I am trouble shooting a fairly new (about 3 years old) GE side by side refrigerator defrost problem.  I've already determined that the heating element is bad (with an ohm meter) and I just replaced it.  I was hoping to "test" the whole circuit by forcing a defrost cycle, but, after searching everywhere for the defrost timer, discovered that it has been replaced with a "high tech" electronic PC board.  I've been reading here that there are various ways to force the defrost cycle and I've tried all the ones I could find but with no success.  So I was hoping you might know.

Model : GSH22KGMCWW  (GE side by side refrigerator) SN: VA237758

I apologize if this question has already been answered in a previous posting.

Also, just for my future reference, does GE map to any other brands (e.g. Frigidair)?

Thank you for your help!

There is not any way to put this ref. into a defrost cycle on this board.  Will just have to wait and let it do it's thing.   No G.E. is G.E, sadly.  But the Firgidaire is just as bad with this new electronic stuff but is not the same MFG.

   I've been putting them into defrost and running diagnostics for years now.  Of course I have the membrane and board and cable and book.  If your console has at least 5 buttons, you should be able to enter diagnostic mode and initiate a defrost cycle.  If you found an replaced a bad defrost heater I would say you've fixed it already. 

   When I'm on a call and I have a frosted evap coil I jump "Line" to "Def" with an amp probe around "Def".  I use that piece of solid wire bent into a U we all have in our pocket. I put it between line and def on the main board and turn it like a key.  If it makes a pretty little blue spark and my amp probe go up I know my heater and terminator are good.  At that point I'd suspect moisture in the evaporator thermistor.

Yes the board can be tested for defrost, and if you have the equipment you can run the diagnostics.  The question for the home owner was how to put this board into a defrost cycle and this will not be done.  Jumping the board will just test the circuit, will not put it into a defrost cycle, the ref. will still be in the mode it was in before the termilals were jumped.  This is why I gave him the answer I did.

Thank you both for your information.  I installed the heater coil on Monday evening, so tonight I'll remove the back freezer panel and see if everything is working.

Just a commentary on technology...I find it disappointing that some appliance manufacturers "purposefully" design their products to require special tools/cables/diagnostics boards in order to be serviced.  This especially annoying since it is clear that it doesn't have to be that way, case in point, blink the refrig light switch 5 times and a defrost cycle is initiated.  I also can't believe that enough people fix, or attempt to fix, their applianes themselves to put a dent into the appliannce repair industry.  I know that I will be checking this site when the time comes to purchase a new appliance to see how serviceable it is.  In addition to my normal purchase criteria (features, reliability, price, etc) I will now add serviceability.  Man, that would be a great enhancement a web site to rank manufacturers by the serviceability of their products.

Thank you again for your help.

You are welcome, and we all agree this new stuff out there is stupid.  Just stay with the tried and true old design.  We run into this new crap every day and have to figure out which can opener will work on it this new one !!!  ;)
