In this blog, you will learn 12 common furnace problems and ways to fix them. Whoa, are you excited to learn these? If yes, let’s directly dive into it.
- The Thermostat is Not Set to ‘Heat.’
We don’t really need HVAC experts to resolve this issue, but we just have to check once: Is your thermostat turned on and set to the correct temperature?
How To Fix
- Even if you’re convinced it is, Go ahead and double-check.
- It’s possible that it was turned off by accident or that the temperature was adjusted too aggressively.
- It’s also conceivable that the batteries in your thermostat have died.
- Your System is Not Receiving Power
If that’s the case, check: Is your Furnace turned on? We know it also sounds absurd, but it’s definitely worth looking at before moving on to other options.
How To Fix
- Check to see whether the circuit breaker has tripped if your furnace is hooked in.
- If the breaker that controls the furnace is turned off, turn it back on.
- If the switch is between ON and OFF, flip it to OFF first.
- Your Furnace is Making Dragging Sound
If your blower is making a gritty or dragging sound, your System’s ball bearings are worn out, and you should switch it off immediately.
How To Fix
Well, you’ll need an expert to do it so that there won’t be any issues.
- Your System is Producing Squealing Sound
Furnaces that squeak suggest a slipping or worn blower belt. You should be able to handle this repair on your own if you’re tech-savvy.
How To Fix
- If there isn’t any visible damage to the belt, tighten it.
- If the belt is showing signs of wear, get a new one from your local home improvement store and replace it according to the instructions in your owner’s manual.
- There are Pilot Issues in Your Furnace
If your older Furnace’s pilot light doesn’t remain lit, you’ll need the assistance of a professional to check various possible issues. It’s possible that you have a faulty thermocouple or a clogged pilot orifice, that your flame setting is too low, or that you have a faulty safety switch. These could be solved at home.
How To Fix
- Turn off the gas supply and wait several minutes before attempting to relight your pilot.
- Your Furnace has Dirty Filters
The importance of cleaning your furnace filters regularly cannot be underestimated. Filters that are clogged restrict airflow, making your furnace work harder. This can cause the heat exchanger to overheat, causing your unit to shut down.
How To Fix
- Air filters should be cleaned regularly.
- Your Furnace Burners are Dirty
If your burners become clogged, they won’t be able to emit enough natural gas to ignite, leaving you without heat. Blue flames indicate a healthy burner; any other color, such as yellow or orange, indicates the presence of trash in the mix.
How To Fix
- Clean the burners regularly.
- Your Furnace is Producing Cracked Heat
Your Furnace’s capacity to do its job is hampered by a fractured heat exchanger, which can allow dangerous carbon monoxide to flow into your home.
How To Fix
- Shut down your Furnace and contact Capital City Comfort’s HVAC professionals right away if you sense your heat exchanger is cracked.
- Your Furnace is Not Blowing Air
You most likely have a broken blower fan belt if your Furnace turns on but doesn’t seem to be pushing air.
How To Fix
- You can change the belt yourself or hire HVAC professionals to do it for you.
- Your Furnace is Having Popping Ducts
Ducts stretch as they heat up and contract as they cool, which explains the majority of the popping and pinging noises you hear. You can possibly have a sagging metal flap inside a duct that wiggles as air passes through.
How To Fix
- If you can pinpoint the sound source, try making a small dent in that spot to see if the sound stops.
- Your Furnace Keeps Turning Off.
Is it like your Furnace is not working properly? Or, is it kept shutting off in between. If that’s the case, it could be because of the following things:
- The furnace filter is not clean.
- The flame sensor is defective.
- The thermostat is not working properly.
How To Fix
- Clean the filters.
- Replace flame sensor and thermostat.
- Your Furnace Producing Bad Odour
