Fisher HT - Plow won't raise
New to this forum, first post.
My Fisher HT, purchased with a new 2011 Silverado and dealer installed, has worked flawlessly for 8 years. Recently when plowing a wet and rainy storm the blade wouldn't come up. I can't recall if it would angle left or right either - I should have made note of this but didn't. No sound at the motor, controller didn't seem to do anything. I may be imagining this, but I thought I heard a "beep" at the controller that I've never heard before. I didn't check if there was a flashing light at the controller at the time (didn't know any better). It happened intermittently at first, then more frequently, so I gave up, not wanting to be left with the plow in the down position to drive home. Was working fine when I put it away (ie. intermittent)
What's the possibilites - replace main solenoid? the lift solenoid? Solenoids overheating? Just check the connections (I use dialectric grease). Could it have been a grounding issue with the rainy, somewhat warm weather or other related issue?
