What should the primary & secondary voltage be at the transformer? Is it on when the unit is plugged in? The transformer says primary 240v, but it is not...Thank you

PRIMARY means INPUT(from supply side)
SECONDARY means output( to load side)

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

My Electrolux EWF1090 PCB burn.There is one Transformer with Printed "Hartu 717162-51" burn. May i have detail of this transformer ? Primary Side voltage (2 pins) ? Secondary Voltage (3 Pins) ? VA ?

I would investigate what voltage the transformer connects to for primary and what voltage devices connect to secondary. Bring in a temporary power source and read the amperes it draws to operate and find the product of secondary volts and amps to select a new replacement txr

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. There is a step up transformer which steps the voltage up and a step down transformer which steps the voltage down.

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

Hello, I need to replace my furnace control board #HH84AA015. I found the replacement part fairly quickly. Also found a bad transformer,#HTO1BC115 (primary winding indicates 'open' with ohm meter,...

Hello,The transformer (breaks) if the secondary is shorted for any reason.Also a power surge to the house/building will kill it (lighting strike/car hitting telephone pole).It might cause damage to the board.It is cheaper to try a new transformer BUT add a inline 3 amp fuse in the secondary so that will be the last transformer you have to replace(just fuses)if the short is hard to find.Power up the old board & see if it works,unless there is obvious damage.The plug sometimes comes with a new board because there is a wiring change to install it(on some) replacement boards.

Audio video control centre. digatal delayed surronds,model no str-d350z was plugged into wrong voltage,part burned out,can you help

You have not specified the make/model. But if you set is having the transformer as the case may be, and you have plugged into the 220volt with the 120 volt settting, then the transformer would have burned off. If so identify the secondary voltage of the DC cicuit and use a 220volt transformer to replace. If you are not able to identify multiple tappings then you must get the primary of the burned tranformer wound for 220volts. If at all this is aSMPS unit then you will need to replace the full unit as the ratings inthe power will be different.Since you have not specified details of voltage and ratings,I am not able to advice more. Hope you decide. Good day

Whirlpool MH6151XHT-1 - No Power - Stumped

First change all the fuse and check whether it works or not, if it does not work than as per your finding the secondary transformer could be the issue, the secondary transformer tap down the voltage fro 230-240/110 to required control board voltage. the best thing if the unit is opened then the right problem can be found but as per your description either fuses are faulty or the secondary transformer.
