Remember, even the blower can’t blow away the fact that you forgot to replace the air filter.

Blower Components

The ‘Blower Components’ are the key parts for a furnace’s airflow. Necessary for consistent warmth in the home. Blower Motor, Fan Blade, Belt & Pulley work together to draw in cool air, warm it up, and push it back out. Malfunctioning of these components may lead to the system shutting down, or worse, becoming unreliable.

It is important to ensure regular checks and maintenance of this area. Having a professional maintenance call can save you money – not to mention hassle – in the long run. On the other hand, overlooking blower component issues can result in bigger problems later on.

It is hard to think of a time before blower components heating systems. They have been in use in houses since the industrial revolution changes when coal and wood-burning stoves were no longer viable options. Looks like the burner needs some commitment – on-again, off-again won’t do for your furnace.

Burner Assembly

The Combustion System is the part that ignites the fuel in your furnace. Let’s take a look at the Burner Assembly, which is made up of several important pieces. It includes burners, nozzles, electrodes, and sensors.

BurnersLet a fuel/air mixture combust
NozzlesRegulate the fuel flow
ElectrodesSpark the ignition
SensorsDetect combustion issues and regulate oxygen

Keep these parts clean and maintained. Blockages can form due to dirt or debris. Regular cleaning and inspections can prevent malfunctions.

Remember to get an annual maintenance check from an HVAC technician for optimal furnace performance.

Don’t light a candle – light a pilot! But make sure it’s off when you’re done or you might start a fire!

Pilot Light

The small flame that ignites the gas burner is a key part of furnaces. It heats the air that goes through ducts and keeps your home warm. Without it, the furnace won’t work.

If your furnace isn’t working properly, check the pilot light. If there’s no flame or it’s a faint blue, there may be a problem. Causes include clogs in the gas line, a malfunctioning thermocouple, or drafts blowing it out.

Also, consider the pilot light’s age. It usually lasts four to ten years. After that, it starts to break down and can cause poor performance or malfunctions.

Pro Tip: If the issues with your furnace’s pilot light continue after cleaning or adjusting, call an HVAC technician. Your furnace may sound like a ball is rolling around inside. That’s probably just worn-out bearings – time for a Furr-ness overhaul!

Ball Bearings

Precision bearings, also known as ball bearings, are used in furnaces. They help the blower motor run smoothly. Without precision bearings, the furnace could be noisy and vibrate.

A table is here with info about issues related to precision bearings.

IssuePotential CauseSolution
NoiseWorn or damaged bearingReplace bearing
VibrationMisaligned or loose bearingAdjust or tighten the bearing
Reduced efficiencyA dirty or clogged filterClean or replace the filter

Be careful when dealing with precision bearings. Don’t touch the surface of the bearing as it may get damaged.

You should take care of precision bearings before they cause bigger problems. Regular maintenance and filter replacements can make them last longer. Don’t wait for it to get worse.

Why did the capacitor break up with the furnace? It said their relationship was just too charged.


An Electrical Energy Storage Unit is a key part of a furnace system. It controls the voltage and makes the furnace work smoothly.

We made a Table to help explain:

StartElectrolyticGives energy to the motor so it can run
RunFilmStores energy for when the furnace is running

Sometimes it can overheat due to too much use, or malfunction in different voltage. Tip: Regularly maintaining this part of the furnace saves money and makes it work better. The high-limit switch of your furnace is like a bouncer. It checks if it’s too hot and shuts off before things get bad.

High Limit Switch

The High Limit Sensor is the safety switch that shuts off the furnace when it gets too hot. When the temperature is too high, this switch detects it and signals for the furnace to shut down. This stops the system from getting too hot and being damaged.

Problems can occur due to faulty wiring, age, or location. It can be installed incorrectly, leading to frequent switches off. Or, airflows may be blocked, making the part misread the temperatures.

I recall a heater repair job where the customer’s furnace wouldn’t switch on. Turns out, the High Limit Sensor had been tripped due to dust and debris in its circuitry. So, we cleaned the equipment and helped with the proper installation to ward off future problems. Looks like this control board’s temper is as unpredictable as a teen’s!
