- Cause: wheel not rotating (motor or belt failure), or condensate/fouling blocking the matrix.Fix: verify rotation and speed; wash the wheel with low-pressure water and a mild detergent; confirm belt tension.
- Cause: exhaust-side temperature dropping below freezing.Fix: enable purge sector, reduce speed, or add preheat. See frost protection methods.
- Cause: worn seals or misaligned purge.Fix: replace seal strips; check purge-sector geometry; confirm supply/exhaust pressure balance.
- Cause: bent wheel, bearing wear, or debris.Fix: rebalance or replace the wheel; service bearings.
- Cause: excessive carryover in a space with odor sources.Fix: increase purge, or switch to a plate exchanger where separation is absolute.
- A semi-annual inspection - rotation check, seal inspection, and a clean if pressure drop has risen >15% - prevents most failures. Track effectiveness and pressure drop at each service to catch drift early.
