Rheem Rheem RTGH-95DVLN Prestige 9.5 GPM Condensing Tankless Gas Water Heater 61 Error Fix: Combustion Fan / Blower Motor Failure

The combustion fan (blower) motor is not reaching the expected RPM or has failed entirely. The fan provides forced-draft combustion air and is essential for safe, complete combustion. Without proper fan operation, the unit cannot light or maintain combustion safely. Causes: motor bearing failure (grinding or high-pitched noise from the fan), debris lodged in the fan housing, a failed motor winding, or a PCB failure in the motor control circuit. Check for obstructions in the fan assembly. Verify motor voltage from the PCB matches specifications. Replace the fan motor if it does not run or operates at incorrect speed.
