Here are your parts

Here is the wiring diagram, see attachment.

First thing to check is the power. The motor uses half the line (120 volts) while the heating coil requires then full 240 volts.

Try flipping the breaker off/on slowly a couple times, sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Be careful as 240 volts is lethal !!!

Next check the heating coil, should ba about 10 ohms.
The4n check the thermostats and thermal cut-off, all should be 0 ohms.
If the thermal cut-off is blwn there are other things you should check before replacing it.

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.

Unplug the dryer, and take the big back panel off. Then on the right hand side, is the heater housing. It will either be the element, or the thermal fuse. The thermal fuse is located on the top left side of the heater housing. To take the element out if you need. There are two 1/4 inch screws to remove, one on the left of the housing, about 6 inches from the bottom of the housing, and one on the right. Take the wires off the element, and slide in right out.
