Bought this inexpensive wireless door chime couple of months ago which has a transmitter unit (where you press the button) and the receiver unit (the chime normally located inside the house). An example of such a unit : Amazon.com: Sunnybell ST60 3-Tone 16-Channel Wireless Door Bell,Door Chime With Strobe Light: Home Improvement
Recently it stopped working and thinking that the transmitter battery is flat, I changed the battery but it stopped working again after a day (the receiver battery is ok).
While trying to investigating what went wrong, I accidentally inserted the supposedly flat battery in reverse polarity, pressed the button, which of course gave no sound. But when I reconnected the battery in the correct polarity, the transmitter worked and the receiver unit chimed. This worked for a few presses, and the transmitter went dead again. If I repeat the above, I can get the chime working though only for a while.
Any idea what is happening? Also, which part is not working? If it is just a bad capacitor, I am wondering if it can be easily repaired.
Thks!
