Samsung Dryer DV219AEW/XAA - Diagnostic test / service manual needed

[girlnextdoor]

Hello all,

The nuts and bolts:  Looking for how to enter test mode on a Samsung DV219AEW/XAA. Can't find it on the web.  There are no error codes showing at the moment, but although it lets you input a cycle (and lights up as if it is starting) there is no heat, the drum doesn't spin, and after counting down two minute into the cycle, the timer drops down to 1 minute.  I need the entry method to start the diagnostic test, and the error code table, which I know is only in the service manual, but I'm not qualified to be an appliance tech so I can't sign up for a membership. Any assistance is greatly appreciated.

The long version:  Sometime lurker, this is my first post. Since I may be here more often, I'll go ahead and introduce myself. I'm the wife of a supposed-to-be-retired electrician who is also a do-anything kind of guy. He grew up in the trades and was on job sites since he was around 8 years old, so he's got a lot of experience and, as we privately like to call it, "little known facts of useless information" in his head. Though, of course, they aren't useless at all - he can figure out just about anything. (I'm not bragging - trust me he has his flaws, as do I, LOL- but he really is a very, very talented handy guy, as well as a kick butt electrician.)

Although he is primarily an electrician, he is often asked to do other things, and appliance repair comes up relatively often. Usually it's after he's on site for something else, and the customer says, "Hey, I also have xxxx, do you know anything about working on that?"  I am what we jokingly call tech support. I scour the web for diagnostic tests, service manuals, and any other info I can find. I've logged countless hours on the web on various electrical and appliance forums looking up problems, solutions, printing out schematics, etc.  (You'd be surprised at the level of detail involved with old electrical panels, for example.) With appliances, from research I'm usually able to narrow the problems down, and predict parts needed, though not always, because sometimes it's wiring issues and of course he needs to do that on site. In any case, I'm his right hand on stuff. It's my job to get him the info he needs to start diagnosing, or go one better and point him in the most likely direction, saving him some time. In some cases we do tell the customer to call an actual appliance repair tech, and in rare cases, to not bother repairing, and to buy a replacement.

I'm not in a position to do the coursework here,  but I love the concept and execution of this site. If my husband were younger, I'm sure he would do the courses, since he already has the electrical knowledge as well as general "how things work" knowledge...but he's actually supposed to be retired, LOL.

go to goggle..type the model number, go to the bottom of the listings....Search Related, I found the listing with Samsung diagnostic plus Youtube videos....also check the  "People also ask" section.....Good for some evening reading/viewing..

These dryer don't have an error code retrieval/diagnostic test mode. They display error codes in real time. You may have a bad motor or the control board may not be sending voltage to the motor. The control board seems to think the dryer is running, is not sensing moisture from the moisture sensor bars and shutting down the cycle. I'm looking at either of these being the points of interest because the motor has a centrifugal switch on it that will close when the motor is physically running that supplies the other half of the power to the heating element, so either the motor is bad or the control is not sending power to the motor. I don't think it's a broken belt because there is a motor interlock switch that shuts the motor down when the belt breaks and the display does nothing. There is no error code for these failures. The error codes that do get displayed are few and are usually for open or shorted thermistors.

This is almost certainly the idler pulley/belt switch being open caused by broken belt, broken idler pulley or belt slipped off the pulley. Very easy to check, just take the top off and see if belt is broken(or if absent, it's lying on the underside of the drum) or loose.

Much much more likely than a bad motor or centrifugal switch. 

With the drum not turning on normal mode, the moisture sensor isn't coming in contact with wet clothes.
