The freezer section is very cold and the refrigerator is warm and the other day it was freezing the milk now its warm again please help.
You will want to remove the rear cover in the freezer compartment and check to see if the coils are impacted with ice. If they are then you would want to do a continuity test on the defrost heater and thermostat. If either does not have continuity then you will need to replace that part. If they both check ok then you would want to test the defrost thermistor to make sure that it is within range. At 0 degrees the thermistor should have 42.5K ohms of resistance. If outside of range then replace the thermistor. If the coils do not have frost impacted on them then you will want to check the damper assembly for proper opening and closing and test the thermistor in the refrigerator compartment. It should read approximately 14K ohms at 37 degrees and if outside this range then replace the thermistor. If the damper is not opening and closing properly then replace the damper. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
Fridge section cools fine. Freezer not freezing very well even though turned up to max of 9. Top shelf at about 20 degrees, bottom basket at 11-15 degrees, but did reach 6 degrees after being away from home for a month. Refer used to "moan". That has stopped. Fan down at bottom in back goes off when either door opened; otherwise it runs all the time. Water seems to be frozen in ice cube tray, but cubes not being dispensed (ice maker is turned on). A little bit of frost accumulation on back interior freezer panel.
You will want to pull the rear cover of the freezer compartment to check the frost pattern of the evaporator coils. The evaporator coils should have a full even pattern of frost on them. If not then you will want to check the condenser coils to ensure that they are clean and check to make sure that the condenser fan motor is operating. If the fan is not running you will want to check to make sure that it is getting power. If it is then replace the fan. IF coils are dirty they will need to be cleaned.
