Question about Jenn-Air JCB2059G Bottom Freezer Refrigerator

1 Answer

Freezer building up lots of frost, but on lowest setting.

Could thermostat dial be reversed? On the very lowest setting, the freezer is holding fast at 8 degrees, with plenty of frost building up & never defrosting. This is a new fridge. Thanks!

    thanks for responding with your helpful tips! i thought that 8 degrees was too cold, as the freezer has so much frost & now icicles building. didn't know anything about a fan -- very helpful. as the fridge is brand new (and we're renters), i haven't contacted the manufacturer (and nothing in the user manual about this as even a possible problem). ha!

I have a side by side and the freezer is working fine and refrigerator is not cold


Hello.
If you open the freezer door and look on the back wall do you see frost build up on the back wall?,if so yes thier is frost build up in the freezer heres what to check.

DEFROST HEATER ...remove back wall of freezer and you will see a black heater at the bottom of the coil thats frosted up,it looks similar to the bake element in your oven,or in some cases it is going to be a spiraled wires inside of a glass tube. To check it,use a multimeter set to the lowest ohms of resistiance setting and follow and find the wires at the top of that frosted coil,unplug/disconnect those wires and check for continuty with around 5-20 ohms of resistiance. If it has that amount of ohms the heater is good. If your meter display does not change or displays OL the defrost heater is broke and needs to be replaced

DEFROST TERMINATION THERMOSTAT... it's round and has 2 wires and clips to the top of that frosted up coil. IT MUST BE CHECKED WHEN COLD SO BEST TO DO WHEN FROST IS STILL BUILT UP. To check it disconnect the wires on it and check for ZERO ohms of resistiance. As with the heater if the meter display OL or doesnt change,it is the problem

DEFROST CONTROL...it is hard to check for a semi unskilled person and if the heater or defrost t-stat check good its going to be the problem. It will NOT be in the freezer it could be on back wall or inside the control panel in the refrigerator section.

Good luck,
Gene

Side by side thermostat set low seems like it runs a lot more than it use to freezer and fridge are boyh cold


Check your coils underneath the fridge to be sure they are clean.
Check your condensor fan (bottom rear of fridge) to make sure it is blowing air freely.
Make sure you have a good supply in the freezer, All of your cooling comes from the freezer section and a mostly empty freezer will result in more frequent running as ther is not enough stock to help maintian and hold freezing temperatures.
Check your freezer section to make sure there is no visible frost on the back wall of the freezer (down low on the panels behind and slightly above the lowest freezer basket. If you see frost starting to develop it means you have a defrost issue starting and will want to adress it rather quickly. Either a problem with the defrost control board (inside fridge/freezer control compartment) or the defrost thermostat (behind the freezer back panel on top of the evaporator coils).
Hopefully this helps!

Poor cooling in the freezer compartment


Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets. The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited. Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system: The defrost timer The defrost thermostat (also called the bi-metal switch) The defrost heater If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem

Freezer thermostat stuck on A frost build up in


check the coils underneath and behind the freezer. the back on may be inside on the back wall behind a false panel. If so, disreguard this one. Take a vacuum cleaner and **** as much dust out as you can. This sounds like air flow restriction causing icing on the coils making the freezer go into defrost mode(for the evaporator coil). Also check to see if you hear the fan running when yoiu open the freezer door. It can be replaced if bad

Freezer compressor running constantly


Below the evaporator fan behind the back cover inside the freezer is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

How to check everything
http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php
If it's heavy buildup-
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

Freezer temp very unstable... lots of ice build up on inside inte


This appears to be a defrost problem. Either the defrost heater is burned out or the defrost thermostat is defective. Look into the rear wall of freezer for a layer of frost building up that will tell you that there more than likely is a large area of snow and frost building up on the evaporator coil. Once you manually defrost the coils you will be able to see the part number WR51X10038 Defrost Heater. It has a glass tube on the outside so it will be easy to spot if the defrost heater element inside is burned out. If you change the defrost heater I recommend that you replace the defrost thermostat part number WR50X10054 Defrost Thermostat. The defrost controls on your model come from the mother board so the is no defrost timer or adaptive defrost. The mother board make the decision when to defrost. When you are able to unplug and inspect the evaporator coils in back of freezer back wall panel let me know what you find, Thanks Sea Breeze

Freezer building up with frost


Sounds like the defrosting system has a faulty timer/board, faulty heating element or bad electrical connections to these components.

6343ed3.jpg The problem is ice build up on the back wall. The noise you hear is the fan blades hitting the ice. On the back wall water gets trapped, it then builds up over time, and a big ball of ice forms and blocks the fan. Take off the back wall, defrost the build up and cut the insulation off as above. The water will no longer get trapped and the problem will not come back.
