Emerson Rittenhouse C8846R Door Chime Controller

The Emerson Rittenhouse C8846R is an 8‑note electronic door‑chime base that functions as a small control board converting wall voltage into tuned tone outputs via relays and tuned resonators. Common failure modes include degraded power‑supply capacitors, burnt or corroded relay contacts, and failing output transistors that cause intermittent or no chime playback. First‑check diagnostics: verify the 16 V transformer output with a multimeter; inspect all capacitors for bulging or leakage and replace any suspect units; test each relay coil and contact for continuity and proper operation before proceeding to component replacement.[oss-gpt-20b] Post Comment
