Reznor 194534 Isolator L99H008 investigate airflow issues firstAs a technician, you know that excessive vibration in a unit heater is often a precursor to catastrophic motor failure or cracked heat exchangers. The Reznor 194534 Isolator is a critical OEM replacement part engineered specifically for the venter motor assembly in Reznor UDAP and S30 400 series units. This ventor motor isolator acts as a mechanical buffer, preventing the transfer of harmonic resonance from the high speed inducer fan to the cabinet.
