Migliaccio & Rathod LLP is investigating reports that LG mini-split systems are frequently displaying the CH38 error code, indicating refrigerant charge or pressure issues, even after professional installation and repeated service. Homeowners describe the code as recurring or “sticky,” often returning shortly after repairs and causing extended HVAC downtime.
Recurring Refrigerant Errors in LG Mini-Split Systems
LG advertises its mini-splits as high-performance, energy-efficient HVAC solutions. However, user complaints and LG’s own Help Library documentation suggest:
-
CH38 error occurs frequently, often shortly after system startup or installation
-
Power cycling provides only temporary relief, with the code returning within days
-
Multiple technician visits fail to resolve the issue permanently
-
Users dispute LG’s claim that the problem stems from low refrigerant charge, especially in professionally installed units
LG’s support pages confirm that CH38 relates to refrigerant level or electrical instability, yet the prevalence and persistence of the error raises concerns about deeper defects in metering or pressure management systems.
Legal & Consumer Protection Concerns
This defect may constitute:
-
Latent manufacturing or materials defect – inconsistent charge control across units
-
Breach of warranty – repeated repairs without resolution
-
Deceptive marketing – systems advertised as reliable but affected by recurring faults
Consumers impacted by CH38-related service issues may be entitled to reimbursement for service costs, component replacement, or extended labor coverage.
