1. The power supply

Electricity is a must for the furnace to work even when it comes to gas furnaces. Each and every furnace has a switch that has to be on. Ensure that you look carefully, find it and ensure it has been switched on. In most cases, it may be turned off accidentally by a maintenance technician or when cleaning the utility room. It could also be a child in your house who turns the switch off when playing. Before panicking, it is therefore advisable that you confirm that the switch is always on.

2. The Thermostat

A thermostat is very important in the working of your furnace. Most of the modern thermostats normally have batteries in them. Ensure that the batteries are there and if so, replace them and turn your device back on. This could be the only issue affecting the working of your furnace and can be resolved within minutes.

3. The Filter

Furnaces are designed in such a way that they have a safety feature to automatically turn them off when they get too hot. A furnace can become too hot as a result of a dirty filter. A dirty furnace prevents air from circulating freely and cooling the device as it should. This makes it too hot and the safety feature automatically turns it off to protect your home. You can clean the filter or just simply replace it and the furnace will be okay.
