Hi,

We have an electric Yale lift that keeps shutting down the drive. It will drive fine in both forward and reverse for the first 10 or 15 minutes of use, but after that it will shut off the drive (with the lift moving under power--it makes a "click" sound and then the truck coasts to a stop). When it makes the "click", code -07 pops up and the maintenance icon lights up. For a few minutes, it is sometimes possible to put the truck in neutral, then back into drive, and keep going for a few seconds at a time. But that's getting desperate.

If we wait, say, 5 minutes, and then try again, it will go for a couple minutes, but then the process starts again.

All this points to some kind of overheating issue (to my uninformed mind). But I have no idea where or why, or what a code -07 means.

Any help would be much appreciated!
