About Noritz Code 90 Combustion Air Fix

Noritz tankless water heaters display error code 90 when the computer senses an abnormal combustion airflow condition, indicating that the combustion fan cannot maintain required air-to-gas ratios. In Cornwall, Pennsylvania, dirty blower fan wheels, lint-choked intake cones, blocked flue terminations, or heat exchanger scale buildup trigger this protective warning. Ignoring code 90 causes heavy carbon soot accumulation that can permanently ruin copper heat exchanger fins. Our Noritz technicians clean intake filters, scrub blower fan wheels, inspect vent runs, and check flame current. We eliminate code 90 and restore peak combustion efficiency.

What Our Customers Say

Real reviews from homeowners and business owners we have helped.

Our Navien NPE-240A started beeping error code E003 on a freezing Tuesday morning. Marcus from TWH PRO's arrived within 40 minutes, tested the gas manifold pressure, cleaned the flame rod, and replaced a worn spark igniter on the spot. Having hot water back before our kids woke up was huge.

We went three days with lukewarm showers because our electric EcoSmart 27 kept tripping breakers. The technician tested the continuity of all three heating elements and found two had burned out from mineral scale. He swapped in genuine OEM canisters and descaled the chambers. Steaming showers are back.

Our restaurant dishwasher tripped a sanitation temperature alarm during Friday dinner service. TWH PRO's sent a commercial technician immediately. He cleared a clogged air intake screen on our cascaded Rinnai rack and re-calibrated the water servo in under an hour, saving our dinner service.
