When I wrote about the heater element going out on an electric clothes dryer, I was focused on the fact that the element would fail without notice. In talking to a friend, he offered the thought that most people would probably start a drying cycle and walk away, not noticing the longer drying time. Good point.
Since most clothes dryers have an automated sensor cycle to determine dryness – I would be curious as to how many people used a timed vs. an auto sensing cycle – the failed element could go for some time without notice. It’s probably a little like a hot water heater where one element fails, and the hot water diminishes sooner than expected. You can see in the picture to the left (click to enlarge) how one element in the dryer broke and the other remained intact; note the cracked insulator.
After performing the repair (I chose to use the restring kit vs. a new element assembly – more labor, less cost), I spent some time thinking about the overall operation of a clothes dryer and the installation of this unit. It’s in a hallway, behind a set of bi-fold doors; it shares space with the washing machine. Unlike a laundry room, this could be considered an alcove or closet installation. When I looked at the airflow diagram, it was interesting to see the draw from the rear, passing ‘hot’ air over the clothes – the air passes over the heater element into the drum – then exits by the lint filter. There is a small fan to push/draw the hot air out the vent.
That’s when it hit me. If our bi-folds were closed, you could be limiting the natural airflow required for efficiency, and potentially diminish the service life. Looking closer at the installation manual, for an alcove or closet install, I came across the following: “Closet doors must be louvered or otherwise ventilated and must contain a minimum of 60 sq. in. of open area equally distributed. If the closet contains both a washer and a dryer, doors must contain a minimum of 120 sq. in. of open area equally distributed.” This appears to apply to both electric and gas dryers. Also, check your model’s installation manual for more specific information in this regard.
Since we run our dryer with the doors open, which are not louvered, it’s not a problem. But, I was left wondering how many installations happen without taking note of this requirement. More so, I came across a ‘handyman’ use tip that encouraged people to close doors during the summer, and open them in the winter; the idea behind the tip was for more efficient heating and cooling in the house as a result of the hot air surrounding the dryer. After reading the installation manual, that’s probably not a good idea, especially if the installation was like ours with solid bi-fold doors in an alcove.
One other interesting note in the installation manual was, “If your dryer is approved for installation in an alcove or closet, it will be stated on a label on the dryer back.” In all the times I have purchased major appliances, I can’t recall my being asked about the installation at the time of purchase.
Being proactive with a recent refrigerator install, by measuring the space first, I found that some newer models and styles would not have fit our older cabinet space. That simple step saved me from the grief of a great looking refrigerator that wouldn’t fit the space. Like many purchases, it pays to read the installation and use manual, first. In the case of the clothes dryer, it would be a good idea to check the labels, too.
