    Jandy JXI heater transformer issues after surge / short repair

    @setsailsoon Yea, checked the igniter the first round and it was good. But in the process of trouble shooting and trying new parts it must have burnt up. At least it was cheap ;-)

    Jandy JXI heater transformer issues after surge / short repair

    @setsailsoon I come back with great news! I took your advice and replaced that Fenwal with a new one from the site you mentioned. I also picked up a brand new main board off amazon. Installed both of them and it didn’t fire up. I was crushed.. but I followed the trouble shooting guide...

    Jandy JXI heater transformer issues after surge / short repair

    @setsailsoon Yea, I flipped the board to the 120va position. Been working on things with the tray in the up position. That flash I was thinking I saw appeared to come from behind possibly from the transformer. Hopefully I’m just imagining that but like you said. At least I can use cheap...

    Jandy JXI heater transformer issues after surge / short repair

    Update: Ran a new 120va circuit, fuse, blower capacitor, transformer and it would run but not fire. I’m assuming that used Fenwal must have cooked on the last meltdown or it’s just a bad unit. It’s “used” from amazon so returning that. I’m thinking I need a new fenwal and just bite the...

    Jandy JXI heater transformer issues after surge / short repair

    @ajw22 interesting. I’m not at home to check. But I know this heater is on the same circuit as my waterfall pump. Rarely would run those together “if ever” but makes me wonder how that sub panel is setup. I’ve also have not run my waterfall since has all happened. Hope that it’s still ok...

    Jandy JXI heater transformer issues after surge / short repair

    @setsailsoon , This is all REALLY good information. I went back and read your story and repair process. Feeling inspired, I'm on a mission now! Quick question. I'm going to run a new 120v circuit to the heater and pull new wire through and everything. Would a standard 15amp breaker work at...

    Jandy JXI heater transformer issues after surge / short repair

    Sdor, on yours check the location of the two incoming 120VA wires and where those are attached to the PCB red and black. On mine they were pointed down rear the bottom vents. So a heavy rain could splash water up into the vent and possibly cross/arc those lines. Sounds like this will be a fun...

    Jandy JXI heater transformer issues after surge / short repair

    Well.. No sign of any shorts I could find. I looked back at my old burned Power Distribution board. The line that was burned was from the black incoming 120va leading to the transformer. Soooo, if you look at what else that black incoming 120va connects to on the other side of that Power...

    Jandy Jxi Heater (Display Blank, But Has Power)

    Did you open it up and double check the LCD wires going into the main board? Just double check one did pop out or anything.

    Jandy JXI heater transformer issues after surge / short repair

    Sorry, I was referring to the Power Distribution board. The board that sends power to the transformer. Was going to test that out without having the transformer attached. I think you may be right that it's in the 120va side of things. Considering that everything hooked up to the 120/240 side...

    Jandy JXI heater transformer issues after surge / short repair

    Now that you mention it. Looking at the burned transformer it does appear to be cooked from the blue wire area. I’ll check the incoming power and double check the voltage coming from the new PCB. Very strange for it to burn up only when it tried to fire up. I figured the transformer would...

    Jandy JXI heater transformer issues after surge / short repair

    Interesting you mention the fuse... Yea it appears to be fine and looks perfect. I thought the same thing, "What is the point of this fuse if it can't protect the transformer?". Did you just fully replace the entire fuse setup for a new 2amp fuse? So those pictures of the Power Distributor...

    Thanks! So it sounds like I'm not the first lol. I'm about to lose my mind with this thing along with all my money. :cry:

    Jandy JXI heater transformer issues after surge / short repair

    Looking for some ideas on this problem I'm running into. At this point it's getting really expensive. Background. I had some sort of surge or short when it appears water from a HEAVY storm may have splashed onto both of the incoming 120va wire caps inside the heater. One of the caps was visibly...
