GE French Door Refrigerator Service Mode, Test Codes and Fault Codes (PFE28, PYE22 and Related)

We typed this up from the two technical data sheets (pub. 31-51919 for the case and 31-51916 for the door, dated 05-15) that came with a GE Profile refrigerator, model PYE22PSHISS. The sheet covers a whole family. Variable speed models: CFE28, CWE23, CYE22, GYE22, PFE28, PFH28, PWE23, PYE22 and ZWE23. Single speed models: DFE28, DFE29, GFE26, GFE27, GFE28, GFE29, GNE26 and GNE29. Some tests only apply to models that have the feature, such as hot water, a deli pan or a feature board. Check the sheet that came with yours.

This is service technician information. The sheet warns of electrical shock hazard and says service should be done by a qualified technician only, with power disconnected before servicing. If you're not trained for that, call a technician.

Entering service diagnostics

Press the Water, Crushed and Cubed buttons at the same time for 3 seconds.
The display shows 00 in the freezer temperature display and 00 in the fresh food display. All the components turn off, the 3-way valve goes home, the dampers go to the closed position, and the temperature display shows 00 in each display.
On LCD displays, use the up and down buttons on the left to change the number.
Change the ones place to select the test you want. Press any key other than the temperature adjust keys to run it.
You have to select a test within 5 minutes of entering diagnostics or it times out and the refrigerator goes back to normal.
Once a test is selected, the display shows the result of the mode.

To exit, run test 0016. The control also resets to normal operation if power is cycled. A non-dispenser model needs a service kit.

The test numbers below are four digits. The first two digits are the freezer display and the last two are the fresh food display. For example, test 14 is entered as 0014, and the exit test is 0016.
