Compatibility & Fitment

This kit is intended for the Universal H-Series low-NOx pool and spa heater models manufactured by Hayward. Before purchasing, verify that your heater’s model number falls under the H-Series (for example H150FDN, H150FDP, H200FDN, H200FDP, H250FDN, H250FDP, H300FDN, H300FDP, H350FDN, H350FDP, H400FDN, H400FDP) and that the original blower kit part matches this replacement. Installing the correct blower helps maintain proper combustion, reliable heater start-up and safe operation.

Installation Instructions

• Turn off all power to the heater and shut off the gas supply line before servicing.
• Allow the heater to cool and relieve any pressure or gas residuals per manufacturer service instructions.
• Remove the old blower motor assembly and mounting plate; disconnect wiring and controls carefully, noting original orientation.
• Install the new blower kit: mount the fan/motor assembly, secure hardware, reconnect wiring, and verify proper alignment and clearance.
• Restore gas and power supplies, then perform a test ignition cycle; monitor for correct blower operation, combustion sequence and absence of error/fault codes.

Troubleshooting & Maintenance Tips

• Blower fails to start: Check power supply, motor wiring, fuse or breaker, and ensure the blower connector is securely attached.
• Excessive noise or vibration: Confirm the fan is mounted correctly, balanced, and no foreign objects obstructing blower wheel.
• Heater faults out or doesn’t maintain flame: The blower may be under-performing; verify correct blower kit installation, airflow path and no intake or exhaust blockages.

Maintenance Tip

Inspect the blower assembly annually during heater service. Clean any dust or debris build-up, check mounting bolts for tightness, and ensure the blower motor cooling vents are clear of obstruction. Replacing worn blower kits like the FDXLBWR1930 proactively can help avoid heater downtime and premature component failure.
