Fixing a Canon TC80-N3 Intervalometer's Dial

In this video, I show how I diagnosed and repaired my faulty Canon TC-80N3 intervalometer, Canon’s first-party remote timer release designed for professional and semi-professional bodies like the R1, R5, 5D, and 1D series. After years of reliable use, my unit developed an issue with the rotary encoder—turning the dial to adjust frame count or time settings caused erratic or unresponsive behavior. Suspecting oxidized contacts inside the encoder, I decided to disassemble the device and clean it using DeoxIT contact cleaner.

I walk through the full teardown and reassembly process, using basic tools like a small Phillips screwdriver and a plastic pry tool. The fix involved injecting contact cleaner directly into the rotary encoder mechanism, which restored functionality and saved me from buying a new unit. If your intervalometer dial skips, reverses, or fails to register input correctly, this simple cleaning method could bring it back to life.
