• High-Efficiency 115V Operation: Provides reliable startup and sustained RPM under standard residential voltage loads.
• Durable Construction: Built for continuous duty cycles during peak heating season to reduce premature mechanical wear.
• Universal Application: Standardized fitment for Williams hearth heaters ranging from 20k to 65k BTU.

Is the Williams P501779 compatible with all vented hearth heaters?
This motor is specifically designed for Williams units utilizing the 2102 blower assembly. Always verify the model number on the rating plate of the heater to ensure a proper match with the 115V electrical requirements.

Does this motor include the fan blade or blower wheel?
The P501779 is the motor only. Technicians should inspect the existing blower wheel for balance and debris accumulation during the replacement process to ensure quiet operation.

What are the symptoms of a failing blower motor in a hearth heater?
Common indicators include increased mechanical hum, intermittent startup, or the heater cycling off on high-limit switches due to insufficient airflow across the heat exchanger.
