No power at the control panel - no power to the 24v transformer

Hello TFBs,

I am facing a problem with my pool control panel not turning on - I opened the front panel and replaced the fuse but that did not fix it. I checked for power at the transformer AC side and there is ``NO`` power.
the battery 9v was dead as well - going to replace that.

Welcome to TFP.

The 9V battery just keeps the clock alive when there is no power.

Checking voltage at the relays does not tell you there is power to the board transformer. That is all I saw you do in your video.

Please post pics of your panel so we can study the wiring and see where the transformer power connection is.

If you can point out the transformer power wires and exactly where it gets its power from it would be helpful.

Step back and take a pic of the entire panel.

Your video showed you have no power on the black wire of the transformer. That is the hot input power to the transformer.

The white transformer neutral line should not connect to the ground bar. There should be a separate neutral bus bar in the panel or all the neutrals in the panel should be wire nutted together..
 
You really need to get a good electrician to get everything wired up correctly.

You have a jumble of wires and it is difficult to follow what is what.

You have the grounds acting as a neutral and it looks like you have at least one live wire loose in the cabinet.

Poking around with a voltage detector is not the way to diagnose the issue.

So looks like the problem is no power to the transformer primary - is that normally live and neutral - the power is coming from a dipole switch. Can I just power the transformer primary directly with live&neutral and check?

@JamesW
getting an electrician is what I will have to do once reach the point of giving up :)

Get an electrician to help you fix your panel.

We cannot help you with the information you are providing.
 
The transformer needs 120 with a black (Hot) and white (Neutral).

Check for 120 volts going to the transformer.

The white neutral needs to go to the neutral bar at the main panel or subpanel.

The white cannot connect to the green ground bar.

The breakers should be GFCI breakers.

You need to identify the wires coming into the Power Center and the wires going out to each piece of equipment.

There should be at least 2 hot wires, 1 neutral wire and 1 ground wire.

The two hot wires should have 240 volts line-to-line and each hot should measure 120 volts line to ground.

The pump is probably two speed and it needs 3 hot (High, Low and Common) and one ground.

Can you create a diagram of what wires are coming in and what wires are going out to each piece of equipment?

The relay gets power to the Line terminals (2) and (6).

When the relay coil (Top terminals going to the Relay Socket) gets 24 Volts DC, the relay closes Line 1 to Load 1 and Line 2 to Load 2.

Check for 240 volts to the line terminals.

The filter pump relay should be plugged into the Filter Pump Relay socket.

The two speed pump relay should be plugged into the Aux 2 relay socket.

Can you show the breakers going to the Power Center?

Can you show all equipment and the pump motor label?

If the two speed motor is the filtration pump, plug the relay coil wires for the standard relay into the filter pump relay socket.

Next, plug the two speed relay coil wires into the Auxiliary 2 socket.

Finally, turn on DIP switch 2 to set the circuitry to two speed operation.

This will interlock the low speed and high speed together.

If low speed is activated, the control will turn on high speed first for three (3) minutes (to prime the system) before switching to low.

It looks like the pump is a Hayward Super II and the two speed relay indicates that it is probably a two speed pump.

It looks like there are some loose or disconnected wires in the panel.

Did anyone recently work on the equipment and maybe disconnect the wires?

Thank you so much for the detailed explanation James - :)

There was a pool guy who came a few years back and replaced the motor - I think it must be his doing. Will try and figure it out with the help you gave me - much appreciated

Note: Make sure that you are 100% sure before making any changes.

Maybe they switched to a single speed motor?

I do not know what you have.

You need to go over everything and verify that it is wired correctly and that you are getting the correct voltages.

Maybe a breaker is bad or tripped?

Note: Make sure that you are 100% sure before making any changes.

I recommend that you get a qualified electrician to help you verify that everything is safe and up to current codes.

Maybe a breaker is bad or tripped? breaker is in the house main panel not tripped - no breaker in this panel.

After spending some time at the main breaker panel(not pool, house) and testing the voltages - all breakers are fine and showing 120v / 240v.

The live red wire connected to the filter pump has no voltage. Tracking the wire - it goes into the mud (ground) -- will look to trace it ( will post a pic)

also, I connected the 24v transformer neutral to a neutral inside the panel from which neutral is wire nutted.
I tested the hot of the transformer temporarily connecting to the live/hot and the panel turned on. So the transformer looks to be good


"There should be at least 2 hot wires, 1 neutral wire and 1 ground wire."
There are 2 red/hot wires coming into the panel from GFCI & switch - but only 1 measures 120v the other red which is connected to the pump has no power(volts). I think this may be the problem - If it is then I have to do some cable tracking to see where it is broken.
