We had a storm, and the power flashed to the house. It was only off a few seconds, then everything was normal. I felt the temperature rising in the house, and checked the thermostat. It was blank, so I replaced the batteries and still nothing. It is a Hunter programmable about 11 years old. Any help?

Check the furnace and A/C fuses and circuit breakers. The check the transformer that supplies 24 volts to the thermostat. The transformer might have gone out during the storm.
