Product details
The Pentair 42001-0107S is the dual voltage transformer kit for the Sta-Rite Max-E-Therm and Pentair MasterTemp heater electrical system. It is rated 115/230V, so one part covers a heater wired either way.
What the transformer does
The heater runs its controls on a low voltage circuit, and the transformer is what supplies it. When the transformer fails, the incoming power is still there but nothing on the panel wakes up, which is why a heater that appears completely dead is often a transformer rather than anything in the gas train.
Coverage
It is listed under the Sta-Rite Max-E-Therm SR200, 333 and 400 and the Pentair MasterTemp 175 to 400, which share the same heater electrical system. Confirm the part number on the transformer you are removing, since these heaters ran over a long production period.
