Heater Won’t Turn On? Here Are Four Reasons It May Be Happening

While summers may be hot, the winters in Lake Forest, CA can get pretty cold. If you wake up one morning to find that your heating system won’t turn on, call a technician right away so that they can get to the bottom of it.    There are many reasons why a heating system may fail to turn on. Sometimes the issue lies in the fuel connection, such as a tripped circuit. In other cases it has to do with damaged parts or an accessory component like a thermostat.    No matter what the issue is, a qualified HVAC specialist will be able to find the root of the problem and the best course of action to fix it.    Take a look at four reasons why your heating system may not be turning on: 
  • Cracked Heat Exchanger

If you own a gas or propane-fueled furnace, technicians always check the heat exchanger during heater maintenance appointments. The heat exchanger is responsible for transferring heat from one spot to another. A heat exchanger expands and contracts as it heats and cools. This causes wear on the part and may cause cracks over time. While a cracked heat exchanger may not seem like a big deal, it can cause many problems.   If a heat exchanger is damaged enough, it may cause your system to fail. This is because the system cannot receive proper airflow and heat with a cracked heat exchanger. If it continues to run with this damage, eventually it will fail from inefficiency and overwork.    A cracked heat exchanger can also cause major safety issues. Carbon monoxide can leak from a damaged heat exchanger. If allowed to leak for long enough, it can cause carbon monoxide poisoning. This is why it is highly recommended to install a carbon monoxide detector right next to your furnace so that you are notified as soon as a leak begins.    If you believe your heat exchanger is damaged, call your heating specialist right away so that they can assess the situation and help you find a solution.
  • Damaged Starting Components

There are a few different starting components that you may find in your heating system:  
  • Pilot light: if you have a gas furnace, you most likely have burners that keep the system hot. The pilot light is essentially the ignition flame for the burner. 
  • Start capacitor: many furnaces and heating systems come with a start capacitor. This part provides an extra burst of energy to get the blowers and fans moving. Once it has started the system, it provides constant energy to keep the other parts moving.
  • Fuel connection: whether your heating system is gas, electric or propane, it has to be connected to its fuel source. If you have an electric heating system then your fuel connection may be the breaker box. A gas furnace, on the other hand, will have a connection to a gas supply.
  All of these parts help to start your system. If one of them fails or becomes damaged, it can cause your system not to start. For many of these starting components, you should be able to repair or replace the part so that your system is back up and running. If you notice that your system isn’t working, give your heating technician a call so that they can diagnose and fix the problem. 
  • Poor Maintenance

If your heating system has not been given proper maintenance in a few years, then it may begin to develop issues. During a maintenance appointment, a technician may replace the filter, clean the burners, check fuel connections, tighten nuts and bolts and lubricate moving parts. All of these tasks are essential to the efficient functioning of a heating system.    Even though many of these tasks seem insignificant to the overall efficiency of the system, they make a huge impact. For example, a blocked air filter can cause your system to work harder to produce the same amount of heat. This can cause your system to overheat and eventually fail.    When your heating system is able to efficiently work through proper maintenance, it can stay in great shape. If your heater is not turning on, the issue may lie with the essential tasks that are performed during a maintenance appointment. Give your technician a call as soon as you notice that your heating system will not start.
  • Thermostat

While this may seem like a no-brainer, it’s important to check your thermostat if your heating system is not turning on. Sometimes the issue is as simple as not setting your thermostat to “warm” or turning it to “on” or “auto”. This is especially true if you live somewhere like Lake Forest, that can be warm during the day and cold at night. It’s easy to forget to turn the heat back on at night.   The case could also be that the thermostat is broken or decalibrated. This may mean that your thermostat is not communicating with your heating system and telling it to turn on. Be sure to contact your heating specialist if you think that the thermostat may be the problem. A technician will be able to calibrate the thermostat or offer great replacement options.
