There is only one return vent, below the left crisper drawer, and it is clear.
I just tested the defrost timer and there is no continuity between ground terminal and any of the other three terminals, whether timer is on or off. That looks to be the likely suspect.
6 hours later. Parts guy checked defrost timer and it was bad. Replaced it. Frig is still short cycling - runs for 5 minutes and shuts off over and over - never long enough to cool the frig cabinet.
Two techs said it is either the compressor (read as New Frig) or the compressor relay.
The next day: replace compressor relay ($38). Frig running normally. Problem solved.
