Here are your parts
Replacement parts for General Electric DVLR223ET0WW Electric dryer | AppliancePartsPros.comCould be you have a grounded element.
The element sags/breaks and touches the frame, it then runs all the time and the thermostats cannot regulate it.
Unplug the unit.
Remove the wires from the heating elements.
Be sure to mark them so you know where they go.
Measure each element, usually around 10 to15 ohms.
Then measure from each connector to the frame/case, should be infinite ohms (open)
If not you have a grounded element.
If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.
There is a good STICKY at the start of this forum about it's use.
