A Broken Bed?

Do you have a power bed lift in your Newmar Dutch Star? Did it suddenly stop working? Did you call Newmar and then spend the next several hours trying to make the darn thing work only to find out that it was something very basic and very simple?

I hope this post helps you out if your power bed lift has stopped working.

We usually keep our king bed in an upright position during the day as it provides a bit more space in the bedroom. At night, we lower the lift to flatten the bed. It makes things a bit easier for sleeping.

Except two nights back the bed would not flatten. It remain locked in the upright position.

I spent the next several hours trying to get the bed to flatten. It was so frustrating. There is no documentation anywhere that I could find on how the power bed lift is wired and how it operates. No manual. No troubleshooting guide. Nothing.

I even came up empty on the usual social media sources. Perhaps we were the only ones to run into a power bed lift that stubbornly refused to flatten.

It appears as though there is no easy way to manually override the mechanism. It was locked and it was not going to move. Newmar support confirmed that wonderful feature with me the following day.

My first course of action was to check for a bad fuse. That proved to be an interesting exercise.

I do have all of the fuse panel schematics for our coach including the breakdown of most of the fuses in our bus. Newmar likes to keep its customers on their toes. There are all sorts of hidden fuses scattered about the motorcoach.

There are five fuse panels and each one contains dozens of fuses. Here is one of the schematics to give you a sense of the underlying complexity of the 12V system in the coach.

I keep a substantial number of spare 12V fuses on hand along with a fuse checker and a multimeter. I checked each and every one of the panels and I could not find anything labelled “Bed Power Lift” or similar.

I found out why there was no fuse for the power lift on any of my charts.

It is a hidden fuse. It is an undocumented fuse.

I did not find that out until after my call with Newmar.

It is a glass fuse nicely hidden by the awning motor control modules in our basement bay. You can just make it out under that little black box with the two white wires.

Dead end for me. Even if I had known about that fuse when I first began my troubleshooting it would not have made any difference. The fuse tested fine.

Newmar had no idea what to do about the problem. Perhaps it was a bad motor? They told me that they would do some digging to see if there was a way to flatten the bed without power and that they would get back to me.

They did call me back. And they told me that they had no idea how to resolve our issue. However, at that point in time, I had fixed the issue.

I had decided to get inside the bed casing where the motor and gearbox are situated to take a closer look and to check on the wiring connectors to the two power bed lift switches.

We had spoken with our service manager at our dealership and he had suggested that I check for any loose connections under the bed. It turns out that his hunch was bang on — thank you Paul! — but trying to get into that area was very difficult.

It took me the better part of an hour to get under the bed assembly and to check on the wiring. There were at least half a dozen connectors down there and one of them was loose.

More than loose. The black wire had become detached from the white wire in the cable pair probably due to the movement of the power bed lift.

It wasn’t easy to get in there to crimp the wire, re-twist the pair, and reinsert the connector cap. But once that was done, the power bed lift worked.

This short video walks you through the process of the repair.

Funny how six or seven hours of time can be condensed into a minute or so. I reported my findings back to Newmar support and perhaps they will be able to provide others with a bit more help in terms of potential troubleshooting for this issue.

A real design flaw. There is no way to defeat the power bed lift short of full disassembly. Thank heavens I didn’t go down that path.

We now have a flat bed.

I did not have to sleep on the floor last night.
