Lochinvar & A.O. Smith 100208463 Tester Assembly
The Lochinvar & A.O. Smith 100208463 Tester Assembly is a critical diagnostic tool designed for service technicians to accurately evaluate variable speed fan motors in high-efficiency Lochinvar heating systems and A.O. Smith air handling units. This OEM fan tester allows for rapid HVAC troubleshooting by isolating the blower motor from the control module, helping to determine if a performance issue stems from the motor's internal electronics or the system's wiring and control logic. Equipped with a clear pass-and-fail indicator, the 100208463 provides immediate feedback on motor speed and functionality, preventing the common mistake of replacing expensive, functional components like the blower assembly or the main control board. As a direct replacement for RLY20119, it is engineered to verify fan velocity and pressure differentials required for proper combustion air proving. Utilizing this diagnostic tool ensures your commercial or residential boilers operate at peak efficiency, maintaining safety and reducing unnecessary downtime during critical service calls.
Key Benefits- Accurate Diagnostics: Effectively isolates variable speed motors to confirm whether the fan or the control module is the root cause of HVAC system failure.
- Prevent Costly Errors: Avoid the unnecessary replacement of expensive blower assemblies by verifying performance first.
- Universal Compatibility: Serves as a direct OEM replacement for part RLY20119, ensuring seamless integration with approved equipment.
- Instant Feedback: Features a simplified pass/fail indicator that streamlines the HVAC troubleshooting process for field technicians.
- Enhanced System Safety: Ensures the fan meets the specific airflow and pressure requirements necessary for safe burner operation.
What equipment is compatible with the 100208463 Tester?
This assembly is primarily used for Lochinvar Power-Fin, Crest, and Knight series boilers, as well as specific A.O. Smith air handling units that utilize variable speed blowers.
How does the pass/fail indicator work?
The tester sends a simulated signal to the motor; if the motor responds by reaching the appropriate RPM and providing the correct feedback signal, the pass indicator illuminates, confirming motor integrity.
Can I use this to test the control module?
While its primary function is testing the motor, it indirectly diagnoses the module. If the motor passes with the tester but fails when connected to the unit, the issue likely resides in the control board or the wiring harness.
