Two recent residential fires were caused by electrical appliance malfunctions, Honolulu Fire Department investigations have concluded.

A fire at 790 Kaipii St. in Kailua on Dec. 16 was caused by a malfunction in a video game console battery charger, fire Capt. Terry Seelig said. The fire spread throughout the house from a cabinet in a living room in the rear of the home, causing $400,000 in damage, he said.

A malfunctioning hand-held electric massager is to blame for a fire Wednesday at 434 Launiu St. in Waikiki, Seelig said. That fire spread through the bottom-floor unit into a rental unit on the second floor, causing about $450,000 in damage, he said.

Seelig said consumers should regularly clean and inspect electrical appliances for signs of deterioration or damage.
