Failed bed chausson titanium

[smudge100]

I have a chausson titanium 7 2020 - not new to motorhoming or camping but first time with electric bed in front. It’s failed and I had to manually wind it! I see the fuse box outside but nothing obvious is there a fuse box elsewhere or something else I can. Try? Please

I don't know if this helps at all.

When an electric bed (drop-down or elevating bed) fails in a motorhome, it is commonly due to power loss, mechanical obstruction, or motor/switch failure.
Here is a guide to troubleshooting and fixing electric bed failures in motorhomes:

1. Immediate Troubleshooting Steps

• Check Leisure Battery Voltage: Electric beds require significant power. If your leisure battery is below 12.6V, the motor may not have enough power to lift the bed, especially if it is fully made up with bedding.
• Ensure Proper Power Source: Ensure you are hooked up to main power (EHU) or that the engine is running (depending on the manufacturer's design, some beds only work with 12V while others require higher, stable power).
• Check Fuses: Locate the fuse box and check for blown fuses, particularly those labeled "bed," "lift," or "auxiliary".
• Check for Mechanical Obstruction: Ensure no pillows, blankets, or items are stuck in the mechanism. The weight of a fully made-up bed can sometimes exceed the motor's limit (often around 60kg).

2. Common Causes of Failure

• Broken/Loose Wiring: The wires for the bed motor can come loose due to road vibrations. Check the connections at the motor itself.
• Failed Limit Switch: Electric beds use limit switches to know when to stop at the top and bottom. If these fail, the motor will not start.
• Loose Guide Rails or Rack: The runners, guide wheels, or rack mechanism may need adjustment or lubrication.
• Faulty Switch: The wall switch or remote control may have failed.
• Motor Failure: The motor may have failed due to overloading or age.

3. How to Manually Lower/Raise the Bed
If the motor is completely dead, most electric beds have a manual override mechanism.

• Locate the Motor: Access the motor (often hidden behind panels in overhead lockers).
• Use the Emergency Key: Most systems allow you to use a hex key (Allen key) or a special emergency handle to wind the bed up or down manually.

4. Technical Checks

• Test for 12V at the Switch: Use a multimeter to see if power is reaching the operating switch.
• Check the Motor Reset: Some motor units have a small reset button directly on them.
• Inspect Earth Connection: A bad earth connection to the chassis can cause intermittent failure.

If the bed still fails after these checks, it may require a professional repair, particularly if the motor needs replacing.

Hello.

I have 22 plate 720, had same problem. Found there was a fault with the board and no power getting to the fuse, see attached photo of fix.

Not sure if OP is trapped between bed and ceiling?
