Why Is My RV Leveling Jacks Won’t Extend?

Leveling jacks offer a user-friendly approach to elevating your RV off the ground, facilitating routine maintenance tasks. Yet, the advantages of an automated system are accompanied by certain drawbacks. No jacking system for an RV is flawless.

Reason 01: Power Supply Issue

To ensure power supply problems affecting your Jacks, observe their response when activating the power button.

If the jacks remain entirely non-responsive, it indicates a power supply complication. However, if they only partially extend, an alternative problem with your jacks could be at play.

When something is a problem with your power supply, leveling jacks will decline to function. This precaution is in place to prevent mishaps, ensuring your RV remains secure during lifting attempts.

The last thing you must concern yourself with is your jacks malfunctioning during your maintenance session.

Solution:

Thankfully, rectifying power supply concerns with your jacking system is remarkably straightforward. 

Follow these instructions to effectively tackle these issues and ensure your automatic jacking system is operational for RV elevation during maintenance.

  1. Depressurize the air from your HWH system.
  2. Press and hold the auto-leveling button for 15 seconds.
  3. Allow a few minutes for the reset process to take place.
  4. After the system reboots, attempt to utilize the HWH jacking system again.

Restarting your jacks presents the simplest method to address power supply matters. The best part is that this resolution takes less than 10 minutes to complete.

Reason 02: Mechanical Malfunctions

Mechanical glitches are an inevitable part of any machinery’s lifecycle, and the system is not exempt from this phenomenon. 

Nevertheless, the method of resolving these mechanical errors can differ based on the specifics of your leveling system. Different models entail distinct requirements for addressing mechanical malfunctions.

Alternatively, if your jacking system displays these errors even before usage, it’s advisable to contact the manufacturer for guidance.

Between regular wear and tear and potential factory issues, mechanical complications are the most prevalent causes of the inability to extend jacks. Mechanical errors sporadically occur in any automated system across various industries.

A partial extension during usage or persistent retraction after extension might indicate a mechanical error within your HWH jacks. Unfortunately, the operation becomes infeasible when a mechanical error persists.

Solution:

Similar to the prior option, performing a system reset proves beneficial when encountering mechanical errors in your jacks. Executing a reset cycle is the optimal approach to mitigate extension errors attributed to power supply or mechanical malfunctions.

Reason 03: Connector Dysfunction

Loose connectors could potentially cause mechanical disruptions in your jacks. When the connectors within are not correctly secured, the efficiency of the power supply’s path can be compromised, resulting in the inability to extend the leveling jacks.

Interestingly, this is the sole troubleshooting approach on our list that doesn’t necessitate a system reset.

To determine the presence of loose connections in your HWH jacking system, the most straightforward approach is to inspect its interior.

Thoroughly examine each wire to ensure its correct attachment to the designated point and scrutinize these wires for any signs of damage. In the event of wire damage, establishing a secure connection to the power source becomes challenging.

Solution:

The corrective measures you undertake hinge on the specific problem at hand. For instance, reattaching the wires is imperative if they are disconnected from the power source. Conversely, damaged wires necessitate replacement.

To secure appropriate replacements, consider obtaining replacement wires from the HWH company to ensure compatibility. 

Alternatively, consult a professional mechanic for guidance on the precise wires your Jack requires. Avoid the mistake of acquiring incorrect wires for your device.
