Constant Door Chime

[James Harvie]

Keith. Not sure if this will help you but, I got courious with all this door
chime talk, seeing as mine didn't work either. Mine was a 2 part problem. First
thing I did was to throw in a new set of batteries. I pressed the switch, and
nothing. So I took of the cover of the chime, and jumped the 2 wires and still
nothing. I took the chime off of the wall and dug out the booklet for it and
started reading it. On the back , right under the part where it basicly says
it's going to outlive you, there was what appeared to be some type of rectifier
taped to the book. The scotch tape was rather yellow and brittle so not sure if
it was a factory issue or not, but anyway, I took the circut board out of the
plastic housing, and the groundstrap, for one of the batteries fell out on the
dinette table It looked like someone had dissassembled it and while
reassembling, maybe put a little too much pressure on the tabs ( you have to do
this to get the board back in) I soldered the tab back
on and traced down the location of the diode rectifier It fits in the D9 slot
marked on the circut board. I was going to solder the new one in but decided to
put it back together, I jumped the terminals while it was on the table, and off
it went. I installed it back on the wall and again tried it, with the switch,
and nothing. I removed the switch (mine has a brass rectangled backing plate
about 1 1/4" x 2 1/2" or so, with a white button that looks like it should
light. I threw my ohm meter across the terminals while on the bench, and pressed
the button, and no change on the meter, which told me the switch was open. I
layed the switch horizontally and sprayed CRC Powerlube in the button. I like to
use this lube for a few reasons. It's dielectric, which means you can use it in
electrical switches, and dries after a day or so, so when you spray it inside
your ignition switch, you can put your keys in your pocket, without staining
your clothes.lol I use this on anything that
moves. It works real well on the drawer slides etc. Anyway I started pressing
the button with the meter connected and after about a dozen times the meter
started to move, the switch was stuck open, after a few more times moving it it
was working fine. I tested also for a grounded switch and it wasn't grounded at
the button, it's insulated, I installed it back on the bus and although no light
it works just fine, I think the light is not servicable, it looked sealed. I
hope this helps.

Hey Shane, I just called Nutone. The told me to go to Radio Shack
and pick up diode 1N4002 thru 1N4009. They said any of them will
work. I'll pick one up and let you know what happens.
