"...Now pull your head outta the refrigerator and plug it back in. The light should come on, but you should not hear any motors running. Open the freezer and wait a few minutes. If the heaters and terminator are working properly, you may hear sizzling or even see an orange glow. Listen and look carefully. The other thing to look for is a steady trickle of water dripping into the condensate pan underneath the refrigerator. Give it a good five minutes. If it looks like the defrosting system is doing its thang, then the defrost timer was stuck in run mode–replace it."
I get that the problem, here, seems to be that the Defrost Timer ended the cycle after @ 20 minutes. The Fermented Grandmaster didn't address what to do if the defrost cycle ended normally. In the absence of better ideas, I guess I replace the Timer. Maybe I'll see something else when I remove all of that stuff that covers the Timer in Reg's diagram.
