comment What would cause my furnace to only work with the filter removed?
The problem turned out to be that the gas feed was set too high causing the furnace to overheat. The technician reduced the gas flow and the problem went away and the furnace has worked perfectly ever since.

comment Why would an outdoor floodlight only work in test mode?
I have six of these (DESA Specialty Products 5316-A) motion sensors, half on one circuit and half on another. One circuit works fine but the three on the other circuit have exactly the problem described by Jack. It seems unlikely that the three on one circuit would go bad while the ones on the other circuit remain working. Note that these problematic sensors are on a light switch.

How does one test that the blower has sufficient power?

I usually use the cheap filters, but I tried a more expensive one and that did not help. I may try one of those really cheap ones (fiberglass?) that look as though they only filter the largest particles.
