How to open up the Power Supply

by BTH
(New Jersey (USA))

My power supply is dead and in my research I see that a lot of times the bridge rectifier has gone bad. What I cannot find is how do you take apart the power supply to access the board to test the components? Unit is out of warranty and I'd hate to bring it someplace and pay $200.00 for service when I can pick up the part for $12.00 and repair it myself. The only logical way I see is to somehow remove the caulking around the back of the unit that will hopefully lead to screws to remove the back. Am I on the right track?

ADMIN REPLY: What model robot?

Open Powersupply
by: Anonymous

Did anyone ever figure out how to open the 9995672. Powersupply for the Dolphin with three selections. Mine worked once, then died. Maytronics sent me a new one under warranty. But, I'd like to open up the old one and tinker with it.

Working Again
by: BTH

Not sure what the problem was, but after a thorough cleaning with a product called Contact Renew + Lube the power supply worked fine after reassembly. Although there was nothing visible I would guess possible corrosion build up on the contacts someplace?

No Schematic

Hi, no schematic is available. These are not generally user serviceable.

Got it open
by: BTH

Well I finally got it open. Had to cut through all the caulk with a Dremel which did expose 4 screws. Now that I'm inside there is more in there than I expected. Is there a schematic available anywhere?

Open Case
by: ADMIN

I have not opened this model case however, other Dolphin power supplies open from the bottom. You may be correct about the caulk but check the bottom. There may be a plastic cover over the screws.
Sorry I can't help any more than that.
