DIY at home appliance maintenance , save yourself money and improve the performance of your appliances
Hello and welcome to my DIY appliance maintenance articles. I see so many appliances that break down and have unnecessary repairs due to a filthy machine, and extremely worn out parts. This can easily be remedied by doing a one hour cleaning every other year or so. I would suggest splitting up your appliances and do a couple of them at a time, do these the first year and then the next year do the other set then you can go back to the first set the third year, and so on.
For this demonstration I will be using a Kenmore Elite dryer, this machine is harder to work on and you might need to address your capabilities to do this yourself. Care needs to be taken too insure that you don't fry the electrical control board or panel, if you don't know what this means contact a professional like myself. If you haven't unplugged the machine yet, do so now, the last thing you need is to be shocked. This machine uses a variety of nut drivers ranging from 1/4 to 3/8th. Pull the dryer forward away from the wall, unplug electrical and disconnect exhaust vent. Remove screws along top of lid at rear of machine. The lid will then slide back and up off the machine. Take lower cover off of machine by tipping the machine up and towards the back to see two screws on bottom front. Remove screws and allow the cover to drop out and pull forward. Now go back to top and you will see a cover assembly on one side of dryer this is the control board, carefully remove screws and tip over taking care to watch wires and unhooking any snap-in wire ties.
Make sure you unplug the door switch, and note the wires positions for reassembly, take the remaining screws out of front door cover top and bottom, remove front door. Once you have the front off the machine off, the drum can be removed. Depending on the model you have in your home the belt needs to be loosened. Reach your arms into the spaces below the drum and feel for the belt, follow this to the idler puller gear. Push or pull the puller gear to the side and unhook the belt. Now the tub can be pulled towards the front of the machine and off of the rear rollers, take note of the padding in the tracks by making sure that it stays in place during removal and at the time of reinstallation. Take a good look at the belt, rotate it around the drum and look for fraying on sides or delaminating between the layers both are signs of wear and should be replaced. You will see a lot of dust and some lint, go thru and vacuum up what you can reach. Take a look at the idler pulley
and check to see if any grooves have been worn into the wheel, if so replace it. See pics below to see what you will be looking at in your machine.
In this machine I decided to remove motor and blower fan assembly, it allowed us to clean better. As you can see it was really dirty and by cleaning it, this will help the efficiency of the machine, pay close attention to lint trap and duct leading up to blower fan, check condition of fan and the padding that seals it up. Also check the heat element coils in the heat duct, check to see if any lint is trapped near it, that could possibly be a fire hazard, clean area. Check your coils for broken sections or loose hanging sections, this is a bad element, replace. I would suggest not to run the machine with covers are off, could cause element to overheat due to lack of air flow over coils. If you lucky you will find a mound of change in the machine too to make it all worth the while!!
