What to do if my VENCO VHR 16 has low airflow?
- C
  Craig ClarkJul 25, 2025
  If the VENCO Heating System experiences low airflow, several factors could be at play. First, pressure loss in the ducts might be higher than initially calculated, suggesting a need to review the duct design. Second, clogged or dirty filters can significantly impede airflow; cleaning or replacing the filter is advised. Lastly, excessive leakage on the pressure side of the system can diminish airflow, so inspect doors and duct connections for leaks.

Why is there high airflow in my VENCO VHR 16 Heating System?
- B
  brightmackenzieAug 4, 2025
  If your VENCO Heating System exhibits high airflow, it could be due to a few reasons. Check the duct connections for excessive leakage on the suction side of the system. Also, the fan motors might be experiencing overcurrent, indicating the engine is overloaded, so measure the current drawn by the engine. Another potential cause is a low supply voltage; in this case, consider installing grills.

How to troubleshoot no air flow in VENCO Heating System when the motor isn't working?
- D
  Daniel SheaAug 13, 2025
  If there is no air flow and the motor isn't working in your VENCO Heating System, start by checking the power supply to ensure it's functioning correctly. If the power supply is okay, inspect the fan motor cables at the main controller board to ensure they are tightly connected, as thermal protection might be open. Also, verify the connection of the control panel by checking the socket behind the controller.
