      [Webinar] Appliantology Workshop   11/09/2017

      Information is the name of the game in the appliance repair trade today. Appliantology is a powerful information tool for the professional appliance repair technician. But just like with any of the more capable tools in your tool bag, many of the more powerful features are hidden from you unless you "read the manual." Ugh! Who wants to do that? Well, this is one time when you don't have to! In this webinar, Team Samurai will personally walk you through the site and show you many of the useful and powerful features that even long-time users probably never knew existed.

Helps, not sure if controls are electronic, has manual dials.   Got last minute call at 8 this evening, Owner is from Oregon, has renters in house.  Stopped by for a look, was 2 minutes away.    Back wall is froze solid,  food is spoiled.  Fans are running.  Turned unit off & evaporator fan continues to run until I push door switch in then it shuts off.  Back on when I release.  

 

Will defrost with steamer in morning & check heater.  Did not see in manual how to initiate defrost cycle.   Any more insight to diagnose defrost cycle,   GE's are a little difficult for me cause have not had the experience with them.  

 

  Forgot to check thermistors to see if old style.   Have not received my order from Durham for his fancy dancy therm ice test container.    Bet they would work on the defrost limit also.

on encoder models, test the defrost circuit from the board. Unplug fridge, disconnect blue connector from board. Do a continuity check between the blue wire on the blue connector and the orange wire on j7 pin 9. This does a continuity check through the limit and the heater. you should get around 22 ohms. If you don't find continuity, do a continuity check on the heater and limit inside the freezer. Remember, most GE's have limits that open at 140°f so it should be closed. Those limits rarely fail. If limit and heater pass, then test your thermistor. If it is good, then replace the board (and evap thermistor)

Ok.. Don't be afraid of GE's. They are actually quite fun. Listen carefully, just in case you are caught without the specific manual for your model,. always have the following "GE Fridge Survivors kit" available at all times:

Unit wasn't completely defrosted after leaving unplugged & open overnight.   Finished with steamer.  Checked defrost heater direct.  It was open & black.  My parts supply was across street so I picked one up & a thermistor for the evaporator.   Changed both out & restarted unit.   Started frosting the evaporator almost immediately.   Took a chance that the repair was complete I was running behind On a scheduled call.  If I have to return it is across the street from supply store which I visit often, no big deal.

 

Tonight I will study the manuals I downloaded.   Love my job.
