Colonists not repairing deep refrigerator

[richardmv]

A while back one of my deep refrigerators broke down and is in need of repair. I have a decent component stockpile but none of my colonists will fix it. When I right click on the deep freezer, it stays there are not enough components, even if the colonist I have selected has three (the number required to build the object) in his inventory. This issue has persisted for a few play sessions now, so it doesn't seem like something that will just resolve itself, as can sometimes happen with RimWorld.
