RELATED: If You Bought This From Walmart, Stop Using it Immediately, Authorities Warn. On Dec. 22, the Consumer Product Safety Commission (CPSC) issued a recall of about 33,570 Royal Sovereign portable air conditioners. Several product models are affected, including PAC-3012, PAC-3012 RB, ARP-3012, ARP-3012 KIT, ARP-3012S, ARP-3014, and ARP-3014 SC. Customers can locate the model number printed on the nameplate sticker located on the back of the appliances. According to the CPSC’s notice, the recall was issued when it was discovered that a “faulty drain motor in the air conditioners can ignite the plastic enclosure of the unit, posing fire and burn hazards to consumers and risk of serious injury or death.” Unfortunately, there have been 11 reports of the units catching fire or smoking, resulting in over $1 million in property damage and two injuries. Tragically, one death was also reported as the result of smoke inhalation after one of the portable air conditioners caught fire.
