Question about Refrigerators

1 Answer

I have inherited a Jenn-air model # jcb2389grs and I notice the refrigerator is not cooling properly. I do not notice any air circulating to the top shelf when the freezer door is closed, but when the door is opened then I can feel the cool air com through the vent. The freezer is working fine, but I have noticed frost build up along the hinge side of the door. Can you tell me what the problem could possibly be?

First refrigerator stopped cooling, next freezer. Seemed like it was trying to defrost but their was lots of ice built up on coils. Jen-Air side by side, counter depth model number JCB2388ARB.

Causes of ice build up on coils:
Not enough freon (leak). Coil defrost heater not working (Coils on all freezers freeze up, but you should not notice). Coil defrost timer not working. Compressor thermostat not working (or end fell out of proper location).

Frozen @ bottom, warmer(but cool) @ top
what your looking at is the pictorial break down of the freezer compt.
If the fan is important for airflow i would inspect part 3 as well, this is your defrost t-stat and controls when you need to go into and out of defrost, with extra frost i would tend to think your not goin inot defrost and its building up, not allow the fan to circulate the air properly.
while your in there you might want to check the heater as well
take a multi meter, and check the heater for continuity, sometimes these bend all out of shape as well and dont connect they way they should

I have a Jenn Air side by side model # jcb2389grs and I have noticed the last couple of weeks that it is leaking underneath, mainly by the freezer side, it seems. I inherited the fridge and don't have an...

sounds as if when it goes into defrost there is a tube that runs down the back of the unit inside the exterior casing. This tube empties out onto a small tray the sits right on top of the compressor in the back bottom of the fridge What this does is use the heat from the compressor to evaporate the water from the defrosting cycle. Check the back of the unit to see if the tube is sitting in the pan if not place it there and your problem is solved. Good luck on your repairs

Frig not stayng cool. Freezer not freezing

most fridges have a evaporator dish or container.
it must be emptied ...and cleaned and disinfected.

now-a -days they are usually mated with the compressor and cool this unit down. notice there is no coil along the back of the is usiually behind the fridge at the bottom with a cardboard or plastic access cover...
this will make the unit cool better and return the cooling to normal....
clean out your freezer...i bet it's full of 4 month old packs of something you'll never eat....this will let the freezer breathe and circulate air to the coil ...i bet it has 3 in of ice on it...yikes...your not alone...most people do this...\
get a freezer if your getting ready for the apocalypse and liberate some room.
good luck

The damper control is not working but I cant get to remove the cover in order to replace it

against the back panel there are 2 finger holes on that cover, at the same time stick your fingers in the holes and pull down to avoid the locks and then slide the cover out.
