Title: GE Hydro Wave Washer -Mode Shifter Ghetto Repair
Post by: goodsusedappliance on February 25, 2013, 04:08:42 PM
I opened up the solenoid on the mode shifter WH38X10017 (http://click.linksynergy.com/fs-bin/click?id=omv7WULuxaw&subid=0&offerid=225193.1&type=10&tmpid=2111&RD_PARM0=http%253A%252F%252Fwww.appliancepartspros.com%252Fge-shaft-mode-shifter-wh38x10017-ap4380186.html&RD_PARM1=http&RD_PARM2=%253A%252F%252Fwww.appliancepartspros&RD_PARM3=.com%252Fge-shaft-mode-shifter-wh38x10017-ap4380186.html).  There is a thermal cut-off wired on to it.  I bi-passed it and put it back together and everything works fine.  Is this a bad idea?

Cool. Ain't no bad idea long as you put a bullet fuse in there or the equivalent. I would love to see that too. How did you get into it?
The older washers would work fine UNLESS a person added a garment after that solenoid was initiated. Instead of being activated for seconds it stayed on for minutes thus it would blow the solenoid. This is the first I have heard of a limit within the circuitry.

  The coil cover is riveted on so you just have to drill them out, remove the internal fuse and solder the wires directly. Use heat shrink to insulate. You should install an external fuse holder with 2 amp fuse. Use screws and nuts to reinstall the coil cover. There was a web page with pic's that someone did but I can't find it now.

Sorry I didn't take pictures.  I pulled out the tub & flipped it. I removed the drive pulley.  I drilled out the rivets holding the solenoid on.  I snipped the red & yellow wires to pull it through. (leave plenty to re-connect)  I removed the plastic housing holding the windings from the metal housing.  I removed some of the tape holding the wires down.  I found
http://www.aupo.com/products_detail/&productId=1dc42fb5-c9a6-4da5-ae4c-941072324fa5&comp_stats=comp-FrontProducts_list01-004.html
this thermal fuse wired between the winding & the Yellow wire. I cut the fuse out and soldered the wire straight to the yellow wire. I used high temp fiberglass tape to keep the wires in place. 

The fuse was rated at 130C witch is 266F.  I'm not sure where to find a fuse so small. I was thinking of trying to burn it up by leaving the door open... just to see what happens.

Technicians do not have bad ideas. Just some ideas, that need a little modifying. After all, we make the things engineers design work. How long did the repair take you, and could you do it in there home without taking the shifter back to the shop?

I just changed a mode shifter out so I opened it up.  It has an A8-5A-F (http://www.aupo.com.hk/products_detail/%26productId%3D545516bb-962d-4a32-ad2a-836db440759e%26comp_stats%3Dcomp-FrontProducts_list01-004.html).  It's rated a little hotter than yours, 150C. I couldn't find it for sale so I crossed to an NTE8035 (http://www.nteinc.com/specs/8000to8999/pdf/TCO2.pdf). It's $1.25 plus shipping at Mouser (http://www.mouser.com/ProductDetail/NTE/NTE8035/?qs=%2fha2pyFaduh7mzbK5fCEfHEZuzjCPZNrbqkb9lwdg3k%3d). The 130C fuse crosses to NTE8020, same price. The windings look good, no burning, 65 ohms.


I haven't decided if I'm going to repair it or not.  It's only the second mode shifter I've replaced.  I think they're pretty reliable as long as you don't leave the lid up on the older ones. I wouldn't repair one without a new fuse, bypassing safety devices is never a good idea.

may i ask what leaving the lid up causes to the mode shifter? thank you

  The inverter applies 135vdc to the mode shifter coil to energize the solenoid for around 15 seconds or so and then reduces that to 30vdc as that is all that is needed to hold the armature in. If you open the lid at the wrong time in the agitate cycle, 135vdc will again be applied for too long a period of time causing the thermal overload to blow. The firmware in newer versions of the inverter has been modified to prevent this from happening.

I have a mode shifter job this weekend.   I have one customer,  he has about 20 GE Commercial washers,   I have already done 3 for him.    Im gonna take the old mode shifter and try this.    I think the external fuse would be a good idea,  maybe an auto fuse and holder.  You can get them at radioshack for about 5 bucks for both.   I'll sell him a " rebuilt " mode shifter for less,  we both win.   I hope this works.

I would replace the inner fuse. It's a thermal fuse, an external fuse would not trip if the coil overheats.

Good Idea JW>    Got company this weekend,  letting the job go to sometime this week.   I was now even thinking some kind of little "circuit breaker"  if it goes out,  all I would have to do is stop back and reset it.   

Title: Re: GE Hydro Wave Washer -Mode Shifter Ghetto Repair

  As tgoods has suggested, this is a thermal fuse and operates on the overheating of the coil, not the amperage draw. The thermal fuse is rated at 2 amps. The shifter requires 135vdc to the coil to engage the solenoid and then switches to 35vdc to hold the solenoid in. At 135vdc, the coil is drawing less than 1.5 amps. The problem occurs when the lid is opened at certain times and the 135vdc is applied for too long a period of time. The coil overheats and opens the fuse. An external standard fuse that I suggested before or circuit breaker is not going to provide protection.

goodsusedappliance: what was the coil resistance on yours? There are two different versions. One uses copper wire and has a coil resistance of around 98 ohms and the other uses aluminum wire with resistance of around 65 ohms. That may be why there are two different fuses used.

I'll have to wait to get another used one.   Guy decided to wait and plunk in an old maytag he had that just needed belts.    I'll get one eventually.  I can't wait to rip one apart now.

Has anyone replaced the RS6006 bearing which is available from most industrial bearing suppliers. My shaft mode assembly is performing properly in the engage and disengagement process, but the tub seal failed resulting the tub sleeve bearing wearing and gauling, and the RS6006 bearing inside the mode shifter is also not spinning smoothly. I disassembled the assembly and I am ready to press out the bearing, but before I do, just wanted to see if anyone has successfully done this.

just wanted to ask,is it really necessary to remove tube to get mode shifter out?ive laid this machine on its side and removed bottom panel,access seems to be all there!by the way i have a good motor for this machine if somebody needs one

  Well, you have to at least remove the inner tub as it is attached to the mode shifter. It's a lot easier to service with the whole outer tub out and inverted.

 :)   This actually works !      I didn't know what to expect when I opened up the coil.
You have to be careful not to break any wires.  Before I started I took my ohm meter
and  there was an open.  Looks like the fuse blew.  I peeled back the wires and
it was obvious where the fuse is.  There is only one part besides the wires.
I just twisted the wires together AT THE END OF THE FUSE  and left the fuse in.  Black taped everything back up
and got my ohm meter out again.  93 ohms or so  ;).  Cool ..... 

To do it right you should put in an inline fuse ON THE WIRES RUNNING back to the motor which I will do.
Put everything back together and 4 blinks. Bummer.  But I DID THE LEAVE POWER OFF TRICK
AND LIFT THE LID 6 TIMES IN 12 SECONDS AND WOW.  1 BLINK EVERY SECOND.    WASHER FIXED. IT WORKS.  THANKS !!!!
WIFE HAPPY AGAIN.

  Providing an external fuse is not going to provide the protection that the internal fuse does. The internal fuse is a thermal device and will open if the coil gets too hot. The coil requires 135vdc to operate the solenoid but then drops to 35vdc to hold the solenoid. If the washer lid is opened/closed during a certain time in the cycle, the inverter board applies the 135vdc for too long a period of time and the coil overheats. This has been fixed by a software change to the inverter board. To really fix the problem, you need to replace the motor/inverter or refrain from opening/closing the lid after you have loaded and started the wash cycle.

Thank you for the comments.  My wife says she did open the lid frequently to check on the water level ( don't know why).

She says she will stop doing this.   It seems you know this problem in great detail !    If you stopped the wash cycle and then
opened the lid, close the lid and then pulled the knob to start the cycle again do you think this would be better ? 

Sounds like she should just let the machine do it's job.

THank you very much for your comments and knowledge !

Regards,

John

How about a self resetting TCO? Then you won't have to worry about changing the motor to update the firmware...

Hello,

Seems I have the same symptoms as described here with mode shifter open and engaged (clunking during agitation).

My question- any issue with limping through with washer in this condition (i.e., not repairing)?  Don't want to invest time/money into this machine.  Can it be used reliably or eventually tear itself apart and motor fail next unexpectedly?

Thanks for such a great resource and information.

  Not a good idea. Hard on the motor and mode shifter. It's not designed to agitate the whole basket full of water.

I've attached a bit of a service memo telling you which motors cause the failure.

This information is amazing! I have one of these washers with the same fault, except it also has a broken belt and the base of the timer won't turn with the handle part of the knob (you can hold the base and turn it that way, so I assume something is stripped). I think the broken belt may be related to the shift coil failure, causing overload on the belt.

So, how about replacing the thermal fuse with a self resetting thermal overload? I have less experience than many of you, but I've seen self resetting thermal overload protectors in a clothes iron and a bottle warmer. Has anyone replaced the thermal fuse with a self resetting thermal breaker? Is there room inside this thing for that? I haven't yet taken mine apart.
