Have you heard of a furnace sequencer before? A furnace sequencer is used in HVAC systems to turn on and off electrical loads in a predetermined sequence. It is responsible for carrying out the equipment operation, from the power switch to when the equipment is completely shut down and all residual power has been removed from the core.
The idea is to utilize outside air for proper HVAC operation, reduce energy consumption, and decrease carbon emissions. The problem with these devices is that they can fail without warning and cause the system to stop functioning. If this happens, you need to understand why it failed and how to fix it.
How Does a Furnace Sequencer Work
The air that passes through your furnace and into a home’s ventilation system is heated by heating elements. These are long, coiled electrical conductors made of metal or resistance wire that heat up quickly and burn out easily. They produce heat and distribute it through the house’s HVAC system.
A central electrical furnace will have fans and heating elements. These take up a lot of energy. So, each sequencer triggers one individual element at a time. The sequencer is like a switchboard for the fireplace and ensures that it does not burn out or overload. They keep furnaces running healthily by staggering power on each heating element, allowing them to operate at low energy consumption levels.
Signs of Malfunctioning Furnace Sequencer
Malfunctioning furnace sequencers can cause several furnace problems, including fluctuating temperatures and faulty heating systems. But what happens when the furnace sequencer malfunctions? We listed some of the most common symptoms of a failing furnace sequencer.
House is not warm as it should be
The sequencer is hidden with the wiring leading up to the heating coils. So, you cannot see, hear, or smell it when things are working correctly. However, it will no longer turn on your heating coils when it goes bad. So, if you notice it is not making the house as warm as it should, the sequencer may not be letting the furnace turn on all the way.
Tripping circuit breaker
The sequencer can fail to coordinate the electrical current flowing through the relays. That will lead to too much voltage going through. When this happens, the circuit breaker in your home will trip and disconnect power from your furnace. Resetting your circuit breaker and calling a furnace repair service are great ways to ensure you continue to have heating.
How to Deal With a Broken Furnace Sequencer
Knowing the signs that indicate malfunctions is important. Thus, saving you both money and time. Solutions to any furnace sequencer problems include replacing the sequencer. If you are experienced with heater service, this is a relatively cheap and simple process. Otherwise, the most efficient way to deal with a broken furnace is to call in furnace servicing. HVAC maintenance technicians are trained to fix common issues like the ones described above. They can look at your system and tell you what repairs your furnace needs so that it runs smoothly again.
