Unbranded 42002-0007S Restored Tools sku-18308054749

This Unbranded Restored Tools control board kit, SKU sku-18308054749 and UPC 769284929093, contains the 42002-0007S replacement board (461105) and a 472610Z switch membrane pad for Pentair MasterTemp heaters. It uses upgraded solid-state capacitors and power chips, high-precision soldering, an improved optocoupler and a regulated power module.

The module provides overheat, overvoltage and short-circuit protection; the upgrades are intended to improve durability, output control and operating efficiency. The kit fits Pentair MasterTemp NA and LP series pool and spa heater electrical systems, including MasterTemp 200, 250, 300, 400 and 400HD control boards.

It also fits Sta-Rite Max-E-Therm SR200NA, SR333NA, SE400NA, SR200HD, SR333HD and SR400HD control boards. A replacement board may resolve erratic heating, failure to power on, persistent error codes, unresponsive controls or incorrect temperature regulation. Before replacing it, check the temperature sensor, pressure switch and igniter, since faults in those parts can resemble board failure.

The seller offers diagnostic help, says it will respond to installation or operating issues within 12 hours, and provides a 1-year return and exchange policy with a period longer than Amazon's standard.
