Troubleshooting Manual for Typical Furnace Issues


I need to be heated or hot enough.


Various factors could cause your furnace's failure to heal appropriately. This may include everything from a misplaced thermostat to a broken heater. You can turn the dial to increase the heat if the issue is with your thermostat. However, if your furnace is the issue, you must contact a professional to get it inspected or fixed.



Sounding the Squealer


Blower belts sliding or wearing out cause furnaces to emit screeching noises. If you don't detect any damage, the belt may need to be tightened, which is another explanation for the rumbling and squeaking.


Purchase a replacement belt from your neighborhood home improvement store and install it by the owner's manual's instructions if the belt is showing wear and tear symptoms. However, if you want to save time, you may always get your belt tested and replaced by a professional.


Power Isn't Getting To The Furnace


Check whether your thermostat is plugged in correctly and if it is operational and set to the proper temperature. Some typical furnace issues are the result of faulty connections or perhaps no connections at all. Even though it seems ridiculous to think that it may have disconnected itself, it is worth looking into before ruling out any other alternatives.


If your furnace is connected, the circuit breaker may have tripped, leading to other potential issues. If the furnace's breaker is set to "OFF," flip it back to "ON." When forced to choose between ON and OFF, select OFF before turning it back on. If it trips again, you may have a problem with the wiring or the breaker. Furthermore, it would be best if you worked with a licensed electrician as like furnace replacement, Mississauga.


A Grinding or Scraping Noise is Coming from the Furnace


You should stop using your blower immediately if it starts to rub or scrape because the ball bearings are worn out. For this adjustment, you'll require the assistance of a qualified HVAC technician.


Issues with the Pilot Light or Ignition


If your older furnace's pilot light doesn't stay lit, you'll need a professional's help to look into a few possible problems. Your flame setting may be too low, your thermocouple may not function properly, your pilot orifice may be clogged, or your safety switch may be damaged.


Turn off the gas supply and wait a few minutes before attempting to relight your pilot before troubleshooting your furnace. Because natural gas is highly combustible, there could be a dangerous gas buildup around the device if the pilot light has been out for a period.


If your furnace makes utilization of an electric ignitor, it is imperative to inspect the flame sensor. Your furnace's vital safety feature shuts down the entire system when it detects gas but no flames. These sensors cannot "see" the fire when they become dirty, leading to an unintentional system shutdown.



Practical Safety Advice


  • Turn off the furnace's power before tripping the circuit breaker or using the stove.
  • Eliminate the gas supply.
  • Use a screwdriver to carefully remove the flame sensor, a thin metal rod located at the burner assembly.
  • Gently scrub the sensor with fine-grit sandpaper or an emery board.
  • After wiping out any lingering dust with a paper towel, replace the sensor.

smoky burners


If your burners are blocked up with debris and other things, you won't get any heat since they won't be able to release enough natural gas to start combustion. In addition, any different hue, such as yellow or orange, suggests that your burner is unclean, even if blue flames indicate a healthy burner. You can avoid these issues by regularly cleaning and service at furnace replacement in Oakville.


obstructed filters


It is essential to replace your furnace filters regularly. Filters that are clogged up force your furnace to work harder, which might overheat the heat exchanger and cause your appliance to shut off. At best, you'll have an inefficient furnace that uses more energy but generates less heat.


In the worst-case scenario, the lifespan of your furnace will be limited, and your home won't receive enough heat from the stove. If your furnace doesn't give off enough heat or constantly turns on and off, there's a good chance that it's starving for air.


Heat exchanger with cracks or damage


The proper operation of your furnace is hampered by a cracked or damaged heat exchanger, which also opens the door to harmful carbon monoxide leaks in your home. The warning signs of a cracked heat exchanger can be challenging to spot, although they may include the following:


  •  inside your furnace, soot 
  •  noxious odor coming from the furnace
  •  Near the stove, there is water on the ground.


Limit control switch that is broken


If your blower fan runs continuously and you are confident that your thermostat is set to AUTO rather than ON, your limit control switch may be to blame. The controller directly beneath the box sends heat from the furnace to the ducts when the air gets too hot, shutting down the system. Contact a qualified HVAC expert if your limit switch is broken or needs to be replaced. Contact at (905) 334-7885
