Visit the Circuit Breaker
Are you interested in getting your broken furnace working correctly without delay? Sometimes, all it takes is checking your circuit breaker. Your furnace operates only when receiving power. A tripped circuit prevents energy from reaching the furnace.
Note that even a gas or oil furnace often uses some energy from the electric company in standard operation, so we recommend checking the power switch regardless of what kind of heating system you use. Open the front panel and ensure the circuit breaker for your furnace is in the “on” position.
Some property owners tape their circuit breakers to keep the switch “on.” While this may seem like an easy solution, it does not stop the circuit from tripping. Tape makes it harder to see if the circuit breaker tripped.
Check the Thermostat for Your Heating System
If your furnace turns on but doesn’t provide you with your desired temperature, we recommend that you check your thermostat. Make sure the following points apply to your thermostat:
Has Working Batteries
Your thermostat uses electricity in part but often relies on battery power. Weak batteries often prevent the thermostat from communicating with your furnace. Replace your batteries to see if that fixes the issue.
Shows the Temperature You Want
HVAC professionals recommend that you check the current temperature for your furnace before getting into any more in-depth troubleshooting. Sometimes, other people in your home change the temperature without telling you, leading to cold air when you want to bump up the furnace.
Does Not Have the Fan On
Some property owners believe that leaving the fan running all the time helps with furnace function. But leaving your fan on often leads to cooler air throughout your property. The furnace stops generating heat when it detects the correct temperatures in your home.
However, if you have the fan on, the furnace continues to blow. Because it is no longer heating the air, you feel cool air moving through your vent system.
Most homeowners find checking the thermostat to be an easy fix to common furnace problems. Double-check that no one changed the thermostat without your permission, and see if the furnace begins heating your home in the following minutes.
Fuel Up a Gas Furnace
Do you have a gas furnace? If so, we recommend that you check your natural gas supply. You can get a professional to ensure that the gas line connects to your furnace correctly and that the gas valve delivers the fuel properly.
Gas furnaces work only if the gas gets to the combustion chamber through the gas valves. Clogs that prevent the flow of gas stop your furnace from working. Cracks also cause problems.
In many cases, property owners fail to notice a crack in their furnace right away. However, if you smell gas, it could indicate that you have a leak. Contact an HVAC technician in this situation to get professional help. Natural gas leaks endanger your health and well-being.
Change Your Air Filter
Your HVAC system uses an air filter to get rid of contaminants:
- Pet hair
Air filters remove these pieces of debris from your air ducts. Eventually, your furnace filter fills up and gets clogged if you do not change the filter regularly. Clogged filters reduce the efficiency of your heat pump at first. Eventually, your furnace will not function properly. Address this issue by changing the filter and enjoying the warm air from your furnace.
Check the Pilot Light
Gas furnaces use a pilot light. Other appliances – like gas stoves – also use these lights. Your furnace pilot light may go out if people make repairs and forget to relight it or if an unexpected burst of air blows it out.
Speak with a professional HVAC technician about relighting your pilot light in cold weather. The experts often step in to help homeowners with a light that won’t stay lit. Modern furnaces often have better-protected pilot lights, preventing this issue.
Contact a Furnace Repair Professional
We have reviewed easy fixes to issues with your heating system. Going through the troubleshooting steps described above may get your heat system working correctly again. However, you have options if your furnace remains out of operation after you perform these tasks:
- Change the thermostat
- Check the circuit breaker
- Light the pilot light
- Add fuel to the furnace
If your system turns on, the furnace should start raising the temperature quickly. If not, consider reaching out to an HVAC repair company for help. Crews take care of furnace repair quickly, getting your heating system operational again with essential repairs:
Furnace Flame Sensor
The flame sensor (or ignition sensor) serves as a safety feature in your furnace. It makes sure that the gas ignites properly in the furnace and stops additional gas from entering the furnace if something goes wrong. These sensors play a vital role in preventing a fire.
A dirty sensor often fails to detect the ignition properly. Technicians clean this ignition sensor when performing furnace maintenance, preventing this problem.
Power Disconnect Switch
Though power disconnect switches generally are not seen in residential properties, some businesses have power disconnect switches. These switches allow you to shut down power quickly. Using them resembles flipping a large light switch. Sometimes, these switches get turned off accidentally, leading to a loss of energy in your furnace.
The heat exchanger in your furnace transmits warmth to the air before it circulates through your property. Over time, the exchanger may crack due to repeatedly overheating or just normal wear and tear.
In some cases, the furnace continues to operate with a cracked heat exchanger. However, damage to an exchanger allows dangerous gases to escape into surrounding areas. For this reason, we recommend that you replace a cracked exchanger as quickly as possible.
