Whirlpool Duet Gas Dryer Motor Won't Run - please help

61 posts in this topic

<<<Thermal Fuse not used in Motor circuit on Gas Dryer..>>>

 

**********

 

Yes---I keep forgetting to remember that the electric dryer Thermal Limiter (on the blower housing) is in the motor circuit---but NOT the Gas model:)

Question: Is this correct?

 

The Thermal Limiter on the blower housing (circuitry) is the same on both DOYT (Dryer of Yesterday Today) and DOTT (Dryer of Tomorrow Today) dryers:)

 

GAS MODELS: Failed Thermal Limiter---motor runs but no heat

 

ELECTRIC MODELS: Failed Thermal Limiter---motor does NOT run

 

Thanks:)

Hey KurtiusInterupptus, appreciate the follow up :-)   Haven't had opportunity on Friday, but was able to do some trials today.  Some additional info, but no root-cause for sure.

 

  • P9-1 to P9-2 jump = motor runs.  New replacement motor ran first, then I switched to my original one and it also runs, so it's not the motor for sure.
  • I checked various points again with multimeter with door opened, closed, to belt-switch, etc.  It pretty much reads everything the same as before.
  • Observation: my original CCU has motor relay that is traditional, where I can hear the click after start button is pressed.  2 newer CCU have blue housing, PN: SLA-S-112DMJ-F-30, which I believe is solid state relay, so it makes sense why it's not making same click noise.  Reason why I'm bringing this up is because I believe the issue is in the motor relay; my old one may not be working correctly even though it is making the sound, and newer ones may not be working for different reason(incompatibility?).  It's hard to be sure without looking at CCU diagram, but everything else appears to be functioning correctly.  Perhaps newer CCU don't work with my user input control boards?  Not sure.  When I check P9-1 with start button pressed, it stays at 0v, which doesn't make sense.  I would expect some kind of load.
  • Observation2: the original CCU board and newer CCU boards have same silkscreen PN: W10179483 Rev A.  So I think the board is the same, only 2 difference that I could see are a) motor relay, B) 1 unused connection housing removed on newer for cost saving I suppose.  Date codes are different obviously; 2 newer boards having almost same date code.
  • Observation3: it's curious why at P9-1 or at belt-switch is giving 104v consistently, and why not 120v... and I do not know if 104v is by design and if it is enough to start the motor.  I am wondering if 104v is just a noise within CCU and line also, and not necessarily the actual load reading IF motor-relay was working correctly.

I'm pretty much down to CCU again, and maybe outside shot at user input control panel not working with newer CCU.  Everything else appears to be working OK; motor, harness, thermal fuse, thermistor, moisture sensor, door switch, and belt switch.  The question is, do I purchase a 4th board from repairclinic this time? (previous 2 were from partselect).  But I have strong belief that I will get almost the same board as the last two... I think it is the correct board, it's just not compatible perhaps with something.  I even thought about posting local craigslist ad to see if anyone has same WP Duet model nearby, then barrow CCU for an hour with $$ exchange... very long shot I'm sure :rolleyes:

**********

That is a definite possibility.

I've had this *once* several years ago on a Whirlpool Dryer---replaced failed Central Control Unit (CCU) and the dryer did NOT respond to input (no start---but some LED activity on Control Panel).

There was a Service Bulletin about this (different model dryer)---which explained that the *revised* CCU basically "speaks Russian" and the original User Interface (UI)"speaks Chinese" (not compatible).

LG also had one like that---about 5 years ago...

If you call repair clinic with the pn off the original board, they may be able to tell if there was midsream change that was made.

ISSUE CLOSED, Dryer Finally Running.  FIX = replacement CCU.

 

Thank you all for your assistance with my dryer issue, this forum is an excellent source of knowledge, and those who assisted me I can't thank you enough.

 

As for the fix, I ordered the part from RepairClinic-- great service and I love knowing that buying from them through the affiliate links on this site helps support the wonderful work you guys do here.  And you just can't beat the one year return policy!  

 

LESSONS LEARNED:

1) Learned great deal about a dryer :-) 

2) Don't rule out possibility that new replacement part is working or compatible based on claim.

3) Buy it from Repair Clinic (it's the truth without sounding like a sales pitch), especially if you're do-it-yourself novice.  My motor return was smooth and extremely fast (refund processed same day from reciept).

4) Doesn't hurt to keep quarters around the house for these laundry emergencies.

 

BTW, I learned that ~104.4v I was getting from certain points were by design, not representative of actual load (which makes sense)  :-)

 

Cheers!  :-)
