Restore dependable heating performance to your Rheem RGTA-09EZAJS/Serial: EH furnace with genuine OEM replacement parts from Repair Clinic. The RGTA-09EZAJS/Serial: EH is a 90,000 BTU upflow condensing gas furnace from Rheem’s Achiever 90 Plus series, achieving over 90% AFUE through a secondary heat exchanger that produces acidic condensate during normal heating operation. The condensate management system — including the condensate trap and PVC drain line — is the most important preventive maintenance focus on this model. Repair Clinic stocks genuine Rheem OEM parts for the RGTA-09EZAJS/Serial: EH including the Rheem igniter parts, Rheem flame sensor parts, Rheem draft inducer motor parts, Rheem pressure switch parts, and Rheem control board parts.

RGTA-09EZAJS vs RGRA-10EZAJS: Same Achiever 90 Plus Condensing Platform at Different BTU
The Rheem RGTA-09EZAJS at 90,000 BTU and RGRA-10EZAJS at 100,000 BTU share the same Achiever 90 Plus condensing platform but use inducer motors sized for their respective output classes. The condensing-rated inducer on the RGTA-09EZAJS must tolerate moisture from condensate-laden flue gases — a standard 80% non-condensing inducer must never be substituted. A blocked condensate drain is the single most common cause of pressure switch faults on the RGTA-09EZAJS. Annual flushing of the condensate trap before the heating season prevents this fault from recurring. The Rheem furnace troubleshooting guide covers Achiever 90 Plus fault code interpretation.
Most Replaced Parts on the Rheem RGTA-09EZAJS/Serial: EH
Condensate Trap for the RGTA-09EZAJS/Serial: EH
Annual flushing of the condensate trap at the beginning of the heating season is the single most cost-effective preventive maintenance step for the RGTA-09EZAJS/Serial: EH. Algae growth in the trap during the warm-weather idle period causes most pressure switch fault calls at early heating season startup on the Achiever 90 Plus platform. A trap that drains slowly or overflows has a partial blockage that will worsen without cleaning.
Rheem RGTA-09EZAJS/Serial: EH Draft Inducer Motor
The condensing-rated inducer on the RGTA-09EZAJS/Serial: EH is designed to tolerate moisture from condensate-laden flue gases and must not be substituted with a standard 80% AFUE inducer or an inducer from the larger RGRA-10EZAJS platform. Bearing failure presents as grinding at startup during the pre-purge phase, before the gas valve opens. An audible bearing should be replaced before seizure causes a complete heating failure.
Pressure Switch Assembly for the RGTA-09EZAJS/Serial: EH
Inspect and flush the condensate drain trap before replacing the pressure switch on any condensing furnace. The vast majority of RGTA-09EZAJS/Serial: EH pressure switch fault calls trace to a blocked condensate drain rather than a failed switch diaphragm. Replace the switch only after confirming the drain system is completely clear and the fault persists.
Flame Sensor for the Rheem RGTA-09EZAJS/Serial: EH
The flame sensor monitors the main burner after ignition by passing a micro-amp signal back to the control board to confirm sustained combustion. An oxidized sensor rod disrupts this signal and causes the furnace to ignite and shut off within seconds, repeating until safety lockout. Annual cleaning of the sensor rod with fine steel wool extends service life on the Achiever 90 Plus platform.
RGTA-09EZAJS/Serial: EH Control Board
The control board manages condensate trap monitoring, inducer pre-purge timing, ignition sequencing, and safety switch inputs specific to the Achiever 90 Plus condensing platform. It is not interchangeable with boards from the non-condensing Rheem RGPH Classic series. Document the LED fault code before ordering any replacement component.

Rheem RGTA-09EZAJS/Serial: EH Furnace Parts FAQ
What is the BTU output and efficiency of the Rheem RGTA-09EZAJS/Serial: EH?
The RGTA-09EZAJS/Serial: EH is a 90,000 BTU upflow condensing gas furnace from Rheem’s Achiever 90 Plus series, achieving over 90% AFUE. It is the 90,000 BTU configuration on the same condensing platform as the 100,000 BTU RGRA-10EZAJS.
Is the Rheem RGTA-09EZAJS/Serial: EH the same as the Ruud UGTA series?
Yes. The Rheem RGTA and Ruud UGTA designations reference the same condensing furnace platform sold under different brand names. Service parts are fully interchangeable between Rheem and Ruud designations at the same BTU class.
Why does my RGTA-09EZAJS/Serial: EH produce a pressure switch fault at the start of the heating season?
Early-season pressure switch faults on the RGTA-09EZAJS/Serial: EH are almost always caused by algae growth in the condensate trap during the warm months when the furnace was idle. Flush the condensate trap with clean water before the first heating call each season to prevent this recurring fault.
What type of venting does the Rheem RGTA-09EZAJS/Serial: EH require?
The RGTA-09EZAJS/Serial: EH is a condensing furnace requiring Schedule 40 PVC venting for both exhaust and combustion air intake. Metal B-vent is not appropriate. Horizontal PVC runs must slope back toward the unit so condensate drains toward the furnace rather than pooling in the run.
