This posting is for a service manual for the GE Profile Refrigerator PDS22SISBLSS
. Local GE service people (Flick Brothers Electric - Bloomsburg, PA) are just parts replacers. The say they don't have manuals, don't know how to put the frige into diagnostics, or how to interpret the codes. So far they have replaced the mother board three times and the freezer and refrigerator thermistors. The first board due to condenser fan not running. The initial problem still exists with varying frequency. Both frige and freezer start to rise in temperature. Two more mother boards and two thermistors and still an expensive box that does not keep cold.
I previously replaced the motor run capacitor due to very high motor current (7 amps - locked rotor). After replacing capacitor motor current is less than 1 amp.
Since on vacation today, I removed freezer hardware and evaporator cover. The evaporator is just about a solid block of ice. This is why no cooling with the fan running on high speed. But, still does not explain why. Checked evap heater and thermodisk, in series, with 31 ohms resistance. Found a place on the web that says it should be 37 ohms. Seems close enough.
Found another thermistor buried in the ice, attached to evaporator tubing. Green tech data schematic, from underneath the frige, shows three thermistors. With frige off and defrosted, measured resistance back to mother board J1. FF1 thermistor= 5.5 kohms, FZ thermistor = 5.7kohms, Evap thermistor reads 17.9 kohms. Ambient temperature in kitchen about 74 degrees F. Found table on internet for thermistors. 5k ohms is OK. 17.9 kohms is about 28 degrees F. Hmmmm something is different here. Maybe bad thermistor!!!!
The Evaporator thermistor was not replaced by Flick Brothers! I don't think they know it is there!
I have an associates degree in electronics and can understand this technology, if the proper manuals are in hand. Can anyone help?
Now that I have told my story maybe the website will let me download another manual.
