Our new refrigerator suddenly began to alarm (the freezer side is fine.) We get a "door" code where the temperature used to be . We checked all doors and they are fine.

sounds like the rods are disconnected the clips hold the rods in place the latching mechanism holds the handle in place as well did you replace the speakers or did a shop? if a shop did then they caused this if you did then you may have caused this either way untill you reattach the rods none of it will work. you will have to manually open the door at the latch from inside teh door behind the panel.

This is only a possible solution to your problem. I had similar problem with my car. It turned out that the window locking toggle on the driver door not only prevented the other windows from being opened by passengers but also controlled the door locks. When I unlocked the window control I was able to unlock the door. Another possibility is the armature inside the door has come off the locking mechanism.

I had a similar problem with my son's 1998 Jetta K2 4 door. I sprayed loads of WD40 into the locking area from the end of the door through the clip slot, worked the mechanism sprayed some more and finally it start working. My mechanic said these are very prone to moisture causing rusting on the moving parts.

you might also have to drill out the rivets that hold the lock actuator on to be able to manage the last roller into the scissor assembly. Use larg 1/2 in sheet metal screws to reattach.

SOURCE: 02 VW Jetta locks, remote, lights, windows stopped working

Same problem with an '03 Golf--remote entry, power windows, and interior lights stopped working. This was easily fixed by replacing fuse #14, (10 amp), located in the driver's side fuse block.
