I'm at my wits end. About a month ago, my dryer Samsung DV42H5000EW/A3 stopping working. I'd turn it on, press the start button and the relay on the PCB would click then the dryer just powered off. I tested thermal fuse, door switch, belt cut-off switch, motor windings, the fuses at the heating elements, and everything tested fine. Also, nothing is blocking the vent.
New PCB came ("PCB #1") , but I could tell it was used so I sent it back since it was supposed to be new. However, I put it in and the dryer worked normally. We did about 7 loads and no issues. As stated, I sent it back since it was used and I paid for new. Now PCB #2 arrived. I installed it, powered on the dryer, pressed start button and "click." Back to my original problem. I traced the clicking to one of the relays on the PCB so I boxed it up and sent it back as DOA. PCB #3 arrived today, I installed it, powered on dryer, hit the start button, and it ran normally so I powered it off. My wife put a load in the dryer 5 minutes later, powered it up, hit the start button, the lightbulb in the ceiling dimmed, and then "CLICK" from a relay on the PCB.
I tested everything listed above again fully expecting the motor windings to be shorted given the lights dimmed, but the resistance matches almost exactly what the specs are on the schematic. I am at a loss now as I find it hard to believe that I really got two bad PCBs in a row? Has anyone ever seen anything like this? PLEASE, if you have any suggestions, please reply.
Despite the thermal fuse testing fine, I'm going to replace it anyway as I had something really flakey happen with one of the fuses on the sub-panel for my water heater. Long story short, a fuse on one off the legs was testing fine, yet I didn't have power at the element it was feeding on the water heater. Other than that, I'm at a loss as everything else that I tested above I tested again today and it's all testing good\normal. So either my THIRD PCB just randomly failed, or something else is taking them out but I have no idea what it could be since the motor isn't shorted. Any suggestions would be most appreciated! At this juncture if I can't find the issue, assuming there is one and it's not just my usual "luck", then I'm going to return the PCB for a replacement, sell that new replacement on Ebay and buy a new dryer as I'm out of ideas.
