Question about Amana Freezers
Freezer won't freeze, fan
Check to see if there is any frost buildup in
the back wall of the freezer. If so, it is not defrosting as it should.

remove the rear cover inside the freezer if it has a lot of frost on it,then the evaporator coil is frozen up and you cant blow cold air over or thru a solid block of ice,defrost it,then check the defrost heating element,defrost thermostat and timer or defrost circuitry for no power or defective components,you can use a hand held hair dryer to defrost it quicker

Hi and welcome to FixYa, I am Kelly.
There are 12 midelos that fall under the model number you passed. I will cite EV171NYMQ05 as a reference model number via this link:
The freezer fan should be on anytime the compressor is on. If there is an ice block built up on the evaporator coils it can lock the fan blade in place via the ice build up. Additionally... if the fan motor bearings are dry or coated with sludge this too can prevent the fan motor from operating. The fan motor is item 3 this link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769&diagram_id=28174432#d28174432
To check the can motor all that is required is a simple continuity check across the 2 connector wires. You should read under 480 ohms.
If you discover that the fan blades are encased in ice... do a manual defrost: (be ready to tend to a water mess)
1. By first unplugging the unit and then removing the freezer contents.
2. Direct an external fan into the freezer compartment for just over 2 hours.
3. Make sure the compartement drain funnel is clear of obstructions. Item 11 this link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769&diagram_id=28158051#d28158051
After the 2 hour manual defrost period plug in the unit and test to see if the fan motor is running.
If it is running you may have an automatic defrost problem causing the ice build up. On a freezer the ice build up will start again if there is an automatic defrost problem in 3 - 5 days. Until the automatic defrost problem is corrected you will end up doing the manual defrost routine described above everytime you have improper cooling problems.
Components that can cause the automatic defrosting problems are
1. The defrost timer item 7 this link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769&diagram_id=28257341#d28257341 Because it is not cycling or stuck in one position.
2. The defrost bi-metal thermostat item 9 above link (stuck closed)
3. The defrost heating element item 5 above link. (open)
And of course internal wiring....
Check the fan motor for continuity... if you attempt to lubricate it which is very difficult on this fan motor make sure you use paraffin based "Turbine oil" and not a regular household or automotive oil. Using any other oil will cause the fan to stop working in as little as 30 days.
Thanks for choosing FixYa,
