First ran the built-in diagnostic tests. Got error code indicating that the inlet thermistor was open. Removed lower access panel and did continuity checks on the inlet thermistor, thermal cutoff and heating element. Even doing these checks is very difficult on this model due to the location of these parts and the limited access through the so-called access panel. But was able to get an open reading on the heating element, so I knew that at least that part was faulty. Could not get a reliable reading on the thermistor or the thermal cutoff due to their location. After reviewing the video for replacing the heating element, it was pretty clear I was going to have to pretty much completely disassemble the dryer to get to the heating element, so I ordered the heating element and the thermal cutoff kit (includes the inlet thermistor and the thermal cutoff), just in case they were bad and had caused the heating element to fail. The video supplied by Appliance Parts Pros was very helpful, although there were a couple of steps that didn't quite match my model. The most difficult part of this repair for my model was figuring out how to get the front panel/bulkhead assembly removed so I could get to the heater assembly. Once I got that apart and had the drum removed, replacement of the heating element and the thermal cutoff components was trivial. As at least one other reviewer noted, the most difficult part of the reassembly for a single person is reinstalling the drum - you might want to enlist a second person to support the weight of the drum while you position the front bulkhead, which has the rollers that the drum must rest on, underneath the front edge of the drum. I did it myself, but it is not easy. This repair takes a bit of time and, although I have to confess to uttering more than one cuss word due to the idiotic design choices on this model, one of the benefits of having to remove everything to get to the heating element was that I was able to give the inside of the dryer a good thorough cleaning. This was the original heating element in this dryer and it had lasted 11 years. A lot of lint and dog hair had accumulated inside the dryer in those 11 years. By the way, don't put too much faith in the error codes you get from the built-in diagnostics - turns out that once I could get clear access to the thermistor and thermal cutoff to run continuity checks, they tested good. But I replaced them anyway and set the originals aside as spares.
