Dave for Model Number MDB7749awm This dishwasher seems to be having overheating problems. I have replaced the control board twice, and the control panel once. The motor on the soap dispenser was melted and I replaced that assembly. After all of that repair work, only two weeks of a few cleaning cycles, it seems I have blown the thermal fuse at the point where it was either heating the water for the steam cleaning cycle or drying. The interior was warm and there was water still in the bottom, but it appears the dishes were clean when it stopped. The thermal fuse is on order but all recommendations say I should find the source of the over heating including if the vent is opening properly before I install the new thermal fuse.. How do I check the vent- how does it work on this model. I'll look around for shorts but can you recommend any other checks I should perform? Thanks
Answer Hello Dave. It could blow due to wiring. Try replacing with the new harness sent with the part and see if it works properly. Read More... Answered by AppliancePartsPros.com | Thursday, December 12, 2013
