Having an intermittent problem with the elevator running in the up direction on full speed. Coils on the valve checked out good, (4 coils) . K1 relay ringed out good, even get the high speed light on the DRV board but it still runs up like it was on access. I refered to print 800767E04. Any one had this ? Only in the up direction, 2 stops and happens intermittent .
