GE Gas Dryer only runs when 'Start Knob' is held.
 
I just picked up a used GE Gas Dryer (DBSR453GB1WW) off craigslist.

It only runs when the 'Start Knob' is held to the right, as soon as you let go it shuts off. It tumbles fine, and gets hot. I've contacted the seller and they offered to just give me back my money but I figured if it's a few dollars to fix it I'll ask them to just pay for the repair/part.

With some quick googling it looks like it is either. The start switch http://www.appliancepartspros.com/Ap...ap4980910.aspx or the motor http://www.appliancepartspros.com/Ap...ap4295548.aspx I don't really understand how it could be the motor, but I have zero experience in dryer repair so I'm not going to question strangers on the Internet, so I came here for the opinions of some more strangers.

Any help is greatly appreciated. Thanks!

I would check the door switch.

It won't go at all if the door is open, regardless of if I hold the start knob or not, could it still have something to do with the door switch?

DexterII 08-12-2012 06:26 PM

Probably not. I was a bit doubtful on that suggestion myself, since it would run with the dial turned, but it's a relatively common and inexpensive fix, so figured it was worth a shot. Doesn't sound like that is the case though.

Sounds like the motor May not be switching from the start to run windings. Typically if the motor doesn't run nothing will. You can confirm by checking motor current draw and ensuring the unit is switching.

Just to confirm, the unit will only run when the start switch is held?

That is exactly what happens. Do you think the motor would be a DIY replacement or should an experienced tech do that?

Looks like the motor would be as much if not more than what I paid for the dryer...Could it just be a loose wire on the motor or is it the motor itself is just bad?

Ximerian 08-13-2012 01:44 PM

Replaced the rotary start switch and the same problem still exists...is there anything else it could be other than the motor?

hardwareman 08-13-2012 05:22 PM

probably not the motor, is there a wiring diagram on the dryer and if so can you upload it here?

Ximerian 08-13-2012 05:50 PM

There is a diagram. I don't have access to a scanner until tomorrow.

EDIT: Found the diagram online for that model dryer. http://media.fotki.com/1_p,sggkrfrdg...4017img-or.jpg

If you look at the diagram, there is a "motor switch" which is integral to the motor. It is an internal, centrifugal switch which takes over when the motor spins. See if the motor is covered with lint and clean it out if possible. This switch is necessary for the machine to operate after you let go of the start switch.

hardwareman 08-13-2012 09:58 PM

did you check all the wires on the motor to see if one came loose

Jacques 08-14-2012 06:06 AM

Belt sw not in ckt will do that too.

Check both idler spring sw and centrifugal sw on the motor. Those are in series with eachother and could both be the issue.

You can ohm or continuity check the idler spring sw and if that is ok you should be able to check the centrifugal sw by checking current draw of the motor. Motor should draw higher current to begin and go down to a lower number (typically around 2-3 amps).

Missouri Bound 08-14-2012 10:32 PM

I do not think it would run if the idler switch was open..holding the start switch would not override it. (IMO)

Jacques 08-15-2012 07:04 AM

It would do exactly what you describe=mimic bad motor cent sw.
