What diode goes with the heath zenith TR-0070-BX door chime?

Most Heath Zenith product manuals are available here: https://www.heath-zenith.com/support/owners-manuals . Searching for the SL-6273 found two versions of the wireless MP3 door chime. The direct link to the manual for the SL-6273-00 is https://www.heath-zenith.com/system/spree/documents/attachments/000/000/839/original/205371-02A.pdf?1436551434 .

Put the batteries in the door chime. To transfer an MP3 to the door chime, connect it to a computer with a USB cable. Open the folder to view files and drag the new (short, <= 20 seconds long) tune into the folder. Eject the door chime (like any USB hard drive) and remove the USB cable from the door chime.

Next press the Tune button to cycle through the tunes on the door chime for the front door chime. Stop when the desired tune is played. That will be played any time the front chime is pressed. If you add the jumper to pin 8, the door chime will ding as that is the rear rear door sound. For the front door, make sure that the switches (1-7) on the push button match those for the door chime.

I hope this helps.

Heath-Zenith (I beleive they bought DESA) makes a battery remote push button bell that says its compatible with all Heath Zenith chimes. I bought one at Home Depot and it worked for my SL-6195-RX. (an on line doorbell seller and the Home Depot assoc all said it wouldn't work.)
UPC is 16963961975.
Item also shows a code "11G43" on a sticker on the back of the package.

The unit is receiving electricity so low-voltage transformer and button are working correctly.
Only suspect left is door chime itself.
Check that voltage of transformer matches voltage of chime.
Use cheap multimeter from home center and check voltage at chime, or check transformer.
Doorbell transformers are usually located in basement or garage or attic, and most are hardwired into octagon box.
There are no replacement parts for door chimes.
Buy new one, or contact seller for refund if this is new chime.

There is a little "diode" that should have been provided as part of the unit...it's a little wire with a B-B-sized circuit in the middle that has to be connected to the push-button at the door. This "extends" the circuit from the button to the chime unit for the full 8-notes. Hopefully you still have that part (I just about threw out mine before I read the instruction manual thoroughly. My diode just "shorted" after I power-washed my house...and I am in search of that particular part. I contacted Heath Zenith...hopefully they will give me a solution on how to get only that part. In any case, you need that diode to get the chime to play correctly.

Possibly check the outdoor push button. It may be possible that it has moisture in it causing a short.

here is a link to the owners manual i hope it helps, but i don't think it gives u the option to play all the tunes, just one at a time

Change pin configuration on plugin bell and the remote.
The pin configuration should match
