Dead Core vs Used Working vs Rebuilt Automatic Door Controllers
Condition labels drive both technician risk and surplus pricing conversations. Use a shared vocabulary, then verify claims with photos and test notes — not adjective-heavy listing titles.
Why a ladder matters
Automatic door controller assemblies are frequently sold as cores, untested pulls, “tested,” or rebuilt. Those words mean different things to different sellers. A shared ladder reduces expensive mismatches.
Actual dollar value varies by family, revision, demand, completeness, and market timing. This guide does not publish invented averages.
Condition ladder
Dead core / unknown working: board or assembly removed with no credible test. May still have identity value if labels are clear.
Untested / unknown used: visually intact but no stated test method. Treat functional claims as unverified.
Tested used: seller describes what was tested (donor operator, bench power-up, functions checked). Ask for that detail in writing.
Rebuilt / refurbished: who rebuilt it, what was replaced, and how it was verified? Without that, treat as unknown used.
NOS (new old stock): unused but possibly aged. Packaging and date cues matter; still verify the exact identity.
New: current OEM/channel new stock for the exact designation — confirm authorized sourcing separately.
What still changes “value” within a rung
Readable OEM labels and revision marks.
Complete connectors/harness vs board-only.
Missing option modules.
Burn marks, corrosion, or cracked headers.
How commonly that family is confused with another series.
Honest pricing language
Prefer: “Often sold as a repairable/core unit” or “Condition and revision materially affect interest.”
Avoid fake precision: invented sold averages, scraped asking prices presented as comps, or “market value $X” without a dated sold dataset.
If you price inventory, verify recent sold-market evidence for that exact family/revision yourself.
