Causes and Cures for Low Airflow 3. Ignition Source There are two ways in which a furnace ignites the gas air mixture that comes into it. The oldest way is by a pilot light and over the last 30 years or so these have been replaced by electronic ignition systems.
If these fail to do their job your furnace will not come on. Pilot Light This is a small flame which is constantly burning inside your furnace. If you look at the bottom of your furnace you will see a tray where the burners are. Your pilot light is located to one side of this tray just slightly above it usually. If not, you can use a long match to try and carefully light it again.
If that does not work then you have a bigger problem. Electronic Furnace Ignition With an electronic furnace igniter switch, your furnace is safer and does not use the small amount of gas that a furnace with a pilot light does. These igniters are located in about the same position as where we described the pilot light as being.
Look under your furnace and see if your igniter glows when your furnace tries to start up. You will also hear a clicking noise that is a sign your heater system is trying to come on.
Repeated clicking in small intervals usually means your igniter is not coming on and working. The only simply remedy for this that anyone can do is to very gently reach in and clean the igniter and the area around it. This will sometimes get rid of carbon that has built up around some sensitive ignition points and is keeping the system from coming on.
Turn off the furnace before trying to do this step! See the FAQ Section below for igniter cleaning step-by-step directions. Thermostat If you turn your heater on and then move the thermostat to a higher setting several things should happen that will make the furnace ignite. After that, you will hear the swoosh sound of the gas igniting.
After a few seconds, hot air will then flow out of the vents in the rooms of your home. None of this will happen of course if your thermostat is not working properly. All will be silent near your gas furnace unit. Fortunately, you know where to locate your thermostat. Here are the steps we suggest to effectively remove it and install a new thermostat: 1. Buy a new thermostat that will work with your system. It must have the functions you require such as two-stage heat or cooling, etc.
Buying a compatible thermostat is discussed in detail in our thermostat buying guide. Follow exact instructions for thermostat replacement. We strongly suggest you take a picture of the wiring connections, so that the new thermostat can be wired exactly the same — heating wire to heating connection, AC to AC, etc.
Draft Issues Your furnace has a motor called a draft motor or draft inducer motor or blower. Check the filter, of course, and replace a dirty filter.
The next best step might be to contact an HVAC company using the number on this page to have the situation evaluated. However, if you enjoy DIY, find the high limit switch. Many look like a small, round disc with two wires attached on the inside of the furnace.
Next, unfasten the switch, and gently pull it out. Look for the pin between the wires. Push the pin to close the switch, and turn the power to the furnace off for a few minutes to reset the error code.
Then power the furnace again, and see if the furnace comes on. If you know how to check for that with a multimeter, you can troubleshoot this little device.
They have the experience and equipment to pinpoint most heater problems in just a matter of minutes. Here is a word of caution though that you really need to pay attention too.

This will keep you from getting any big surprises when they give you the furnace repair bill. This estimate filters out unqualified contractors and busy companies that will overcharge you. Tips On How Not to Be Left Out in the Cold with Your Furnace The most common time to have your furnace fail to ignite is the first time you go to use it after it has not been used in a while.
If you are turning it on it probably means it got pretty cold outside and now you have no heat. There are some things you can do to avoid this scenario and to keep your furnaces ignition in tip-top working order. Most people know when the cold season in their area is.
Schedule a routine maintenance furnace check once a year. Again the best time to do this is a month before your areas cold season hits. During this routine maintenance session, your HVAC service person will check over the entire system to make sure it's running OK and clean critical furnace ignition parts.
Many times they will catch small problems too and repair them before they become much bigger and more expensive furnace repairs. Can you be more specific about how to clean a furnace igniter? Also, is that the same thing as a hot surface igniter? First, yes, the igniter is commonly called a hot surface igniter or even a glow plug. Cleaning your hot surface igniter requires a small screwdriver and fine-grit sandpaper made for metal.
Turn off power to the furnace. Take off the furnace door, and locate the igniter. Remove the two screws holding it in place, and gently pull it out with or without detaching the wires.
Oil from your hands will burn extra hot and might damage the igniter when it lights. Gently sand all sides until the soot has been removed. Re-install and secure it. If you can clean it, you can replace it. I have a multimeter. Can I test the igniter? Yes, you can. Great idea, in fact. This furnace troubleshooting step will help you rule out whether the igniter is the cause of the gas furnace not igniting or starting.
Perhaps if you already own a multimeter, you know how to test an igniter. The essential steps are to: Check if the igniter is getting power. While the igniter is connected, turn the furnace to On. When the inducer motor comes on, use the leads on the meter, one on each igniter connection.
If it shows about volts, there is power to the igniter. Check the resistance of the igniter. Switch the meter to Ohms. Good igniters typically read in the 40 to ohms range, or perhaps up to If it reads higher, consider it bad and replace it. It tells you where to find a new igniter and how to replace it. What are they, and could they help me solve an ignition problem?
Some codes definitely relate to furnace ignition problems. These error codes include a bad flame sensor or an electric ignition module. Take the cover off your furnace and look for one or two lights. Near the lights or on the inside of the cover, there should be a key showing you what the flash codes mean. Pro Tip: Try to get a new furnace filter in the next hours to prevent a lot of dust from coating the blower and other internal parts.
If those items get really dusty, use a shop vacuum with a brush head to gently remove the dust. Remove the filter or filters, turn off power to the furnace, and then turn it back on.
This resets the furnace. Then, turn up your thermostat past the room temperature, and see if the furnace fires up.
8 Things to Do When Your Furnace Ignitor Isn’t Igniting
Banging Noise When the Furnace Kicks On Common causes of banging noises include: Dirty furnace burners: Does it take several several seconds to a minute before the furnace comes on after you call for heat? This is a delayed ignition caused by dirty furnace burners. The dirt keeps the burners from igniting the gas, so the gas builds up.
Once the gas ignites it makes the loud banging noise. These small explosions can crack the heat exchanger, which is expensive to repair. If you hear this noise, turn off your furnace immediately to prevent any further damage to the furnace and call a professional for furnace repair.
A few blower wheel problems include: Blower wheel is loose from the motor wheel. Get a professional to tighten the wheel. The blower wheel is broken and needs replacing.
The motor mount broke, causing the whole blower assembly to drop and hit the housing. This noise is usually caused by: A loose, slipping, or fraying blower belt. Shaft bearings that need oil. Add lightweight oil to the lubrication port at each end of the shaft. A malfunctioning blower motor. This needs to be fixed or replaced by a professional.
