bracket.
As always, I appreciate any suggestions.
Thank you all,
Sailor John
