The buzzing is from a loose winding that is moving. The best way is to throw the unit away and get another unit. The other alternative is to break he unit open and paint the coil.

Can you power a 12 volt dc indicator light from a 16 volt ac door bell transformer?
No, the 12 VDC light must have a DC supply and the transformer voltage as well as being 16 volts which is too high, the output is AC.
Can you run 12 volt DC adapter equipment with a 12 volt transformer?
The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
I have ten 12 volt 10 watt lights what transformer do you need?
To power ten 12 volt 10 watt lights, you would need a transformer with a total output of at least 120 volts and 100 watts.
How do you convert 24 volt trailer lights to 12 volt?
All you have to do is change the bulbs to 12 volts and supply the trailer with a 12 volt power source. If you leave the original 24 volt bulb in the trailer they will only glow at 1/2 of their rated wattage.
How do you convert 12 volt trailer lights to 24 volts?
Change the trailer light bulbs to 24 volts and supply a 24 volt source to power them, in that order.
Will 12 volt transformer work on 3 volt device?
No, it will destroy the 3 volt device.
How do you convert 12 volt to 24 volt?
Use a voltage devider or a transformer.
What do you need to fit a 12 volt base two way radio when the supply is 24 volt?
Step down transformer.
Can you power a 12 volt dc indicator light from a 16 volt ac door bell transformer?
No, the 12 VDC light must have a DC supply and the transformer voltage as well as being 16 volts which is too high, the output is AC.
How do you get 12 volts from an 18 volt transformer?
Reduce the primary voltage and the secondary will also drop.

How can you find out if your 12 volt transformer for halogen lighting is dimmable?
Look at it and find its weight. If it is heavy it contains a transformer and is dimmable. If it is very light and obviously contains no transformer, it can't be dimmed.
I have ten 12 volt 10 watt lights what transformer do you need?
To power ten 12 volt 10 watt lights, you would need a transformer with a total output of at least 120 volts and 100 watts.

What is the formula to convert 240 volt to 12 volts?
If it is AC then you don't need a formula, you just need a transformer.
What is the amp rating of 100va transformer?
The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
How do you convert 12 volt trailer lights to 24 volts?
Change the trailer light bulbs to 24 volts and supply a 24 volt source to power them, in that order.
