First time troubleshooting a hot tub. The GFCI was tripping constantly. Narrrowed it down to the transformer plugged into the circuit board. When I disconnected the transformer the GFI stayed on. I'm just wondering if this means the transformer is shot, or if I should be changing the circuit board. How can I test the transformer?

I'm not sure that the secondary side of the transformer (the board) could cause a trip but....I don't know ****.:jester:


My logic says that the transformer is leaking to ground somewhere.

Check the terminals to see if there is any calcium build up from a tiny leak?

Isolate it from ground and test?

Wait....did he start by disconnecting the transformer?

That wont do much good.

No transformer means no power to most if not all the components.

First, disconnect components one at a time.

I started by unplugging everything 1 at a time. Now that I think about it, it is correct that the gfi cannot see the load side of the Tx. I'll replace it, and see if that takes care of the problem. No, I don't have a megger

Did you diconnect the sec. or the pri. of the Tx?

If the Tx has a gnd. a shorted pri could be the problem
