Migliaccio & Rathod LLP is investigating widespread reports of recurring issues with Mitsubishi Electric mini-split and multi-zone HVAC systems, specifically the GL and MXZ series. Despite claims of long-lasting performance and reliability, many consumers are experiencing frequent control board (PCB) failures, S-bus communication errors, and costly delays in repair services.
Ongoing Issues and Frequent System Failures
Mitsubishi Electric mini-split systems were marketed as durable, high-efficiency climate control solutions for homes and businesses. However, consumers report a disturbing trend: when these systems fail, Mitsubishi Electric has been slow to address the underlying problems. The issues often include:
-
Frequent PCB Failures: Owners are repeatedly replacing both indoor and outdoor control boards, only for the same problems to resurface shortly after.
-
S-Bus Communication Failures: This disrupts the system’s operation by causing a loss of synchronization between the indoor and outdoor units, leading to system malfunctions.
-
Expensive Repairs and Long Downtime: With sourcing replacement parts taking weeks, consumers are left without functional HVAC systems for extended periods, leading to costly repairs.
The Mitsubishi Electric Mini-Split System Design Flaw
Many Mitsubishi mini-split systems, including the GL and MXZ models, suffer from a design flaw that leaves them susceptible to small voltage fluctuations and minor power irregularities. These seemingly insignificant issues can trigger significant system failures. Even after replacing faulty components, the same problems continue to arise, leaving consumers with extended downtimes and high repair costs.
Could You Be Eligible for Compensation?
If you’ve experienced repeated PCB failures, S-bus communication issues, or long delays in repairs, you may be entitled to compensation. Below are some legal avenues that may apply:
-
Design or Manufacturing Defect: The control boards may be too sensitive to normal voltage fluctuations, pointing to potential design or manufacturing flaws.
-
Failure to Warn / Omission: Mitsubishi Electric may have failed to inform consumers about the risk of voltage issues damaging the control boards or the need for surge protection.
-
Breach of Warranty / Unjust Enrichment: If you have paid out-of-pocket for repairs or replacements despite being under warranty, you may have a claim for breach of warranty or unjust enrichment.
-
Equitable Relief: Possible remedies could include part replacements, reimbursement for repair costs, or system redesigns to prevent future failures.
