Julie for Model Number MGDE300VW0 Sorry for repeat question entered question before I finished. Dryer takes longer to dry cloths. No error code is produced. Took off lower panel and dryer heater assembly appears to be functioning properly. Measured temperatures at the exhaust outlet and got the following: Low 107 (F), Med 112 (F), High 118 (F). The table show shut off temp higher (125,140,155). Ran dryer empty on high setting for 15 minutes and it never reached the design cut off temp of 155 so the the heater never turned off.
Answer Julie, the exhaust thermistor WP8577274 would need to be tested for resistance and it should measure between 8.5 to 10.5 K Ohms at around 80°F. If the exhaust thermistor tests good, the wire harness would need to be inspected for any broke or loose sections. If the main harness W10111011 checks ok, the most likely failure would be the main control WPW10174745. Read More... Answered by AppliancePartsPros.com | Tuesday, December 5, 2023
