I woke up this morning to find my miner doing nothing , and showing a red LED. I restarted and it mines , but it's getting fewer Gh. I looked at the cgminer config page and it looks like one of the units is out (match_work_count14 ). What could cause the red light and sudden stopping of one of the units?

The red led indicates a power supply problem.
I would guess the most likely problem to be a capacitor failed on the one miner section and shutdown the psu.
There's several pictures and reports of cap failures throughout the thread.

Hard to predict if it will shutdown the psu again or not but if it did I would consider removing the power connections on the bad miner section.

Thanks. That's what I figured. I looked at the modules to see if I could see a failed capacitor, but I was unable to find any noticeable signs of failure.

I assume that the numbers on the top correspond with the numbers of modules. So I figured the problem was at P14. I don't know how accurate that is. If that is the case, here's an album of that section. Maybe someone else can pick out an anomaly. I also took off that metal plate and looked to see if I could spot a burnt up ASIC chip.

EDIT: Also, sometimes [match_work_count14] => 0 will not be zero, implying that maybe it works sometimes. But the number is always magnitudes lower than the others.

Finally, it's been running for a couple days now on --avalon-auto without problem. So I haven't seen the red LED or any shutdowns.
