Louvre Deformation During Heating - ASTG24KMCA

Historical QA investigation - cause not identified
A quality assurance problem report identified a case where the airflow louvre became deformed approximately two months after installation while the unit was being operated in heating mode.

Affected Unit

ModelASTG24KMCA
Serial numberE026401
Quantity1 unit
Operating modeHeating

Reported Problem

Approximately two months after installation, the unit's louvre was reported to have become deformed during heating operation.

Investigation

FGL carried out an investigation using a sample unit in an attempt to reproduce or identify the cause of the louvre deformation.

Investigation result: The cause of the louvre deformation could not be identified.

Conclusion

No confirmed manufacturing, installation or operating cause was established from the investigation.

The available report only confirms that:

  • The affected model was ASTG24KMCA.
  • The reported deformation occurred after approximately two months of service.
  • The unit was operating in heating mode when the issue was observed.
  • FGL could not determine the root cause.

Service Guidance

  • If louvre deformation is reported, confirm the full indoor model and serial number.
  • Photograph the louvre in both the stopped and operating positions.
  • Confirm whether deformation is present only during heating or is permanent.
  • Inspect for physical obstruction, external heat exposure or evidence of impact.
  • Confirm that the louvre moves freely and is not binding against the fascia or surrounding components.
  • Where no external cause is evident, escalate the case for technical review.

Information to Collect if the Issue Reoccurs

ItemDetails Required
Unit identificationFull model and serial number
Operating modeHeating, cooling, fan or auto
Operating historyApproximate age of unit and when deformation first appeared
EvidencePhotos and video of the louvre during operation
Site conditionsAny nearby heat source, obstruction or physical interference
Important: The original investigation did not establish a confirmed root cause. Avoid attributing future louvre deformation cases to a specific manufacturing defect without supporting evidence.
