I just changed the motor, it was what GE says to use, all wiring color coded and connectors the same as I took out.  The new motor works great you put the coins in and it runs perfect.  This is a model  DCCD330GD3WC .

The problem. If you open the door, the unit stops as it is supposed to do.  With the door open the burner and motor are both off (correct).  But if you close the door, the motor is still off (correct, it turns back on after you press the "start button" on the control panel),  But the burner turns back on within a minute while this door is closed (without pushing the start button), the motor, drum, fan are not on.  This is very Dangerous.                   

I am guessing I might have damaged something else in the motor change.  My guess it is a short, bad control board or maybe the timer in the coin slot housing.  BTW, I did a continuity check on the door and belt safety switches, both good.  Also went through all connections and wiggled to insure they making contact.

Any ideas on how to trouble shoot this issue?

Thanks in advance for any help.

Hello,

This is really very dangerous as you mentioned. Did you install a new ge motor part # WE17X10010?
It sounds like there is a wire wrong on the motor switch.. it seems this motor has an updated wiring harness to the switch but yeah this should definitely never happen.. I would think it is related to the motor install and not some other issue unless it happened before the motor was changed.

Hi,

Thanks so much for responding.  So sorry about the late response.  The alert email from the forum went into my spam (don;t check it often).

I am pretty confident the motor came from WE17X10010 which is a kit of motor, shaft drive wheels and connectors.  I purchased this a few years ago for another machine, but didn't use it.  Pictures attached of the old motor (see the bearing swollen up) and the new part # I took after installed.  Both Motors and output wiring's, colors and connector were identical (plug from the machine fit exactly the same) to what I took out. 

I had GE guy come to diagnose.  He first said the flame detector or maybe the count down timer or the main electronic board.  Of course, he said had 4 more calls and didn't have time to open up the machine.  Would not quote a repair because he thought parts would be obsolete.  I said I already replaced the flame detector a few years ago, along with new valves and few other things.  Then said he didn't believe it to be that because they are very reliable.  Then thinking more he thought it could be the push button switch or the coin unit countdown timer.  Since I have two units he suggesting swapping one from the other to troubleshoot.  I will soon when time allows.  This guy didn't want to deal with repair and just listed it as a cancelled no charge call.

I light of the above.  What do you think?

Thanks,

Well sometimes repair people just want to do the easy ones they know for sure.. in and out and a quick charge to the customer.. sounds like he isnt sure. I am hesitant to offer my opinions because i personally would tear the machine down and have my own observations and thoughts while inspecting everything. I had my own commercial washers and dryers too but I have been out of the repair filed for 12 years now and am not as good as I once was "Quoting the Toby Keith song" Smile  I still think this issue could only happen with a motor and or motor switch not wired up correctly or a contact burned on the switch.. this could possibly happen in the same manner with a burnt or stuck contact in the timer but in all my years of repair I have seen this only a small handful of times and it seemed to me in most cases it was a motor or motor switch issue.

Thanks for the reply, review and advise.  Your experience is extremely valuable.  I'll keep you posted, but it will be awhile as I am snowballed on some other issues at the moment.  Thanks again.

Just swapped both the main push button switch and coin count down timer from an identical machine.  No change in results,  I think the next step might be to put my old motor with failing bearings in and see if my issue is with the motor I put in.  Kind of a time consuming job just to do it again regardless of the cause.  Any other suggestions short of this?

Thanks for any help.

just looking back at this post.. the issue started after you changed the motor so to me that is always a red flag.. could be coincidence but  i still think it is related to the motor change and as I mentioned before I have run across this only a couple times in all my years of repair and I recall this particular issue being related to a motor change or a motor switch change.

let me add or possibly a "Mis-Wire" where a wire got placed on the wrong terminal which can happen if the switch has been changed at all from the original or the wire coloring is not exactly the same
