My 2003 Amana Bottom Freezer Refrigerator suddenly is only blowing warm air. I had adjusted the thermostat yesterday for the first time in almost 5 years. I have vaccumed the coils underneath and the vents in the back with no improvement.

Re: Refrigerator blowing warm air.
Check the thermastat with power off remove one wire on the thermastat and read across the two terminals of the thermastat with an ohm or resistance meter if set to highest setting on the thermastat you should get a resistance reading if you don not the thermastat is vad

Look for frost on the rear of the freezer, that is a sign of a defrost problem. If the heater or heater thermostat is open then ice will form over the cols and block the flow of air. Service manual for amana bottom mount
usually when the bottomof the freezer is cold and the top isn't it's the evap fan motor isn't working and all the cold air sits at the bottom.when you open the freezer door you should hear the fan running inside the freezer,also tried to look up your model but it didn't come up.open the fridge door,look up on the right and hear the cieling and you'll see a tag with the model and serial numbers,i just need the model number and i can help you better
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp. The problem could be the electronic control if you have one or the mechanical linkages.
The auto defrost timer is faulty , you willhave to check the timer and teh corresponding circuit for worn out wires, bad thermostat or the defrost heaters. These circuits must be checked properly and the concerned spare can be tested for failure or malfunction. Even if the compressor is pumpiing too much to the bottom side freezer this can happen and stall the fcooling to the top section. Adjust the freezer temp lower and increase the blowing to the top section. Please check on all these suggestions and try. Helpful? Good day
As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...
Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...
check the fan from the freezer side if its not running /possible frozen or jammed will cause the refridge side to be warm the fan blows the freezer air into the fridge side to cool their is also a damper or duct control which can build up if no blockage or debris test fan for power if power than test fan it self if not running than repair or replace as necessary
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.

I picked up on something you wrote within your problem description. "got the thermostat replaced under warranty" & "that worked for a while ". back in Aug of 2002. It's August of 2008 and your thermostat may have failed again. 6 years later... not so unusual. Anyway, since your fridge has a bottom freezer, there must be a pass thru between the freezer and the fridge compartment in an area you haven't examined yet. The fridge gets cold air delivered from the freezer to keep it cold thru this pass thru and many fridges have an adjustable flap that allows you to limit that cold air flow. Time permitting, can you do a more thorough examination of the fridge area ( side walls near crisper drawers perhaps?) or better than that, remove the drawers and look for that air duct pass thru. Once located, if it does not have an adjustable damper, try a little duct tape to limit the amount of cold air from migrating into the fridge compartment. Other options: Can you contact Amana customer support directly and get their support? That particular model has been discontinued by Amana but they should be able to support it. Not sure I added anything to what you already know. Gave it a shot thou...
check freezer for frost build up and if FAN is blowing, check condenser, make sure its clean, and fan blowing,
check vents in refrig. make sure no blockage, controls should be in the middle setting,
make sure u didnt turn up freezer control cutting air supply to refrigertor side
should be 1/2 feel vent coming from freezer see if you feel any air coming in to refrig.
