Tip & How-To about Dryers
If you are having dryer problems and you cannot even get the thing to start, then you might want to start going through this check list of possibilities. There are a number of things that can cause your dryer to not run.
A couple of the most common problems are the thermal fuse has blown or the door switch is not operating properly. On many dryers if the thermal fuse blows, the dryer will not run at all. This fuse can be checked with an ohm meter. It should show continuity if it is okay. If there is no continuity then you need to replace it and also find out what else failed. This is a safety device that usually blows because something else allowed the dryer to get too hot. It is usually located in the back of the dryer, on the blower housing. Some are oval in shape and others are rectangular, usually with two wires attached.
A defective door switch or a bent door switch lever can also cause you to have problems. If the lever is broken or bent it will not activate the switch. If the switch is broken, this also will not allow the dryer to be started.
The push (or turn) to start switch can go bad, but is unlikely. To check this, hold it in or turn it and then check to make sure you have continuity with an ohm meter.
If the dryer starts and then stops when the switch is released check the control board or the “even heat” control on some model dryers. Some dryers have a belt break switch that can fail or your belt may be way loose or broken.
Check for burn marks or burnt wires at the terminal block on your dryer, poor connections can cause all kinds of problems. Also poor connections can cause fires.
A bad power cord also falls into this same category.
Of course, always check that you have the proper voltage to the outlet that you are plugging into.
