Hi Steve,
If the coil is not shorted, repair may be an option. When mine clogged up I was able to make some mods ( can't remember the details ) to get it going again.
In addition to what Forrest says, it serves as an unloader for the compressor. It is a normally open valve. So when compressor is running the 120vac applied to the compressor is also applied to ta relay which in turn applies 12vdc to the solenoid. That closes the valve, trapping the air and water. When the compressor stops, the solenoid is de-energized, the valve opens, the water and air drain out and the compressor is able to start unloaded when the next cycle rolls around.
