A window air conditioner can catch fire when its motor control board fails

Inside certain Friedrich KÜHL window air conditioners, the control board that runs the fan motor can fail and set the motor on fire. The Consumer Product Safety Commission announced the recall on September 17, 2026, as recall number 26-776, and the agency counts about 2,000 units.

The units are small in number but expensive for the category: CPSC lists retail prices from $1,300 to $2,000, and the models were sold between January and August 2026. Friedrich, the San Antonio importer, has since narrowed the affected population further by motor part number and build dates, which is why the model list alone does not tell an owner whether a given unit is recalled.

The motor control board and the two ignitions

CPSC’s recall notice places the fault in the control board inside the motor. When that board fails, the motor can ignite, and the notice classes the problem as a fire and burn hazard. The same page reports two incidents of motor ignition, one of which produced smoke and fire damage to a home.

The recall also appears in the commission’s recalls feed, dated the same day. That listing is the shortest statement of the defect: a control board inside the motor that can fail and cause fire and burn hazards. Nothing in either document describes a gradual warning sign such as a burning smell before the board fails, so the notice gives owners nothing to watch for beyond checking whether their unit is on the list.

Six KÜHL Q and S models and the motors inside them

Six model numbers are covered: KCVQ08B10A, KHVQ10B11A, KCVS08B10A, KCVS12B10A, KCVS12B30A and KCVS16B30A. Friedrich Air Conditioning Co., based in San Antonio, Texas, is the importer, and the units were built in Mexico. CPSC names PC Richard & Son, Grainger and Johnson Supply among the retailers, along with other appliance dealers nationwide.

Not every unit with those model numbers is in scope. On its own recall page, the company limits the action to KÜHL Q and KÜHL S units fitted with motor 1000581 or 1000582 and built between January 28 and March 27, 2026. Owners are told to open the front white panel, read the model number and serial number from the rating plate inside, and check the serial against the ranges Friedrich lists. The gap between that narrow build window and the January-to-August sales period on the CPSC page means units made in roughly two months were still reaching buyers well into the summer, and a unit bought in August could carry a January or February build date.

Refund or replacement, and the one number to call

Friedrich’s page says most affected units are replaced, while owners of the KHVQ10B11A model receive a refund; CPSC’s summary describes the remedy as a refund or a replacement unit. Anyone whose serial number falls inside the ranges can reach Friedrich at 800-541-6645, from 8 a.m. to 5 p.m. Central time on weekdays, or through the recall page at friedrich.com/product-recall. The two documents differ slightly in how they state the remedy, so the quickest way to settle which applies to a particular unit is the model number on the rating plate, which decides whether the KHVQ10B11A refund path or the replacement path is the one on offer.

The model-by-model detail matters because Friedrich’s page treats the recall as a parts problem as much as a product one. Motors 1000581 and 1000582 are the components named, and the control board inside them is what the company says may fail, posing a fire risk. A KÜHL unit built outside the January 28 to March 27 window, or fitted with a different motor, falls outside the action even when its model number matches one of the six on the list.

Earlier air conditioner fires in CPSC’s files

Motor-driven cooling equipment has produced fire recalls before, and the sizes of those cases show how small this one is, and how differently each ended up on CPSC’s recall list. In December 2021 Royal Sovereign recalled about 33,570 portable units after a faulty drain motor could ignite the plastic enclosure; that notice counted 11 fire or smoking incidents, more than $1 million in property damage and one death from smoke inhalation.

Friedrich itself appears in the archive. A July 2004 recall covered about 26,400 packaged terminal air conditioners whose rotary dial switch could rest between fan speeds and overheat the unit. Friedrich had received 60 overheating reports by then, including nine fires that damaged property, and a resident of a nursing home had suffered smoke inhalation in one of them. The remedy then was an on-site repair scheduled through the company, a different arrangement from the replacement-or-refund approach used now.

The 2004 notice also carried a different instruction from today’s: Friedrich told owners of those packaged units to stop operating them in heating mode until a repair was done. No comparable instruction appears in the 2026 notice.

The 2026 action rests on far thinner numbers, two ignitions across roughly 2,000 units, and the manufacturing dates on Friedrich’s own page cover a window of only about two months, from January 28 to March 27, 2026.
