If Your Heating System Isn’t Working

Tripped Circuit Breaker

If your heating system is not working, first check and make sure your circuit breakers and service switch are on and the thermostat is in heating mode.

It is that time of year again and you are either about to turn on your furnace for the first time in a while or you will in the upcoming weeks. If your furnace does not immediately turn on, there are a couple things you can look for before calling Carey & Walsh, inc.

  • First go to your thermostat and check to make sure that your thermostat is set to “HEAT”. Even though you are raising the temperature on the thermostat, it will not send the signal to the furnace unless it is in the “HEATING MODE”.
  • If you have a high efficiency furnace with a white PVC intake/outtake on the side of your home, check to make sure that either pipe is not clogged with leaves or other debris.  If it is clogged, it could shut the furnace down on a safety.
  • Check your circuit panel for a “Tripped” breaker, if the furnace breaker switch is half way in between the on and the off position, the breaker is tripped. First push the breaker to the off position and then back to the on position. If the breaker repeatedly “Trips”, call us. There may be a more serious issue that needs professional attention.
  • Make sure your furnace switch is in the “ON” position. The switch looks like a light switch that may be on the wall as you enter your basement or mechanical room or possibly directly on your furnace. This switch is often turned off accidentally. If the switch is ON, try resetting the furnace by turning the switch “OFF” for at least 20 seconds, then back on.
