Over our life time, wire does not degrade. Exception being if it is in a excessively corrosive environment, which would also eat away the machine before the wire. Wire is however subject to mechanical damage, even if you cannot see it.
Degradation in current carrying capacity in circuits is almost ALWAYS related to bad connections.
The transition from the wire to the connector is the most common point of failure. Vibration, and movement causes fatigue in the wire, the strands break. Slowly over time, there it not enough functioning conductor to pass enough current.
I am betting on this. When you changed solenoids, you moved the wires. Just by chance the conductors moved back into contact and the new solenoid worked until the wires vibrated apart again.
I have made this repair hundreds of times over my 50+ years of working on things. I cannot count how many times I have had to shorten the cords on hair dryers for my wife and daughter. They wrap the cord around the dryer, toss it in a drawer. 365 times a year that cord gets wrapped around, bending the wire in the exact same spot, the wires break.
It can happen anyplace the wire is stressed. I have NEVER seen wire break in the middle of a run, UNLESS it makes a sharp bend and it subject to flexing. CHECK all of your wire ends. Often the insulation looks good but the conductors are broken inside. Sometimes you can see heat damage as heat is generated as current flows through the areas of resistance.

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
