Jandy Aqualink Died

[Cmbott88]

My PCB from 2007 appears to have died. I tested the transformer, and I am getting 18vac out of it. I know I should be getting 24 to 28. I definitely have power coming to the sub-panel as I was able to bypass the relays so that I can continue to run my pool manually. So where I am confused is that I am getting power out of the transformer....just not the amount it should be getting. Before I buy a replacement transformer or board, is there anything else that I should check?

Thanks!

Welcome to TFP.

Sounds like a bad transformer.

@setsailsoon thoughts?

88,

Welcome and sorry you're having trouble. I agree with Allen, make sure you're getting full power to the transformer primary windings first. There's always a possibility of a connection issue. If the primary is at full voltage then your transformer has failed. Did you have anything unusual happen like lightning storm or power surge or any other major failures with the pump recently?

I did have a actuator apparently short out.... wasn't moving and was very hot.

Could be related to that issue. Reason I ask It's a little unusual for the transformer output to be reduced instead of shorting out. Have you been able to verify what the voltage is on the primary windings of the transformer?

I haven't yet.... we are getting bands from the tropical storm/hurricane right now up here in south jersey.... I will post as soon as I have been able to

There is a fuse on the back side pf the main board that should be checked.

yea....already checked that.... thanks, though... appreciate it.

Ok, here's my update guys.... sorry for the delay. we have had a ton of storms come thru.... other things took precedence. in any event, I am getting 120 to 121 volts going into the transformer and 18.0 to 18.2 coming out. before this issue arose, there was a jandy valve actuator that apparently had a short (wouldn't turn and was hot as heck). So, at this point, I am leaning toward the transformer having been "partially blown" as a result of the short.

Yep. Go w the transformer. Check for any dead shorts in the 24 vac circuit before you plug in anything. If you get any shorts repair/replace components as needed.

Fingers crossed!
