The frige is not getting cold, however, I noticed when I open the freezer, the air from the vent gets colder and stronger, but when I close the freezer door, the air does not come up as cold and strong.

I tried using the instructions given, but I can't locate the defrost timer described in the directions.

You have an adaptive defrost pc board in this. If you go to web site www.applianceaid.com, you will find two proceedures there to force defrost.
You also can remove the back freezer panel and check frost pattern, if heavy, total frost, defrost with a hair dryer.

Defrost board is Item 6 in Section 3.

You would expect better air flow with the door open as there is less resistance to air flow with both doors open.

Check that the vent lower down on the dividing wall is clear on both sides.
It must be for proper air flow in the unit.
A common symptom of a blocked vent is a fresh food side that is cold on the bottom and warm up top.

See the attachment for the tech sheet, it has how to force a defrost.

If the evaporator coils in the freezer are heavily iced/frosted up I would do the following.


First remove the evaporator cover in the freezer so you can see the coils.
Do not let them de-ice.

If yes.
Manually force a defrost cycle, see the tech sheet. When the fans and compressor turn off, you are in defrost.

Now check the defrost heater to see if it is on.
Be careful you do not want to burn your fingers.
If the heater is on then the defrost board (Item 6 in Section 3) needs replacing

If not on.
Unplug the unit.
Remove the wire for one side of the heating element (Item 33 in Section 12) from the wiring and measure it for continuity, usually around 20 to 30 ohms.

If the heater is OK
Remove one wire to the defrost thermostat (Item 6 in Section 1) (it will be clipped onto the defrost coils) and measure it, should be 0 ohms when frozen. Note that it opens just above freezing so must be frozen to check it. Also inspect it, if it is bulged at all replace it even if it measures OK.

If both the above are OK then odds are the defrost board is toast.
Best way to test this is a live test to see if you have 120 volts across the heater/defrost thermostat combo.
