MDG5500AWW - when the door is closed, the drum is spinning.
« on: October 20, 2011, 07:52:32 PM »
Here is the whole story: About a year and a half ago a power surge fried the main board on my Maytag dryer.  I purchased a new one from a local appliance parts dealer and installed it.  Everything works fine EXCEPT for the fact that when the door is closed, regardless of what the control panel says, the drum is spinning.  I assumed, I now know incorrectly, that there was a hard to find relay or something that was fused and that once I found and fixed/replaced it all would be good.  Well, I finally took the dryer apart to find there is no such relay.  Did I get a crappy control board?  Could it be another part in the unit?  If it is the control board I am not going to get another one.  Do you think I could swap out some parts (motor relay) from the old one (which I kept)?  The technical part doesn't worry me..I am wicked handy....just want to make sure I am replacing the correct parts.

Unplug the dryer and unplug the plug to connector BB1 on the control.  Check for continuity between the terminals on connector BB1.  If there is continuity, the relay is stuck and the board is bad. Schematic

thank you for the prompt reply.  So, yes, the terminals at BB1 have continuity between them.   That means that I bought a crap board...but I have had it long enough that I can' take it back.  The old board has no continuity.  Is this just a matter of a bad relay?  If so can I not just unsolder the relay from the old board and instal it on the new(er) board?

Sure, it's definitely worth a try.  Let us know how it turns out.

So I was wrong.  I took the new(er) board out today and before I swapped out components I ran a meter over the bb1 terminals.  I no longer had continuity.  Apparently I hadn't completely disconnected the board last night when I checked it on the machine.  Any thoughts now?
