What to do if Aprilaire Fan ERV blower is running, but little or no airflow?
If the Aprilaire ERV fan is running but there's little to no airflow, the issue might be due to incorrect damper position or blocked ductwork. First, make sure that the dampers are fully open. Then, inspect the ductwork for any obstructions and clear them to ensure proper airflow.
How to troubleshoot Aprilaire 8100 Fan if it will not turn on?
If your Aprilaire ERV fan won't turn on, here's what you should check: * Ensure the ERV is properly plugged into a functioning power outlet. * Confirm that the power switch on the ERV unit is in the ON position. * If the unit is wired to an external control, check the wiring connections both inside the ERV and at the control. * As a diagnostic step, connect the two yellow wires inside the ERV. If the fan starts, the problem likely lies within the external control. In this case, troubleshoot the external control following the manufacturer's instructions.
