My Troybilt 31AH55R5711 Storm 3090 Electric Chute Directional Control is giving me some difficulty (serial number 11255B40226). This electric chute control is the 4-way toggle switch design (left/right, up/down). The chute will swing to the left and also will tilt up. The chute will not rotate to the right or downwards (although once in a while it will). Any advise on how to troubleshoot and resolve? Thanks much!
