Here are your parts
Replacement parts for Roper RED4340SQ1 29" ELECTRIC DRYER | AppliancePartsPros.com

There is a sticky at the start of this section on how to check parts and it has info on meter use.

Also here is my little blurb on using a meter.

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.
4. When you start always short the meter leads together. This will tell you that the meter is working and if there is any 0 offset.

Start with the heater itself. They are usually in the 8 to 12 ohm range.

If you find that the thermal cut-off (Item 6 in Section 1) has blown, then get back to us as there are other things you should check before replacing it.

Since you are a noob to meter usage I hesitate to include the following so if you do this be extremely careful. The meter should be set to AC volts usually the 750 volt scale.
Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
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.
Do this with the heater off and on.

You are welcome.

And thanks for getting back to us. Now when others search for a similar problem they will see what actually worked instead of just suggestions about what could be the cause.

Also glad to hear that you made some brownie points, they sure make life more enjoyable.
