What to do if Vtronic VT-501 has low air flow?
- EelizabethmeltonAug 2, 2025
If the Vtronic Heating System's air flow is low, first, check whether the fan speed is set low and increase it if necessary. If the speed isn't the issue, the filter, fan, or exchanger might be dirty. Clean or replace the filter, and clean the fan and the exchanger to resolve the issue.
