I looked it up on the internet. Guys on YouTube suggested that the thermal switch might have been triggered. I checked and tested the thermal fuse, but it was OK. I called a repairman who showed up without so much as a screwdriver in his pockets. He charged me $70 for the service call. He played with the buttons on the dryer (I had also done that) and announced that my dryer was good for the garbage. However, all was not lost because he could have a reconditionned unit delivered to me for $700 that very afternoon. I became suspicious. He then told me that my dryer was made with the cheapest parts available anywhere in the world and that the motor would go next. He was even surprised the belt wasn't a gonner. I sent him on his way. I just wanted him out of my house. I really felt like he was cheating me. With a dead dryer on my hands, I went for broke and opened it. I found the electronic control module. One of the electronic components was charred, clearly blown. I found the part on the internet and ordered it. It arrived 2 days later. I installed it in about 5 minutes, no problem. You can't wire it back wrong, because each connecter is different from the others and only fits in one way: foolproof, unless you can insert a square connector into a round one. I plugged in the dryer and it's working beautifully. just like the day I bought it. Funny thing: we saw the repairman's truck cruising our street a daybreak on the next garbage pick-up day, probably looking for my discarded dryer that he could have loaded up in his truck, repaired and sold for big profit to an unsuspecting customer later down the line. Thank you, AppliancePartsPro.com for your excellent service and helping me fix my dryer. You guys are the best. I should really report that repairman to the Better Business Bureau, or something like that.
