What causes York HVAC error code L08?
Error code L08 is caused by outdoor fan motor problems including a failed motor capacitor, burned out fan motor windings, loose electrical connections, seized motor bearings, or physical damage to the fan blade or motor assembly.

Is York error code L08 covered under warranty?
L08 errors may be covered under York's equipment warranty if caused by manufacturing defects. However, failures due to lack of maintenance, electrical issues, or normal wear typically aren't covered. Check your warranty documentation or contact York directly.
