Ever wonder what it looks like on the inside of a clothes dryer? Probably not, otherwise you would have dug up some pictures on the ‘Net by now. Anyway, since you came all this way to my little corner of the web, why not sit a spell and check out what I found when I took my LG DLE2514w dryer apart?
As you can see, there isn’t much to the average clothes dryer once you get the front panel off and remove the large drum that holds the laundry.
On the left you’ll see the motor that both turns the drum and rotates the exhaust fan. The metal box on the right contains the heater core. Bolted on to the side of the heater is a thermostat to shut off the heater if it gets too hot and an emergency fuse that blows at a designated temperature should the thermostat fail to do its job (Which just happened to be the problem that led me to take this thing apart in the first place).
So, there ya go. This is one major appliance that is unworthy of its intimidating looks (Or outrageous repair costs!). The whole thing came apart with a philips-head screwdriver and can be tested with even the crappiest of multimeters.
Testing the thermostat was quite amusing. While it initially looked fine, it turned out that it wasn’t switching off at the right temp. This was tested by throwing it on the stove in a frying pan and monitoring it’s temperature with a meat thermometer to see how hot it would get before breaking the circuit. You can monitor the thermostat to see if the connection is open or closed using a multimeter on its terminals, but mine also switched off with a loud “CLACK!” that caused me to jump out of my skin the first time it happened. Under these conditions, my defective thermostat switched off at about 210 degrees, well above the thermal threshold of 125 degrees listed on the wiring diagram sticker posted inside the dryer.
How much did this repair cost? $15 for the thermostat and $10 for a new fuse (+$10 for the first fuse I bought because the thermostat seemed okay and another $8 for a new multimeter ‘cause I couldn’t find mine until the day after I ordered a new one). I used these guys and got the new parts in about three days. Sears Parts Direct is a great place to check for part numbers and diagrams, but once you have that info, there’s usually a better deal to be found elsewhere.
