you'll need a meter to check out some of the parts.first with a meter go to the back of the dryer,find the cord and follow it to where it connects to the dryer,make sure you have 240 volts there,if so unplug it,go to the front of dryer and remove the bottom panel,pull out the lint filter and remove the duct that the lint filter slides down into,check to make sure the belt isn't broke,there's a switch that will kill the power if the belt is broke,also open the door and push in on the door switch,if it doesn't click the switch is bad,if all this checks ok check the thermal fuse,when you removed the duct you'll see the blower wheel,the fuse is on top of the blower wheel housing and to the right,it's a white plastic piece around an inch long,pull at least one of the wires off and check it with the meter,if this is bad you have to clean out the dryer and the vent line,vac out the duct and cabinet and if the vent line is long remove it from the back of dryer and blow it out with a leaf blower,if that's good check the thermal cutoff on the heater box,you always have to pull at least one wire off to check it,if you don't find any one of these parts bad you could have a bad computer board but most likely it will be one of the parts i mentioned.go here and you can see the parts,check part 59,42,47 and 48 but first check to make sure you have 240 volts,check the door switch and belt first,hope this helps
