Pentair 472100 Digital Display Temperature Controller Board Replacement MiniMax NT Series Pool and Spa Heater

Buying guide: Pentair 472100 controller board

This Amazon-listed component is a digital display temperature controller board for Pentair MiniMax NT heaters. The listing also identifies it with catalog part number 6273-0221.

• Use this as a match check only when your heater uses a DDTC-style digital display controller; if the failed component is a millivolt thermostat or separate hi-limit switch, compare those part numbers separately.
• Before ordering, record the board’s printed part numbers and compare them with both 472100 and 6273-0221.

If the old board belongs to another MiniMax generation or controller type, select the matching board rather than assuming cross-compatibility. Controller boards are often model-family specific; verify the full heater label as well as the board marking.
