Whirlpool Dryer won't start

make sure door is closed and then if that doesnt do it, open door and look for where the door contacts at closing you will see a little metal table that is like a ground sometimes when a dryer door is closed or slammed the tab might get pulled backwards with the opening of the door again adjust the tab again so contact with door when shut makes contact if that doesnt do it, check your breaker and see if the breaker was tripped too

Always disconnect power before attempting any service. Most electric dryers require 240 volts to operate properly.
You may have only 120 volts to supply the dryer which will give you your symptoms. Click dryer circuit breaker off then back on to reset 240 volt system.Still no heat/run

First, check to see if you have 240v going to the dryer. If one of the breakers is thrown, the dryer won't start.

Reset your dryer breaker just in case it may have tripped. If it did trip inspect your dryer receptacle. If that is fine and you have power, open the door and look carefully for the tiny lever that actuates the door switch. See if it clicks. If the lever is loose missing or no click I would say the switch is bad. If the door switch is fine I would next check the skinny white fuse on the blower housing for continuity. If open the dryer will not run. If the fuse is bad you gonna need to yank off the filter chute and clean it out. If the fuse is good the next thing to check would be the start button. Beyond that you would need to provide a model number because all whirlpool dryers are not made the same.

Dear Sir:
See this possible causes:
Power from the house
see for possible blown fuse or c. breaker tripped. change or reset
Door switch
defective switch, will not start the dryer. test for open see the video
Thermal fuse
test for open or faulty fuse
Wiring
test for burn or breaker wires, measure continuity.
God bless you

Same problem with my Whirlpool Dryer: Model LER4634EZ2 which stopped heating. I checked the coils that was "OK" then I checked the fuse that was "OK" I replaced the Thermal Fuse and High Limit Thermostat then after starting the dryer the heat came on ... problem solved NO.... the dryer just kept running and running until I opened the dryer door. Not going to put 70 or so $$$ into this 10 year old dryer which up until 12/15/2011 worked fine.

Check the door switch by listening for an audible click just as the door opens or closes. If you do not hear an audible click then the door switch is bad. IIf you hear this audible click then go to your circuit breaker box and check to see if they have tripped. If the circuit breakers have tripped reset them ONCE and try the dryer. If the breaker trips again DO NOT reset it. You have an internal short in your dryer and it will require further service.

I would start by checking to make sure the circuit breakers are not tripped. An electric dryer runs on 220 and will have a double circuit breaker - a gas dryer runs off of 110 and will usually not have a dedicated breaker. Once you have determined the power is on, the next most likely problem is the door switch. This prevents the dryer from being activated with the door open. You can "jiggle" the switch while attempting to start the dryer, or check the continuity with an ohmmeter.

Sounds to me like a thermal fuse. The link gives you multiple scenarios and you can even order replacement parts. I have used it myself with success on washers and dryers. Good luck!

I'd check door switch first. Improper voltage, thermal fuse, start switch, motor, and wiring are also possibilities.
