Evap coil freezes at top next to defrost thermostat

Sounds like you may have a restriction or blockage, may also be low on freon

SOURCE: Evaporator coils icing up

Hi Jijm,

The time is really fast for the Evaporator to be freezing up like Sparkgap said. A possible solution is that you Defrost heater is burned out. It is usually located at the bottom of the evaporator encased inside a Glass Tube with a wire connected to both ends. If you have already accessed the Evaporator coils look for this heatrer and remove it for examination. What I find is the heater is usually burned in two. You can use a Volt ohm meter to check the resistance across the two connections, It should read less than 20 ohms. You can get another heater at www.repairclinic.com. Since you are icing up so fast, you might have your thermostat for the freezer set to wide open making it run all the time to gain the coldest temp possible. Please do not knock what Sparkgap said as you could have some moist air getting into your freezer through the door seals. If your heater is ok, then it may be the Defrost temperature sensor. This is unlikely, but still possible. I am not familiar with the Amana fridge so I am not sure where this sensor is located. It does have to be somewhere around the evap coils.

check continuity thro the fan motor and check it rotates freely

SOURCE: Refrigerator section on side by side losing cooling

Here is the Amana website with the manuals which should show you where the defrost timer etc. is located. Witht your model number and manual it will be a lot easer

And yes the defrost timer thermostat and heater are the most likely problem.

Do not let this keep running and running or you may lose your compressor too which means a lot more expense than now.

Your not going into defrost, the fridge cycles into defrost every 8-10hrs for approx 20mins....problem could be multile items, the defrost time, defrost thermostat, or the defrost heater, will need a meter to ohm heater and thermostat...thermostat will be a closed circuit when it gets below 22degrees. ohm the heater out...if both check ok, will be a timer issue. Can do a simpler check....in the fridge section near controls there is a smal hole with a gear on the inside....that is your defrost timer. take a falt tip screwdriver and turn that gear until it clicks, this will put the fridge into defrost...if everything on the heater side is ok you will hear a sizzle from the ice melting
