Fridge running warmer than it should, Cooling fan on back doesn't turn, the compressor/condensor running very hot , and no new ice being made. Cleaned the cooling grid which was full of dust.

Here is the basic idea on how to keep the refrigerator, air conditioner, or vacuum cleaner to work properly. Air is moved by an electric fan or blower in order for that product to work properly. If air movement is blocked the fridge won't get cold, the central air conditioner won't cool enough, the vacume cleaner won't clean as well. Check on your fridge's air movement by inspecting the bottom of the fridge for dust and cob webs. Remove the front bottom clip-on plastic grill. Or also even access the lower back of the fridge by removeing the screws holding up the heavy cardboard cover to see inside. Blockage of air flow will prevent a fridge from getting cold. Just like a vacuum cleaner stops working when the bag is filled with dust and fibers. The air could be blocked by the accumulation of dust and fibers. Look under your fridge if it is cloged, it will look just like the stuff on a dirty central air filter.

Dust and fiber buildup blocking the fridge's air movement from back to front (or visa-versa) of your fridge will slowly (years) prevent how good it cools. The build-up of dust and cobwebs prevents your fridge from cooling (more specifically prevents the heat to disapate from the metal heat disipating fins attached to the metal tubes to be blown off by the fans air). OK! Remedy for a vacuum cleaner REPLACE THE CLOGED VACUUM BAG.

Remedy for your fridge manually REMOVE THE CLOGING DUST AND FIBERS FROM UNDER YOUR FRIDGE. SORRY fridge manufacturers do not provide a dust filter like the vacume cleaner and central air systems manufacturers do. You have to figger out the best way you can clean it. Possibly vacuum with a crevice tool, or use a small brush than vacuum. The extreme would be unplug the fridge ( so you won't get electrocuted) bring a water hose into the kitchen and spray water at cobweb buildup at the bottom fridge, than wet vac the floor then wait 20 minutes to dry before pluging the fridge back into the electric outlet.
When you stand in front of your fridge and you hear the fridge electric motor turn on, the fan will blow air.The fridge

First check the condenser fan for operation if its not running,may be shorted,stuck,etc.,replace as necessary,then if it still doesn't turn,then the mainboard in the rear in behind a cover is bad due to the fan being bad(caution:do not replace this board before making sure the fans all work,or you will immediately ruin the new mainboard,then test run for proper cooling,if still no cooling then replace the ptc overload on the compressor by unplugging it off the compressor and plugging a new replacement
