Furnace or Thermostat Issues

Categories: Heating

My furnace is not turning off. The temp is kept at around 68-70. Two days ago, I woke up to 82 degrees due to the furnace not stopping, thermostat was set to 68. I shut the heat off from the thermostat and reset it. Yesterday, I replaced the batteries. This evening, I turned on the heat and it kick off and continued to run up to 7 degrees, even when the thermostat was set at 68. Again I set the thermostat to off and reset it. This was not an issue back in early October, when we go some cold days, the furnace/thermostat was running ok for about 1-2 weeks. Any ideas? or Technician recommendations?
