A fire engine and an aerial ladder platform from Harrogate, and a further fire engine from Knaresborough were sent.
They tackled a fire in a walk-in type wardrobe within a bedroom in a flat on the second floor.
The fire started in a fridge freezer used within the room, which suffered fire, heat and smoke damage.
Crews wearing breathing apparatus used a hose to extinguish before venting the building using a fan. Further checks were made with a thermal imagining camera.
No persons were involved and the cause is believed to be an electrical fault.
