Jay for Model Number WED7800XW0 The dryer runs properly but does not heat. I've seen the L2 error code a couple of times but not consistent. My Exhaust Thermistor is measuring 12900 ohms. Is this within tolerance? Other info: in using the dryer's tech sheet, I've trouble shooted thru. The element, Inlet Thermistor, Thermal Cut-off and Thermal Fuse all have continuity (0 ohms). The diagnosis was to replace the Machine Control Board. I did that with no results. Thanks for your help! JM
