i have a dual solenoid set up.  just recently it has starting acting up.  it will work for days and then all of the sudden i get nothing.  the motor is buzzing but it appears maybe the solenoids are not engaging.

my manual states both solenoids have to be working.  if just one is not then you're screwed.

my on the water work around is to lightly tap the motor with a screw driver.

my question is does this sound electrical? and if so what is more than likely the problem?

i looked into a new one OEM and they run a grand.  a rebuilt one is around 250, plus install.

i had a similar problem a few years back..the trim was getting louder and then stopped working, when i took things apart the wires on the brushes on the trim motor were just about toasted..to make  a long story short i ended up buying a new trim assembly  that came with a new wire harness and relays...maybe you could check the harness out somehow and just replace that..
