I get typically one of three chimes to sound when the doorbell is rung, occassionally 2 followed by a buzzing sound. Some of the wires were loose and I tightened them, but still don\'t get all the tones. Any ideas on what to do to get all three chimes to ring?

I bought a house built in 1950 with an old Rittenhouse door chime, Model #365. I have no idea if it can be repaired. I don\'t have the front door button. The inner workings are very dirty. Do you think it\'s worth sending to you? Thanks, Kathie

Only one of four chimes works, although we detect a faint electronic buzzing, in sequence, of the other three. For example, we hear Chime A, buzz, buzz, pause, buzz, buzz, Chime A. As cover has been lost, we suspect dust and grime is keeping the other hammers from working.Can the unit be cleaned and…Purchase or Repair:
