GE PFS22MBSBWW evap fan removal

5 posts in this topic

hi, new to site haven't posted before.  Looking for two things really a wiring diagram for a GE refrigerator PFS22MBSBWW and a bit of a description of how to access the evaporator fan motor.  I know the Motherboard is bad as I have already jumped out the wires going to the condenser fan motor, so I would like the diagram to see if I can jump power to the evap fan motor (its not running right now).  I am going to be replacing the mboard this week, but need to get the frige cold sooner than I can replace the board.  Thanks for any help.

 I know the Motherboard is bad as I have already jumped out the wires going to the condenser fan motor,

 

What wires did you jump out and how did you know what to jump without a wiring diagram?

 

 

Here's your minimanual:  http://appliantology.org/files/file/717-ge-bottom-mount-refrigerator-pds20mfwc-pfs22mbwb-pfs22miwb-pds22sbsd-pds22mbwc-pds22mbwb-31-51726-minimanual/

 

Part link to your muthaboard.

 

Main-Control-Board-WR55X10942-01091474.j

 

Check to see if the muthaboard is putting out 12vdc between the red and white wires on the J2 connector.  If it's not, you can power it with a 9 volta battery or an external 120vdc power supply until your new muthaboard comes in.  I would say that could borrow the 12vdc from somewhere else on the board but it looks like the only steady 12vdc supply is for the evap and cond fans.  

 

To power the fans with an external supply:

 

Connect white to negative

and both red and yellow to positive

 

Do not reverse the leads or you'll be replacing the motors, too.  

 

Speaking of which, do you see any burned resistors on the muthaboard?

On Ge profiles and Arcticas, always test/replace thermistors and test fan motors before you replace a board. Your board could be responding to information given to it by a bad thermistor and a bad fan motor can burn out a new board.

I found a copy of the wiring diagram spring of 2012 on line and couldn't find where i stashed the diagram....i 'm an hvac tech. I tried for a few hours last evening to find the diagram to no avail. I did have an opportunity to pick up the board today and replaced it tonight. All is well, frige is cold and all components are running correctly. The digital temp display even works now! Thanks for the help, much appreciated. I really have lost faith in GE after several appliance purchases over the years all of which had premature deaths.
