What Should I Do If My Furnace Doesn’t Start Working

A furnace can face various problems during the winter season. However, as the owner, you should not panic and contact your HVAC company for furnace repair in Garden Grove without reading this article first.

If your furnace is not working when you switch it on, there can be various reasons behind it. Sometimes, it can be a minor issue, for which call your technician is a waste of time and money. However, here are some components of a furnace that you can check before you give up fixing your furnace and contact your technician:

Circuit Breaker

The circuit breaker ensures that the furnace does not receive too much high voltage while working. When the voltage increases, the circuit breaker trips to break the connection and protect the furnace components from damage.

If your furnace is not starting, it could be possible that the connection somehow broke. First, you should check the furnace circuit breaker to ensure that the electricity supply is intact. If the breaker tripped, switch it back on to resume the supply. You can also replace it easily if the circuit breaker is too old to work.


A thermostat detects your home’s temperature and signals the furnace to work accordingly. Most of the homes in Garden Grove have intelligent thermostats that understand the temperature preference of the owners and remind them of maintenance schedules. In addition, you can contact your HVAC company that provides heating service in Garden Grove, CA, to get a smart thermostat for your home.

If your current thermostat often malfunctions, it can cause the furnace not to work efficiently. Either your furnace will not switch on, or it will not maintain the required temperature. First, check its batteries and wiring connections to ensure the thermostat is working efficiently.

Air Filters

Air filters have an essential role in the working of your furnace. They have many functions that affect your family members’ furnace efficiency and health. Clean air filters ensure that the system airflow is smooth and catch foreign matter like bacteria, viruses, dust, dirt, allergens, pollen, and pet hair to maintain the indoor air quality of your home. 

However, if the air filters remain dirty for a long time, the system will work for more hours, increasing energy bills each month. Moreover, your family members may face increased allergies and breathing problems. Therefore, ensure to clean and replace your air filters regularly for an efficient working system.

Pilot Light

A malfunctioning pilot light is one of the significant reasons why furnace owners contact their HVAC companies for heating repair in Garden Grove. However, contacting your technician immediately once you realize your pilot light is why your furnace is not working is unnecessary.

You can easily reset your pilot light. First, press the off button and wait for a few minutes. Then, switch on the button and hold the reset button while using a lighter to ignite the pilot light and release the reset button. This simple process can help you save your technician time and money.

Blower Motor

The only purpose of a blower motor is to push out the warm air from the furnace to the vents. An efficient blower motor takes reasonable time to circulate the warm air throughout the house using the vents and ducts.

If the blower motor is dirty or is facing any technical issue, the warm air will not reach your home and rooms. Your furnace may be working efficiently by creating enough warm air for your home, but if the blower motor does not work, the warm air will remain in the furnace and not circulate.

Ignition Switch

The ignition switch of a furnace burns the gas that enters your furnace. Its small role affects the whole working of your furnace. If the ignition switch does not detect the gas and light it, your furnace will not generate heat, and your home will remain cold.

Various signs indicate that your ignition switch is malfunctioning, like cold air coming out from the vents and frequent short cycling of the system. Clean the ignition switch regularly to ensure that it works efficiently.

You should ensure to check all the above signs before contacting your technician. However, if your furnace does not start working even after checking these components, it may indicate that it is facing a significant issue that needs immediate professional attention.
