What to Do When Your Heating System Won’t Turn On In Nashville, TN

When the temperatures drop in Nashville, TN, there is nothing worse than discovering that your heating system won’t turn on. The sudden realization that your home might stay chilly can be both frustrating and worrisome. However, before you panic, there are several steps you can take to troubleshoot and possibly resolve the issue. In this guide, we will walk you through some potential reasons your heater is not working and offer some simple fixes. And, if these steps do not work, the professionals at Frog Heating, Air, Electrical, & Plumbing offer expert heating system repairs in Nashville, TN.

Check the Thermostat

It may seem obvious, but one of the most common reasons a heater will not turn on is a simple thermostat issue. Make sure the thermostat is set to “heat,” and the temperature is set higher than the current indoor temperature. If your thermostat is battery-powered, check the batteries. Sometimes, weak or dead batteries can cause a thermostat to malfunction. Replace them with fresh ones and see if your heater starts working.

Also, ensure that your thermostat is functioning properly. If the display is blank or unresponsive, it might be faulty or disconnected from the power source. In this case, resetting or replacing the thermostat may resolve the issue. If you are unsure, the experts at Frog Heating, Air, Electrical, & Plumbing can help diagnose and fix thermostat issues in Nashville, TN, and the surrounding areas.

Check the Power Supply

A heater that does not turn on could be due to a power issue. First, check your circuit breaker to ensure that the breaker for your heating system has not tripped. If the breaker has tripped, reset it by flipping it off and then back on. However, if the breaker continues to trip, there could be an electrical issue, which is best handled by a professional technician.

Also, if you have an electric furnace, check to see if there is a dedicated switch that controls the heater. This switch is often located near the furnace or air handler and looks like a standard light switch. Ensure that it’s in the “on” position.

Check the Pilot Light (for Gas Furnaces)

If you have a gas furnace and it will not engage, the problem could be with the pilot light. Many older gas furnaces have a pilot light that ignites the burners. If the pilot light has gone out, your furnace will not be able to generate heat. You can try to relight the pilot light according to the manufacturer’s instructions.

However, if the pilot light does not stay lit or you smell gas, turn off your gas supply immediately and contact the professionals. Gas leaks are dangerous and should be handled by licensed technicians like those at Frog Heating, Air, Electrical, & Plumbing, who can safely repair the issue.

Inspect the Air Filter

A dirty air filter can also prevent your heater from turning on. If the filter is clogged, it restricts airflow, which can cause your furnace to overheat and shut down as a safety precaution. Check your air filter, and, if it is dirty, replace it with a new one. Most air filters should be changed every 1-3 months, depending on usage and the type of filter.

After replacing the air filter, reset your furnace by turning off the power, waiting a few minutes, and then turning it back on. If this solves the issue, be sure to change your filters regularly to help prevent future problems.

Look for Blocked Vents or Registers

Blocked or closed vents can cause issues with your heater. Make sure all the vents and registers in your home are open and unblocked by furniture or other objects. When airflow is restricted, your heating system has to work harder, which can lead to overheating or failure to operate.
