My dryer is not heating so I check out your web site and love the info. I check the heating element and the other common threat and the only one that did not check out was thermal cut off switch # 3977393 but it not sold separate so I had to order the kit #AP3094244. The kit come with the correct thermal cut off switch and a high limit thermostat switch #3390291 with two prongs. The high limit thermostat in my machine is 4 prongs # 3387134 what do I do with the other two prongs the purple wires. Can I even use this high limit thermostat at all. I think it is different heat level than I have.
Thanks for the help and I love web site very helpful.

Hi Nathan,
The thermostat with the part# 3387134 is the cycling thermostat which is located on the blower housing (#8 at the [B]diagram[/B]. The high limit thermostat is located on the burner box (#15 at the [URL="http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5136482&diagram_id=29241158)).
