The solenoids are the culprit. They are shorting out. The solenoids are NOT continous duty solenoids. IF they stay on longer than 10 to 15 minutes, they overheat and short out internally. The fact that the other solenoids get hot point to that at some time the system was left ON in retract for more than 15 minutes. That will happen when one or more jacks do NOT fully retract and the system will stay on until the jack is retracted or you shut the system off. You really need to replace all 4 solenoids. The ones that get hot but function will fail in the future. THAT is why the fuse blows---it PROTECTS the Main control board system. Doug
