Pool Heater Control Board Replacement for Hayward H400FDP HSeries Induced Draft with Display

Pool Heater Control Board Replacement for Hayward H400FDP HSeries Induced Draft with Display Description

Integrated control and display replacement board for pool heaters. Designed as a direct fit replacement for H400fdp and Hseries induced draft pool heaters, this printed circuit board restores control and display functions to the unit to normal operation. Key benefits Restores full control and display functionality so the heater can be used again after a failed PC board. Direct replacement compatibility with H400fdp and Hseries induced draft heaters for a straightforward swap. Integrated design reduces wiring complexity by combining control electronics and the user display into a single module. Matches original board form factor and connector layout to simplify installation and minimize modification. Helps recover diagnostic and status readouts used for troubleshooting and maintenance. What it does Serves as the main control and display board, handling user interface output and control signals for the heater. Provides the display surface for status indicators and error codes so technicians can diagnose issues. Interfaces with existing sensors, switches, and connectors on compatible induced draft pool heater models. Important attributes Function: integrated control board and display board; replaces the original PC board in compatible models. Compatibility: designed for H400fdp and Hseries induced draft pool heaters; confirm model and part number before installation. Size and fit: compact PCB layout that aligns with original mounting points and connector positions for direct replacement. Material and construction: printed circuit board assembly with standard board components and connector interfaces. Performance: intended to match the original control and display behavior to maintain expected heater operation. Typical use scenarios a failed control board when the heater will not start and the display is blank, restoring operation without replacing the entire heater. Swap in the replacement board during routine service when the original board shows intermittent faults or corrupted display output. Use in a maintenance to troubleshoot and verify heater function by restoring diagnostic readouts and control responses. Notes Verify the heater model and part number before to ensure compatibility. Installation should be performed by a qualified technician familiar with pool heater electronics and safety procedures.
