Both compartments are not cooling. Power is running to refrig, ligths go on and off. Digital temperature buttons displaying dashes instead of numbers like usual, and cannot be adjusted. Fan is not blowing, even when push light button (door closed). Please help!

Re: Both compartments not cooling
It sounds like the control board may be gone. If there are no fans running or the compressor running then it will never cool of course. I don't think it's stuck in defrost mode since you say the display shows dashes vice numbers. Go to this site for diagrams, etc. Item 11 is the controls section.

it could be 1 of 3 things,1st: the ptc overload on the compressor has welded together and cant cycle on and off/2nd:the cold control is defective,this component is the part you set the units temperature with/3rd:your damper vent door located between the freezer and refrigerator compartments could have frozen open from condensation and cant close to keep the cold out of the refrigerator after the refrige is cool enough,this is behind a plastic grille in the refrigerator and brings in cool air from the freezer
Check and make sure the fan in the freezer is running. if not possible bad fan. If fan is running, check to see if you have any ice built up on back freezer wall. Normally frost type ice. If so, you may possibly have a bad defrost bi-metal mounted in the freezer section. Next could be a defrost timer control. Model number usally will help more in getting it right.
Check your condenser coil (should be below the refrig.). If dirty, you can clean it with a condenser brush from Home Depot or Lowe's. Turn the appliance off while cleaning. Be careful not to damage the refrigerant tubing (copper). If this doesn't solve the problem, then there may be an issue with the defrost thermostat, defrost heater(s) or the main temperature control assembly.
check that the fan in the freezer is running,it circulates the cold air,if it isclose freezer door,open refrig. door lookto the upper left you will see where the cold air enters the refrig compartment and should fill air coming thruough vent this is a motorized unit and they sometimes fail,also check the return air hole located at bottomof refrig.sometimes get blocked by plastic bags etc
There is a damper door that opens and closes when you move the thermostat. I would bet the door is functioning incorrectly. All the cooling of a refrig comes from the freezer and gets blown into the refrigerator compartment. If that damper door is open too far it will have constant freezer air blowing in....and if it's not open enough obviously the refrig will not get cool. Look at the upper left corner of your refrigerator, the center rear wall of the refrig or just feel around for a vent will cool air blowing out of it......Then take it apart and see if anything is broken.
The freezer get the first crack at cooling and combination units have a fan and adjustable vents to steal some of the cooling capacity for the refrigerator.
The vent are normally located in the back of the refrigerator compartment and with these, you can balance the cooling capacity between freezer and fridge.
I recommend you swap your thermometer back and forth until you get the balance you want; typically the freezer should be at 5 degrees F or below and the fridge at 35-40 degrees F.
Adjusting the control for temperature and having the vents set to supply the cold air you want in each compartment should give you the range you want in each.
Either the fan that blows cold air from the freezer compartment to the fresh food compartment is burned out or the door/flap that seperates the compartments is stuck or the linkage connecting it to the fresh food temperature dial is stuck or broken.
The evaporator coils are in the freezer compartment and air is blown from the freezer compartment to cool the fresh food compartment. For some reason, air is not moving to fresh food compartment.
If the fan is running, it could be something as simple as Ice blocking to door between the freezer and fresh food compartment. I know modern refrigerators are self-defrosting, but that's only the evaporator coils, which are defrosted by a timer and a heater.
Ice can form on passageways inside the refrigerator, like the exit of the ice maker and in this case, on the door and 'tunnel' between the freezer and fresh food compartment. It's free, and doesn't take a lot of time, so try completely defrosting the unit before doing anything else.
BE SURE to keep the doors open, as odors can form as particles of food are allowed to defrost that may have been frozen in an ice pack for months or even years. Clean the interior of the refrigerator while you have everything out and reset the controls to normal settings.
If this doesn't help, there may be a mechanical problem with the air transfer control flap/door that will need to be fixed.
The compressor relay is located on the compressor under a cover. Before you go to the compressor I would check for other problems that you can see and hear. If the compressor is running there is nothing wrong with its relay. 1. Check the condenser and make sure it is clear and free of dust. 2. If the compressor is cool or cold check for a bad temperature control. 3. Check the freezer compartment for frost on back wall.
