Pentair/Sta-Rite 42001-0107S Transformer 115V/230V

A reliable heater is essential for any Canadian pool owner who likes to open early, close late, and enjoy every moment possible in the water. A pool or spa heater is a big investment, and when it breaks down, pool owners often worry about the expense and time required of finding a replacement.

Part of what has made Pentair one of the most reliable names in pool and spa heating is the fact that they have designed their heaters for a long life. Beyond quality design and manufacturing, Pentair has also made their heaters easy to diagnose and easy to repair, and has designed a full line of replacement parts that can get your pool heater functioning with no problem.

A heater with a bad transformer requires a replacement, and with the 42001-0107S Pentair Transformer, you can get your pool or spa heater up and running fast. This transformer is suitable to replace defective parts in MasterTemp and Max-E-Therm heaters.

If your pool professional has diagnosed the need for a new transformer, be sure the 42001-0107S Pentair Transformer fits your existing pool or spa heater, and you'll be able to get your heater up and running with just a quick service call.
