My drop down bed comes down ok but will not go up. Fuses are ok. Any suggestions please.

Welcome to the forum Trevor, I assume the bed is in a Motorhome. Is the mechanism electric over hydraulic or is it raised on cables?

Might be linear actuators?
The OP needs to give us more info,
Cheers,
Peter

Thanks for the replies so far. It is in an Avan Ovation motorhome. It is electric

I am a bit of a novice. Where is the uplimit switch and what is a linear actuator

We need to know about how the mechanism works.
If it won't go up, how do you know that it still goes down?
Post some pics of the mechanism.
Cheers,
Peter

It is a HappiJac brand bed lift. When I am not using my motorhome the bed is always in the up position. On this occasion the bed came down ok but would not go back up

Start pulling things apart, sometimes faults are obvious when you can see the mechanisms, Can you hear a motor sound when it's coming down? Is there any indication or sound when you try to raise it? Is it a 2 way switch that raises & lowers it? If there is a motor noise coming down tells you the motor should be o.k., if the motor runs trying to raise it you have a mechanical problem, maybe broken cables.

Great video in that it perfectly explains functions and possible areas of malfunction.
