Carrier Furnace Heat Exchangers

One of the most important parts of any furnace is the metal heat exchanger. This is a part of the furnace that separates the air stream from the fire and sends air through to the living areas. The carrier furnace heat exchanger is essential for it to produce the heat that is required to keep a house warm and cozy.

If there is a change in the flame color or pattern when the blower starts to operate and it suddenly starts to jump or waver this indicates that there is something wrong with the exchanger. This usually indicates that there is a crack or break and inspecting/ testing is needed. It may even call for a new unit altogether.

When there is a crack or break in the heat exchanger, combustion or carbon monoxide, can get into the air stream and be released in the home. This can cause severe health problems. Often this leaking is very subtle and family members have headaches or generally do not feel well from inhaling the fumes.

The installation of a home carbon monoxide detector should be installed in every home that has a gas furnace. This can usually detect carbon monoxide or other combustion gases, however it is not a guarantee. It depends on the size of the leak or damage if it is to be shown on the detector.

Many things can cause a exchanger leak problem. The most common one is from a crack or rust. When looking for a suspected opening, one should look at welds and seams and a possible crack, which are common points for this problem.

Causes of some cracks or openings could be caused by shipment damage or installation and will be noticed soon after it is installed. Another cause can be because of overheating, which means the furnace was operating beyond the normal temperatures. The latter seldom happens but, if it does, it’s usually from improper installation.

If one has a furnace that has been in operation for a number of years it is important that one keep on the lookout for a possible heat exchange problems. One can rest assured that the Carrier furnace heat exchanger is very carefully inspected when the furnace is manufactured and there have seldom been any problems in this area. In addition, all manufacturing is done with the very best materials available and treated to prevent this kind of problem.

Easy Carrier Furnace Ignitor Replacement

Electronic ignition gas furnaces are the latest development and are much more efficient than the previous models. Three different types available are the electronic, intermittent spark pilot, intermittent hot surface ignition pilot and hot surface ignitors. The one found on the carrier furnace is hot surface, considered a superior type on the market. A carrier furnace ignitor replacement is not difficult when one understands the system and follows a few simple instructions.

The furnace uses this unit to light the gas and also uses a flame sensor which will turn the heat completely off if it cannot detect a flame source. This is what happens when the ignitor is not working correctly. So, if one is having a problem with it not working efficiently this is one of the first things that should be checked.

The power to the furnace should, of course, be completely turned off. This can be done either by the unit switch or by the circuit breaker. In addition, one should turn off the gas valve. This will make the operation of replacing the part danger free.

Opening the front access panel, one will find the ignitor alongside the burner assembly. It is easy to recognize as it is made of ceramic material with wiring. Some other wiring forms a harness and should be pulled apart. There are two screws securing the part to the furnace. These can be easily removed using a Phillips-head screwdriver. With the removal of the screws it is easily detached.

After the ignitor is removed one should go to an authorized Carrier dealer and secure a replacement. Always take the original part to the dealer to be sure the correct substitution is obtained. The dealer can also answer any questions concerning putting the unit back in or why it became defective to start with.

This furnace part is very sensitive to anything touching it, including the hands, so care should be taken in handling it. While it will not interrupt its immediate operation it will cause it to wear out faster than usual. One would then proceed to install it using the same removal steps, in reverse.

After putting back the screws the wiring harness would be rewired to the wire terminal block and the panel door replaced. This is a very simple way of handling a carrier furnace ignitor replacement. When re-installed properly, the unit should take off and immediately start producing the heat needed for a comfortable home.

Easy Carrier Furnace Maintenance

There are two basic ways to perform Carrier furnace maintenance. You can have a professional come out. You may choose to do it yourself.

In difficult economic times, you may not be able to afford professional care. You can at least, do it yourself. Here are things about both situations.

Professional care

It is much easier to call someone out to clean the entire unit. A professional will make sure that everything is cleaned and lubricated. He will also check to see that all parts are in good working order.

This inspection is very important. It is a good reason to pay someone, if you can afford it. You do not want to have a breakdown in the middle of a bitterly cold night. Also, you want to be sure that there are no carbon monoxide leaks.

Doing it yourself

You can get your unit clean and ready for the winter. There are a few basic steps to use. You may need a screwdriver, shop vac, and cleaning rags.

Make sure that you have a new filter too. Be sure that you have turned the power off to the unit. This is usually a separate breaker in the box.

Blower motor

Look for a panel that has the blower motor. Many of them simply pull out. However, you may need to remove screws.

Check the blow motor. Does it have places to oil? If so make sure and carefully place a few drops of oil in the areas. Look to see the recommendation for oil.

You may need non detergent oil. Check with the owner manual or look for any labels on the unit.

Before replacing the blower motor, look to see if you can change the speed. In winter, you can place it on low or medium. A rule of thumb is higher speeds for cooling and lower for heating.

Some blower motors may have belts. If it does, examine it and check for signs of wear and cracks. Put the blower motor back. Put back all panels too.


Clean everything well with the shop vac. Get all dust, dirt and any soot, out of the unit. Take your time to give it a good cleaning. Clean the outside of the unit too. Wipe everything down, when done.


Check the filter. It probably needs to be replaced. This is a pretty straight forward job. However, make sure that it is pointed in the right direction of air flow. This is very important. If it is in the wrong way, it can affect the performance. Your filter should be replaced every month of operation.


After you are done, check your work. Make sure that everything is back in place. Turn the power back on. It is a good idea to run it for a few minutes. You may get a funny smell from the ducts. This is common during the first few hours of operation.


Carrier furnace maintenance can be done in two methods. You can hire a professional. You will be sure that it is properly cleaned and all parts inspected. This may save future headaches and breakdowns.

If money is a problem, you can still clean your unit and prepare it for winter. Kill the power. Pull out the blower motor and see if it needs to be oiled. Most newer ones have sealed bearing and do not require oil.

Change the speed to medium or low, for winter, if possible. Vacuum out everything that you can. Make sure it is very clean. Install a new filter. Be sure it is all back together. Turn the power back on and test it. It may smell funny, the first time that you use it.

Do It Yourself Carrier Furnace Repair

When your bought your Carrier furnace, you may have been under the impression that you would never have to repair it. Even the highest quality furnaces need some repair at one time or another.

The longer you have your furnace, the more likely that it will need to be repaired. With normal wear and tear, a typical Carrier furnace will probably have at least one or two issues within the first 5 years. Here are a few Carrier furnace repairs that you might need to make.

If your furnace won’t stay lit, you might have to replace your flame sensor. Take a look at what is happening when you try to light your pilot light.

If you light up the light and then the furnace does not kick on, then your flame sensor is probably faulty. The job of the flame sensor is to tell the furnace when to turn on and off.

Replacing your flame sensor is not very hard and can usually be done by the home owner.

When everything seems to be working properly with the pilot light, flame and burner, but your furnace blower won’t come on, there might be a problem with the circuit board.

The job of the circuit board is to start up the blower motor at the correct time. If the circuit board has gone bad, then it will need to be replaced. This repair is a little more difficult, so it might be a good idea to call in a certified Carrier repair person.

Problems with your furnace don’t always have to lead to repair work. If your furnace isn’t working properly, you should check to make sure that your air filters are clean and not clogged.

Clogged or dirty air filter can give you a lot of problems with your furnace. If your filter is clogged, simply purchase a new one and replace it. In many cases, this will fix the problem.

If you do need to hire a repair person to come and do some Carrier furnace repairs, make sure that you find one who is qualified and licensed. It’s a good idea to get recommendations from friends and neighbors to find a good repair person before you hire anyone.
