Daikin Comfort Technologies Manufacturing has recalled about 4,633 Amana-brand through-the-wall air conditioners and heat pumps after finding that a circuit inside the units can shoot flames if it short-circuits. The U.S. Consumer Product Safety Commission opened the case as a fast-track recall on September 3, 2026, a designation used when a manufacturer moves quickly to address a hazard once it has been confirmed. Amana is best known to shoppers as a household appliance brand, but the recalled units are wall-mounted commercial systems most often installed in hotel rooms, apartment buildings and other multi-unit properties rather than single-family homes.
Inside the Snubber Circuit That Can Arc
Engineers add a snubber circuit to absorb voltage spikes that occur when an electrical switch or relay opens and closes, protecting nearby components from arcing damage. It is normally one of the more mundane parts of a control board, doing its job quietly every time the unit cycles on or off. In these units, CPSC says that same circuit can itself short internally, and when it does, it can emit flames rather than simply failing safely, turning a protective component into the ignition source instead of a barrier against one.
Daikin Comfort Technologies Manufacturing, known within the industry as DCT, has received two reports of a component on the control board shorting in this way. No injuries have been reported in either case, and the company has not disclosed whether the shorting occurred during normal operation, at startup, or under some other specific condition, only that the control-board component was involved both times.
Five Model Numbers, One Recalled Family
The recall covers five model numbers, all beginning with the letters PB: PBC092J00AA, PBC093J00AA, PBC122J00AA and PBC123J00AA are air conditioners, while PBH092J12AA is a heat pump. The model and serial number are printed on a white sticker on the front edge of the unit’s base pan, low enough on the housing that it can be easy to miss during a routine inspection without knowing exactly where to look. All five belong to Amana’s Through the Wall, or TTW, packaged product line rather than the window or split-system units more commonly sold for residential use, which means most homeowners will not encounter one of these models directly.
Built for Hotels and Apartment Buildings, Not Homes
The recalled units were sold through direct sales and distribution customers nationwide from April 2025 through June 2026, priced between $625 and $900, and installed most often at hotels, apartment buildings and commercial properties looking to replace aging through-the-wall climate control. That sales channel is the reason the recall reads differently from a typical home-appliance notice: rather than reaching individual consumers directly, DCT is relying heavily on the contractors, property managers and distributors who originally specified and installed the units to pass the recall along to building owners and tenants.
About 126 additional units were sold in Canada as part of a parallel recall, underscoring how much of this product line moves through commercial contractors rather than retail stores on either side of the border.
A Pattern of Fire Recalls in Amana’s Commercial Lineup
This is not the first time Daikin Comfort Technologies has recalled Amana-branded commercial climate-control equipment over a fire risk. CPSC’s own recall records list a 2023 recall of Amana packaged terminal air conditioners and heat pumps over burn and fire hazards, a 2024 recall of Amana, Daikin and Goodman-branded packaged air conditioning and heat pump units over a separate fire hazard, and a distinct 2026 recall covering other Amana units whose heating element can stay energized during a ground fault even after the unit is switched off. None of those earlier cases involved the snubber-circuit defect behind this recall, but together they show a manufacturer whose commercial-grade wall and packaged units have drawn repeated fire-hazard scrutiny across several product generations rather than a single isolated design.
Two Shorting Reports Behind a Fast-Track Recall
CPSC’s fast-track process lets a company report a hazard and negotiate a recall’s terms with the agency in a matter of weeks rather than the months a standard investigation can take, provided the manufacturer moves to correct the problem voluntarily. That two confirmed shorting incidents were enough to trigger a fast-track recall covering thousands of units, rather than a smaller-scale service bulletin, reflects how seriously CPSC treats any fire-hazard finding tied to a component meant to prevent exactly that outcome.
Cutting the Cord to Get a Refund
Consumers are being told to stop using the recalled units immediately and contact DCT to request a full refund rather than a repaired replacement. The process requires owners to provide their contact information, physically cut the unit’s power cord, and upload a photo of both the serial number and the severed cord before the refund is issued — a step meant to keep a flame-risk unit from being resold or reinstalled elsewhere once it has been pulled from service. DCT can be reached toll-free at 833-730-0939 from 8 a.m. to 5 p.m. Central time, Monday through Friday, or through the refund request page the company has set up for this recall. Full details, including the base-pan label photos, appear in the recall notice published by the Consumer Product Safety Commission.
