Maintain consistent airflow and indoor comfort from your Rheem RH1T3617STANJA air handler with genuine OEM replacement parts from Repair Clinic. The RH1T3617STANJA is a Rheem multi-position air handler in the 3-ton nominal capacity class; decoding the model: RH1T identifies the Rheem Classic air handler platform, 36 indicates the nominal cooling capacity class (3 tons), 17 identifies the cabinet width, and STANJA is the production configuration suffix. Rheem and Ruud are sister brands on the same manufacturing platform, making RH1T3617STANJA components interchangeable with the equivalent Ruud air handler at the same configuration. Parts most frequently replaced include the blower motor, blower motor run capacitor, control board, and drain pan float switch. Browse the full Rheem air handler parts catalog.
RH1T3617STANJA: Rheem Classic 3-Ton Multi-Position Air Handler and Ruud Platform Equivalence
The RH1T3617STANJA contains no combustion components; it has no igniter, flame sensor, gas valve, or inducer motor. All service parts are electrical and mechanical: the blower motor and its run capacitor, the control board managing blower speed and heat kit sequencing, the evaporator coil and drain pan assembly, and the transformer. When paired with a heat pump outdoor unit, the RH1T3617STANJA manages both cooling and heating modes; when paired with a cooling-only outdoor unit, a separate electric heat kit is required for winter heating. Rheem and Ruud are sister brands; the RH1T3617STANJA and the equivalent Ruud air handler use identical components. For diagnostic guidance, visit the Rheem air handler repair help section.
Most Replaced Parts on the Rheem RH1T3617STANJA
RH1T3617STANJA Blower Motor and Run Capacitor
The blower motor circulates conditioned air through the duct system in both heating and cooling modes. A motor that hums but does not spin, starts slowly, or runs at reduced speed most commonly has a failed run capacitor rather than a winding fault. Test the blower motor run capacitor with a digital capacitance meter before ordering a replacement blower motor; a capacitor outside its rated microfarad range resolves the majority of blower performance complaints at a fraction of the motor replacement cost.
RH1T3617STANJA Control Board
The control board manages blower speed selection for heating and cooling modes, heat kit sequencing when an electric heat kit is installed, and safety interlock monitoring. A board fault can produce incorrect blower speed, failure to engage heat kit stages, or continuous blower operation regardless of thermostat mode. Test the float switch, transformer, and motor before condemning the board. Browse Rheem air handler control board parts.
RH1T3617STANJA Drain Pan Float Switch
The drain pan float switch protects the installation from condensate overflow by shutting the system down when the primary drain pan fills. A float switch that trips frequently means the primary condensate drain line is blocked; clearing the drain is the correct first step before testing or replacing the switch. A permanently stuck float switch prevents the system from running regardless of pan level.
RH1T3617STANJA Transformer
The 24-volt transformer powers the thermostat, control board, and outdoor unit’s control circuit. A failed transformer causes the entire system to appear unresponsive despite correct line voltage at the air handler. Test for 24 volts at the secondary terminals before condemning the control board for an unresponsive system.

Rheem RH1T3617STANJA Air Handler Parts FAQ
Why is my RH1T3617STANJA air handler not blowing air?
No airflow with the system calling for operation most commonly indicates a failed blower motor run capacitor rather than a motor winding fault. Test the capacitor with a digital capacitance meter before ordering a replacement motor. If the capacitor tests within specification, test the control board’s blower relay output; a failed relay prevents the motor from receiving power even when the capacitor and motor are both functional.
How often should I replace the RH1T3617STANJA air filter?
Replace the air filter every one to three months depending on usage and indoor air conditions. A clogged filter reduces airflow across the evaporator coil, can cause the coil to ice over in cooling mode, and forces the blower motor to draw excess current that accelerates winding wear. Filter maintenance is the most cost-effective preventive step for the RH1T3617STANJA platform.
What is the difference between the Rheem RH1T3617STANJA and a Ruud air handler?
Rheem and Ruud are sister brands under the same parent company sharing the same manufacturing platform. The RH1T3617STANJA and the equivalent Ruud air handler at the same configuration use identical components; parts ordered under either brand designation fit correctly with no modification.
What causes the RH1T3617STANJA to shut down unexpectedly?
Unexpected shutdown is most commonly caused by the drain pan float switch tripping from a blocked primary condensate drain line. Clear the condensate drain line first; if the system resumes normal operation, the blockage was the cause. A float switch that trips with an empty drain pan has failed and requires replacement.
