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.
