Fire caused significant damage to a house in the 1300 block of Western Plains Drive Tuesday morning.

Firefighters responded around 11:50 am and found that the fire had burned out after using up all of the oxygen in the home. The fire appears to have started several hours earlier.

No one was home at the time of the fire, which was reported when a family member returned to the house.

Investigators determined the likely cause was an electrical malfunction in the refrigerator.

Firefighters removed large amounts of carbon monoxide from inside the home and made sure no smoldering fire remained. Six on-duty and ten recalled firefighters responded to the call.
