Emerson Rittenhouse 577 Doorbell Controller Repair Service

Professional diagnostic and board-level repair service for this Emerson Rittenhouse 577 Doorbell Controller.

Emerson Rittenhouse RC‑577 Door Chime is a vintage electromechanical chime unit that uses a series of tuned resonators and a motorized drive to produce the classic door‑bell tone. The most common failure on this model is a defective rheostat (part numbers 1406417 or 135‑51), which prevents proper voltage regulation and stops the chime from sounding. First‑check steps: verify power supply continuity and correct voltage at the unit terminals; inspect the rheostat for mechanical wear, broken contacts, or burnt resistive track; then test the motor windings for open/short conditions before proceeding with component replacement.
