at the cost of some equipment today they are throw away when the dont work and buy new. if its a small transformer you might try radio shack multi volt unit . bring in old transformer so the can match speaker side of wire.

You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much.
Good Luck.

Hi there bud , The Blown Fuse could of been cause by maybe a Power Surge or a Power Trip...If this hasnt happened then it could also be due to faulty wiring in the Subwoofer itself when it was being produced.
What you can do is , take it back to the shop and have them replace it...Dont inform them that you had opened it as then they will delete your warranty...
Hope this helped bud
Happy new year

I have Sumheat S3 Hayward pool heater I also do not have 24 V output between the blue and yellow cables coming from the transformer. Do I need to replace the transformer? Thanks Cecilia

The 24v is called the secondary and sometimes called the out-put. Make sure you have 240v on the primary, sometimes referred to as the in-put. If you have primary voltage then you should have secondary voltage, if not then replace transformer. Make sure the secondary, 24v control fuse is the correct size and present. If the secondary is shorting together or to ground somewhere, it will cause damage to the transformer.

How to measure Voltage in Transforme for Fitness Treadmill

Transformer Test Procedure:1). Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.2). Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)wires as shown. Normal reading: 110V. This shows that there is power to the transformer.3). Test transformer output by probing on secondary (output) wires: black and black, white and white,orange and orange, yellow and yellow

Transformer Test Results :1). If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power to the drive board. 2). If there is voltage across primary wires but none across secondary wires, the transformer is bad.Replace it.

Transformer Wire Colors Normal Voltage Value:
Red and Red 110 VAC.
Black and Black 11-13 VAC
White and White 11-13 VAC
Orange and Orange 27-29 VAC
Yellow and Yellow 10-12 VAC

No readout on on board. No on light when pushing on pool button

No power being sensed, check main.
if power to heater, check for voltage at transformer: both primary and secondary.
if primary reads whatever voltage you supplying heater, then check secondary, if 0, bad transformer. If 24-28 volts, then circuitry is bad, further diagnostics required.

How to test for bad transformer

  1. To test a transformer you need to know what type of transformer it is first. There is a step up transformer which steps the voltage up and a step down transformer which steps the voltage down.
  2. You will still test the transformers the same way for step up and step down transformers. If it is a step up transformer apply the incoming power to the transformer or plug it up. Now take your multimeter and place it on the AC volt scale and test the voltage if the voltage on the data plate says the transformer should step up to 220 volts and it doesn't then your transformer is bad.
  3. Now repeat the same steps for a step down transformer. Plug up the incoming or primary power and test voltage on the outcoming or secondary side the voltage should step down to the proper value. If you don't read any voltage on the secondary or outgoing side then the transformer is bad.
  4. To read the voltage place the two meter leads on the secondary side, or the side you will plug your equipment into. If the secondary side is an outlet then place the two meter leads into the top two slots in the plug and read voltage. You also want to make sure the incoming power is working as well. Otherwise you will be reading a bad reading every time.

I have a LG LRE30453SW Electric Range and the relay pcb keeps going bad. I get an F7 error when starting the oven. The first time I noticed the black line in, from the power terminal, to the relay pcb was...

First, check the 220v line and breakers are properly grounded and that you are getting a constant 220v at the plug. Then you will need to check the transformer on the unit.To test a transformer you need to know what type of transformer it is first.

If all that looks good, then you will need to replace the control board. Here is a link to the parts for your range.

I have a logitech x-530 5.1 system that doesn't work. when i pulled the sub woofer apart, all I found was a blown fuse. What caused the fuse to blow? Also,what would be the voltage of the secondary side?

The mains transformer in my Logitech x540 has blown (oc on the primary). I've taken it out and its a simple single coil primary and secondary, but there are no markings on it to indicate the secondary...

You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much.
Good Luck.

What are the secondary voltages off the transformer supposed to be?

The secondary voltages of a transformer are stepped down voltages. For example a transformer might be stepping 120 volts AC down to 25 volts AC in the secondary. Which then would be rectified by a bridge rectifier in the power supply and converted to DC Voltage which would be used to bias transistors or tubes and other electronic components. The amount of voltage that is output for use is determined and calculated by the engineers designing the amplifier or pre-amp.
