After pulling the top off of the dryer, I could see that one of the heating coils was shorting against the drum. After pulling the front panel and drum I discovered that a couple of the standoffs had crumbled away allowing the coil to contact the drum/case. Just to be safe I decided to replace the entire heating assembly. There are four screws and a handful of wires to remove. I tested each of the thermostats/safeties for continuity and they all tested good. I received the replacement part in two days. Shipping cost was very reasonable. Very nice experience with appliancepartspros. Their website is awesome, easy to navigate with many good tips, and fast. They are my new goto source for parts and information . I am a 100% disabled veteran and was able to quickly and easily get my wife's dryer up and running again before she even had time to complain.
