Power Or Gas If your system refuses to operate, chances are it isn’t getting the power it needs. See to it that you have plugged in your units. Even if you remember doing so, it would be ideal that you still verify this. Sometimes a pet or by someone walking past the wires can dislodge it without realizing. Circuit breakers sometimes tend to shut down immediately as a safety measure. If you can’t see anything that could be an emergency you may try turning it on. If it stops working again then immediately call an electrician to look into this. Sometimes when people move from warmer places, they aren’t used to furnaces. Some don’t realize that they need to use a gas company for it to work. Unless your heater uses electricity then this should be something you should examine. Make sure your gas lines are in good condition and haven’t turned off.
