POULSBO — A couple nearly lost their home after a cabinet on the second floor of their house burst into flames.

Poulsbo Fire crews responded to the house fire around 2 p.m. Jan. 12 at the intersection of Mosjon Circle and Stavanger Loop near the Forest Rock neighborhood.

Fire and emergency medical crews from Bainbridge Island, Central Kitsap Fire & Rescue, North Kitsap Fire & Rescue and Subase Bangor fire departments and the Poulsbo Police Department also responded.

PFD Deputy Fire Marshal Jerry Cooper said the fire was caused by a blocked heat register that overheated. A cabinet that was blocking the heat register was filled with plastic items and tupperware and caught fire, he said.

One of the residents, who was home at the time, said she heard “crackling” in the wall, Cooper explained, but couldn’t figure out what it was. The cabinet then burst into flames, he said.

The heating unit on the second floor was made by Cadet Manufacturers, which put a recall on this particular system about 15 years ago, Cooper said. While the owners, who have lived in the house for four years, did not know it was that particular heater, the blockage and not the recalled system was what caused the fire, Cooper added.

The second floor was the main living area, with three bedrooms, two bathrooms, a living room, dining room and kitchen. Cooper estimated $250,000 in damages to the house and noted that the entire second floor will have to be rebuilt.

“The heat and smoke damage is extensive,” he said.

Neither the resident nor firefighters were injured.

Another large structure fire in Suquamish also had NKF&R and PFD crews busy early Monday afternoon.

Firefighters arrived on the scene to find smoke coming from the eaves of a two-story building on Harris Avenue with flames breaching a second floor entry door.

The house was being used for storage and a woodworking shop. The building owner told firefighters he had been working in the shop that morning, but had gone next door to eat lunch.

The Kitsap County Fire Marshal’s Office investigator believes the fire started in an extension cord that was used to power a band saw earlier in the day.

The cord appeared to have been wedged under the open entry door, damaging its insulation.
