ALWAYS REMEMBER to unplug your dryer before attempting any repair!!!!!

Got this for a 10 year old dryer that powered on and tumbled ok but stopped heating up and quit drying clothes.  I thought it was either the fuse or the element. If you have a meter handy you can easily check your old fuse for continuity and if you don't get any reading then you have a bad fuse or you can disconnect the old fuse and electrical tape the two wires that are connected to the fuse together and if the dryer begins to work properly then you know it's a bad fuse. You could actually run your dryer like this without the fuse, but running it like this is not recommended. mainly because it's a fire hazard and your appliance could catch on fire.

once you have the fuse replaced and mounted and both the two wires connected.... Make sure all lint traps are cleaned and all lint and debris are removed so there isn't any thing clogging up the pathway's so the lint and air can freely exit you dryer. This has to be done or else your new fuse will most likely blow again very soon.
hope this helps? good luck!
