I own a Maytag Atlantic that is only blowing cold air no matter what cycle I set it in also when I open the door the light is not turning on, could this be related and what the causes may be?

Some things to start with. Defroster not working and evaporator is iced over. Fan that circulates air has failed. Solenoid on flapper that opens air passage is not opening.

A fridge makes cold air in the freezer only and blows it into the fridge throu a little air door with a small fan, one of your temerature adjustments will open and close this little door and the other ajustment (the thrmostate) will turn on and off the compressor at what ever temperature you have it set for. if the little door is closed to much the cold air can not get into the fridge fast enough to make the temperature cold enough to turn of the thermostate. This will cause items to freeze near the air door as the air comming out of it will be something like -20C. to fix this it sometimes helps to open this little door more... something like "freezer temp warmer" and also to turn the "fridge temp warmer". if that does not do it, then the thermostate may be faulty, to test it slowly turn it down untill the fridge turns off, if it only turns off at the off position, replace it. also one last thing , sometimes the airdoor can frost up and restrict the air from blowing into the fridge, so you can unplug the fridge and leave the doors open for the weekend and let everything thaw out. then set all the controls for normal and plug back in. Make sure you do not leave the unit plugged in or sometimes the little door light can get so hot it may melt the plastic lining in the fridge.

Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

your blend door motor is stuck or it may need to be replaced. the blend door controls the temp from heat to a/c

try keeping the freezer door shut while felling for cold air blowing over to refrigerator side..if so problem lies in the thermostat...its not sensing the correct temp for the fridge side and closing the damper too early...also check to see if there is frost built up on the back wall of the freezer section if thats the case then you are at the begining stages of a defrost issue and soon no cold air will blow over to fridge side..let me know what you find

if you can hear the fan still blowing but no cold air coming up to fridge section a common problem with bottom mount freezers is the door gets left open and the air ducts freeze up and the air can't blow up to the top.turn the control off in the freezer.remove the top shelf and the door,check to see if there are any screws one on each side of the slide arms,if there are remove them and lift the door up and out,with a hair dryer melt out the ice by blowing the hot air up each side of the back wall,also if the back inside wall of the freezer is covered with ice or like snow then you have a defrost problem but if there's no ice on back wall do what i said and blow the air up the sides of the back wall through the vents until no more water is seen dripping through the vent holes,then turn the freezer back on and check to see if you feel cold air blowing in through the vents in the fridge section,if you feel cold air then you're all set,if not keep blowing the hot air up the sides until it's melted out.let me know what you find,you'll know if the door was left open,ice will be on the ceiling near the light switch and sometimes on the top of the freezer door

1.)If your System is OVERCHARGED this Will Occure due to the EVAPERATOR FREEZING UP
2.) Also if your HVAC Control Modual is Malfunctioning this will Aslo Cause this Condition, It Controls the BLEND DOORS that OPEN for COLD or HOT AIR Look Into these Items and Also Look Into wethrt the A/C Compressor Cycles OFF when it GETS OFF this Will POINT at the HVAC CONTROLER if it Cycles Off When Set For A/C or COLD Air

There is a door that opens to the heater core.When the vacum control in the dash gets old the diaphram gets to flimsy to close one port so it puts vacum to all ports.Therefore there is not enough pull to engage the vacum motor to move the trap door.Change the switch in the dash. Check to make sure that there isn't an obstructing object in front of the door before you buy a new switch

If you can turn it on and have the door open, hold the door switch in and see if you have a glow from the heating element. If not, your element is broken. That is if it is an electric dryer. If it is a gas dryer you need to check the pilot light or the thermo sensor.

Is 1 of the 2 AC (under the hood) lines cold? if so you may have a blend door problem, that door is in the dash air duct distribution system, it mixes are between the hot heater core and the cold AC evaporater core to give the set or desired air outlet temp, When you turn the defrost on does it blow hot/cold as the lever is moved back and forth? The compressor turning off and on is normal cycling of the system, when it reaches a preset pressure in the low side line, a pressure switch will open and compressor will "cycle off" when the press starts to rise to a preset limit the compressor will "cycle on" and so on. I assume you have an electric bled door, older cars and trucks use a cable operated mechanical door.
