    Replacing transformer Pentair Minimax NT heater

    Amazon.com: Pentair 471360 Dual Voltage Transformer With Circuit Breaker Replacement for Pool And Spa Heaters: Patio, Lawn Garden

    Looks like my transformer went out, I ordered this part...is there anything else I need to install this new transformer?

I hope someone else benefits from my trial and error and saves some money. Regards,

    Kill the power to the unit.

    Screwdriver and wire nuts.
