Cooling fan spins 1/2inch at a time causing it to run hot
Welcome to HEF Gunter . You have a machine serial # ? Do you know if it has the reversing fan option? Any story with the issue, just started …or got worse over time ? If the fan is barely turning, there may be an air lock in the fan drive hydraulic system. You could remove the solenoid valve to bleed off any air.
If you have an early SR# 160DLC check your suction hose from fan drive pump to reservoir for clamps and tighten all clamps. The inferior hose and clamps would allow air to enter suction side of fan drive pump. Most of those early units should have had an update kit installed but some may have been missed the update kit had no hose clamps at the connections
I got it figured out it was the pump on the motor
