soft ding with no dong - needs replacing!

[telectrix]

if you want to keep the illuminated bell push, you must use a tranny, not batteries. the light in the bell push will flatten the batteries overnight.

yeah, it does seem that way to me,
so I wonder if there is anything that can be done to fix it? I suppose if I found the transformer I could see if there is a way to output a higher voltage from it?

How the Hell can you "lose" a doorbell transformer??

I'm mystified.

There are some bell transformers that can be mounted on the DIN rail inside the consumer unit. Maybe that's the case here?

i would think it would be one of those old bakelite trannys, close to the DB. judging by the age of the chime unit itself. if OP posted a photo of the DB and surround, we might have an idea. still think it's less trouble to fit a wireless bell than type a post.

Yes, I thought so too and the CU is probably one of those old Wylex jobs with rewire able fuses - you know, the sort that sometimes needs the main switch replacing after the Scouse sparky has poked about with it - but as the OP doesn't seem able to find it, I thought maybe it had been upgraded with new CU and transformer on the DIN rail

and whilst your there....you might just find an ancient cutout with fused neutral.....like i did the other day over Bradford....

hi guys
thanks for the responses, the door bell is on a new wall, which is why it is 5m or so further from the old front door.
there is a photo of the only other thing I know is related to the door bell in my first post... could the transformer be UNDER this unit?

I do not want a wireless system because I would lose having an illuminated doorbell. We have face brick and I am not going to start drilling holes, chasing new wires etc... just want the doorbell to work properly. I dont mind buying another one, but want to keep the existing illuminated bell.

thanks again for your support, perhaps I should get an electrician to come in (

Check all your connections especially where the builder has extended the wiring, as they do have an uncanny knack of doing a crap job where electrics are concerned, coz anyone can do it.
post a pic of your fuse board up, and we may be able to shed some light on your illuminated bell push

hi there
all the connections the builder made are now either under concrete or inside a brick wall.
the fuse board is relatively new and definitely has no doorbell specific trip switches... I think its a transformer i need to find?

Good lad!!!

It's always a pleasure to meet a quick learner.

There are various possibilities for the failure for your doorbell, the spring could have become tired or broken and need replacing, you have high resistance connections in your supply cable / switch transformer supply cable. Your cables are too thin to carry the required current, your transformer is now too far from your bell to supply the required voltage, the volt drop from the bell push is reducing the voltage in the same way.

A standard bell transformer is not adjustable, they tend to be 12V supplies. The capability to supply current is different for different transformers.

If the transformer is not man enough then it will be slightly difficult for you to get a more powerful replacement as they are not standard items.

A bell transformer could look like any of the attached pictures.
Old bell transformers were generally placed either near the bell unit or near the consumer unit. Occasionally they would be in the roof space above the door or in the attic.New bell transformers can be fitted into the consumer unit, you could also have a transformer looking like a laptop power supply, but much less likely.

The builder should not have covered the connections for the door bell as they should always be accessible (unless they were permanently fixed, so it may be worth looking again.
