Wireless door chime stopped working

I have a wireless doorbell made by Radio Shack. :-(

Something is wrong with the sender unit.

When the button is pressed, the led lights up but the chimes do not ring.

The chime unit does work, I believe, because it sounds when I change the melody.

I am wondering if it is worth the trouble to see what is wrong with the sender unit?

Thanks.

I forgot to mention, but I live within 1/2 mile of a lake that does have saltwater ingress.

Could just as well be the receiver unit.

The sender is probably little more than an LED, an IC, a crystal and
possibly a transistor to drive the antenna, and, like as not, all
surface mounted, Even if you manage to diagnose the fault, sourcing
replacement component(s) and soldering them is going to be more trouble
that it's worth.

I know the feeling - coincidentally, one of my remote garage door
openers has died today, though in my case I know it's the remote, not
the receiver. The temptation is to spend time trying to figure out
what's wrong, but it's really not worth the effort.

Buy a new one.

Have you tried replacing the battery?

Huh?

If replacing the sender battery doesn't help then try unpowering both
receiver and sender for at least 30 minutes to help reset them both.
Also some older units have the code set by jumper links so you could
check that the receiver setting matches that on the sender - it won't
have changed by just sitting there but contacts can oxidize.

What about moving away from the lake with saltwater ingress?

If DIP switches or jumpers are used to set the code then remove the
battery and check for continuity across the jumpered/switched on
contacts. As it was said, oxidation could be your problem.

I have customers who live across the street from a bay that is part of
the Pacific Ocean - hasn't caused any corrosion troubles for their
indoors equipment, and I hear that ocean has some salt in it...
