I have a Kitchenaid refrigerator model kbra22klss01.

SOURCE: refrigerator stopped working, freezer works fine

Sounds like the evap fan is not running. The fan takes cold air from the freezer to cool the refer compartment. If the freezer is cold the compressor is running. Generally the freezer will stay cold since the cooling coils are there but it must have the fan working to get the air up to the refer area. Pull everything out the freezer and take the back panel off to view the coils and fan, etc. It's a simple easy job to change the fan. If you find the coils are a total block of ice then it's another problem... the defrost cycle isn't working. Sooo... see if the fan is running in the freezer compartment first. See http://www.partselect.com/Schematics/Maytag/AA43-57.gif for fan location, item 18 is the fan motor. Let us know what you find out.

SOURCE: freezer not working , clicking noise coming from fridge

Clicking was a relay. Replaced relatively inexpensive relay and now working fine.

check the damper which provides air flow to the fresh food side

Problem seems to be solved. I unplugged it for a short time and plugged it back in. I'm guessing it needed to be re-set.

Based on your complaint, it soumds like you have a malfunction in the defrost system.

Listed below are some tips provided by, www.repairclinic.com, which can assist you in diagnosing your problem.

This link will describe how a refrigerator works.

Here is some diagnostic help!

Cooling is poor For an overall understanding of how refrigerators should work, read about refrigerators in the How Things Work section of our website. A refrigerator or freezer that is cooling, but cooling poorly, may have a problem in one of several areas:

Evaporator coils
Condenser
Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt.

Evaporator coils 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

Condenser Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush (see the Appliance Accessories section) and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.
