Hi there! I'm not a professional, but am looking for some professional advice. I've got an electric furnace that is about 15 years old. It's got a two-speed fan. It runs on low all the time and then runs on high when heating is called for. It also has a secondary thermostat located outside that is supposed to turn on an extra two banks of heat when the temperature gets too low. The problem is that sometimes the extra two banks of heat do not turn off. ie. the fan is running on low and is heating the house when it should just be circulating the air. Can anyone give me some advice on this? I'd really appreciate it.
