Are you saying that the expansion box is working ok for all relays?

Yes, under the test code one relay box is perfect, the other has port 4 stuck on. I have a third box, the original one I purchased, which has I believe two bad ports. Can I disassemble that one and make one working box from the parts?

Yes, you can pop it open to scavenge the relay.
What did you have connected on that port?
You mentioned they were working before you put all together with a night lamp.
And this still doesn't explain how the expansion box works with the test code and not with your code... :?

Right, that I tested everything with a lamp previously is troubling. I may have missed that port somehow though. The bad port has always had two korellia powerheads plugged into it. My understanding is that heavy loads, if anything, would be a problem, such as a bunch of metal halide ballasts. In this instance, however, it has either been a small incandescent lamp or two powerheads.

Four screws on the top come out fine, but the rest seems to be pretty tight to pull apart. Are there any tricks I need to know about when disassembling the relay?

--Nevermind, I got it. Brute force through some glue. The relays are not soldered, right? It looks like they plug in, which I believe is the part to replace. So I popped out the bad relay #4, and took one of the working relays from my original box that was replaced. Unfortunately I get the same result - relay #4 is still stuck in the on position! The relay I scavenged should be one of the working ones, so I am not worried that I replaced a broken part with a different broken part.

Yes, the relays are soldered.
The part you replaced is probably just the socket.
The relay is a square piece that is soldered on the board.

Ok, I understand now. I replaced the socket.

I replaced the relay. The replaced relay is stuck in the off position. What does that indicate is broken?
