Original problem was that our dryer stopped heating.
So I took the dryer apart and notice the heating coil was all rusted so I decided to replace the coil and also bought a thermal limiter in case that was the issue. I think it would have been better to buy the entire heating assembly kit as you don't have to worry about stretching the coil correctly as you engage it into the clips. So I installed the new coil and put the dryer back together. Plugged it in and still no heat. Then I happened to notice that the a wire was disconnected near the top of the dryer close to a black plastic housing... A quick trip to Walmart to buy some electrical connectors and crimpers and then its started heating perfectly!
Lesson learned - check all wiring before buying parts! At least I know the heating coil should be good for a while. Also I didn't know how long it would take for the heating coil to get hot. After it started working it took less than 15 seconds to start glowing red hot. Good fyi.
