Troubleshooting the JD Skid Steer Door Closing Light and Starting Issues
#1
Introduction
A common issue faced by operators of the 2011 John Deere (JD) skid steer is the door closing light staying on, which leads to the machine not starting. This problem can be frustrating, as it prevents the skid steer from starting even when the door is securely closed. In this article, we’ll break down the potential causes of this issue and provide solutions to help get your JD skid steer back in operation.
Understanding the Problem
When the door closing light remains on despite the door being fully closed, it usually indicates a malfunction with the door switch or the associated electrical system. The machine is designed with a safety feature that prevents it from starting if the door isn’t properly secured, ensuring that operators are not exposed to unnecessary risks during operation. However, when the system fails, it can mistakenly interpret the door as open, preventing the engine from starting.
Common Causes
  1. Faulty Door Switch
    • The most common cause of this issue is a faulty door switch. This switch is responsible for detecting whether the door is open or closed. Over time, the switch can wear out, become dirty, or develop a short circuit, causing it to fail to properly signal the closed position.
  2. Wiring or Connection Problems
    • Another potential cause is a wiring issue. The wiring connected to the door switch may become loose, corroded, or damaged, preventing the switch from sending the correct signal to the skid steer’s electrical system. A loose connection may also intermittently cause the light to stay on.
  3. Faulty Door Latch
    • If the door latch isn’t engaging properly, it may not fully close the door, even if it appears to be. This can lead the system to believe that the door is open, keeping the warning light on. Dirt, debris, or wear and tear on the latch can prevent it from functioning correctly.
  4. Electrical System Malfunctions
    • The issue could also stem from a broader electrical system malfunction. In some cases, a blown fuse, damaged relay, or malfunctioning computer module can cause the door closing light to stay on and prevent the skid steer from starting.
Steps to Resolve the Issue
  1. Inspect the Door Switch
    • Start by inspecting the door switch. Locate the switch, which is typically near the door frame or latch. Check for any visible signs of damage, dirt, or wear. If the switch appears dirty, clean it with compressed air or contact cleaner to remove any debris. If the switch seems faulty or damaged, it may need to be replaced.
  2. Check the Wiring and Connections
    • Inspect the wiring connected to the door switch for any signs of damage, such as frayed wires or loose connections. Ensure that all connections are tight and free from corrosion. If you find any damaged wiring, repair or replace it as needed. It’s also a good idea to check the fuse related to the door switch system to ensure it is not blown.
  3. Examine the Door Latch
    • Check the door latch to ensure it is functioning properly. Ensure that it is clean, free from rust or debris, and that it securely locks into place. If the latch is worn or damaged, it may need to be repaired or replaced. Verify that the door is fully closed when the skid steer is powered off.
  4. Test the Electrical System
    • If the door switch and latch are in good condition and the wiring appears intact, test the electrical system. A malfunctioning fuse, relay, or module could be responsible for the issue. Consult the skid steer’s manual to locate the relevant fuses and relays, and check them for continuity. If you suspect an electrical issue, replacing the fuse or relay might solve the problem.
  5. Reset the System
    • In some cases, the system may need to be reset. Try disconnecting the skid steer’s battery for a few minutes, then reconnect it and attempt to start the machine again. This can help reset the electrical system and clear any false signals from the door switch.
Preventative Measures
To avoid similar issues in the future, consider the following preventative measures:
  1. Regular Maintenance
    • Regularly inspect and clean the door switch, latch, and wiring to ensure they are in good working order. Periodic maintenance can help prevent dirt buildup and wear that may cause the system to fail.
  2. Avoid Overloading the Door
    • Be mindful of the door’s operation. Avoid slamming the door or forcing it closed, as this can damage the switch or latch over time.
  3. Electrical System Checks
    • Periodically check the electrical system for any signs of wear or damage. Keeping the electrical components in good condition can prevent unexpected failures.
Conclusion
The issue of the door closing light staying on and preventing your 2011 John Deere skid steer from starting is a relatively common problem that can typically be traced back to a faulty door switch, wiring problems, or a malfunctioning door latch. By following the troubleshooting steps outlined above, you can resolve the issue and get your skid steer back to work. Regular maintenance and attention to the electrical system will also help prevent similar issues from arising in the future.
