Question about Amana AFD2535DES French Door Refrigerator

1 Answer

How do I test the defrost thermostat?

The evaporator fan will not run...tested the fan > works, tested the freezer light switch > works. If I connect the defrost thermostat wires together should the fan immediately start running if the thermostat is faulty?

I'm down to the thermostat or the jazz board and I want to make sure I'm not missing something before I buy the jazz board.

Thanks in advance for any help.

Hi.

When the back of the freezer is icing up you need to test the defrost system, which is responsible for the problem . The evaporator coils freeze up because the defrost system is not working. this results in compressor and fan running most of the time and in reduced or no cooling, particularly in the fresh food section. The freezer may still be cooling.

Defrost system problems are quite a common issue with refrigerators. Coils freeze because of a defective defrost system. With coils frozen the condenser will go under stress and will loose efficiency. The result is the system not producing enough cold to refrigerate the fresh food section while the freezer section instead keeps working.

Try disconnecting power overnight. Allow the freezer to defrost with power off. If the fridge works after that you have a defective defrost system. In that case the problem may come back after a couple of days. To fix the problem the parts comprised in defrost system must be tested, so to find and replace the defective part.

The defrost system comprises defrost thermostat, heater, defrost control and fan. The parts that fail more commonly are thermostat and heater. Both parts are located behind freezer firewall and tested reading impedance with a multimeter. Element and thermostat are faulty if they return Ohms infinity (the circuit is open) when reading impedance with a multimeter at the part's contact.

If thermostat and element are OK, the next part to be tested is the fan. Fan can be tested by simply checking that the motor is running when energized.

Here a tip explaining how to deal with a similar problem on a different fridge model: Fridge not cooling. Procedure is similar with your model.

Here all parts and diagrams for your model.

Ice develops at back of fridge


hi chris
dave here hope i can help

I would test the defrost timer, defrost heater or defrost limit switch

TESTING AND REPLACING THE DEFROST TIMER
This timer activates the heater that melts frost in the evaporator for 10 to 20 minutes every 10 to 12 hours. In the process, it turns the compressor off and on. If it fails, the compressor may not run. Or the heater may not go on, eventually causing a hidden ice buildup that blocks the cold-air flow and disables the evaporator fan. An access hole lets you test the timer. If the timer isn't in the control panel, look behind the front grille or behind the rear access panel. If the compressor fails to run turn the timer until it clicks. If compressor goes on, timer is faulty. If unit isn't defrosting automatically and turning timer stops compressor or fan, timer is faulty.
Before replacing timer, spray it with electrical contact cleaner through access hole and turn it a few times. Stop just before a click and wait to see if timer advances on its own.
To replace timer, unplug the refrigerator and open control panel. Remove screws holding timer to panel and pull of leads. If wires aren't in a plug, move then one at a time to new timer.

EVAPORATOR AND DEFROST HEATER
In a frost-free unit, the evaporator coils, their fan, and the deforst heater are located behind the freezer's back wall or under its floor. The fan, which circulates cold air between the coils and the two food compartments, is controlled by the door switch, the thermostat, or both. To check the fan, open both doors, wait for the compressor to go on, and hold in the door switch. If you can't hear the fan running, test the fan(below).
The defrost heater, which melts frost on the coils, is cycled on by the defrost timer(above). If the frost melts before the end of the defrost cycle, the defrost limit switch turns the heater off. The heater may be a metal rod, a wire wrapped in foil, or a coil inside a glass tube. All are tested the same way. Test terminals for the heater are often located in the control panel or under a doorjamb; check the wiring diagram. Or test the heater leads inside the evaporator compartment.

TESTING THE EVAPORATOR FAN
To remove the evaporator fan, unplug unit; open back panel(or floor) of freezer. Then unscrew housing holding fan, and take off leads going to fan motor. With VOM(Volt-Ohm Meter) on RX1, probe motor terminals(except green ground wire terminal). Look for moderate resistance(50 to 200 ohms). Replace fan if much lower or infinity.

TESTING THE DEFROST HEATER
Open control panel. With VOM on RX1, probe test terminals. Look for 15-to 100-ohm reading. If infinity, turn defrost timer(as above); retest.

TESTING DEFROST LIMIT SWITCH
Trace and disconnect leads. With VOM on RX1, probe leads. Look for infinity reading when switch is warm, zero after 20 minutes in working freezer.

Hope this sources your problem

My refrigerator is not cooling but the freezer is cooling?


This is an indication that either your defrost heater or defrost thermostat may not be working. A failed evaporator would produce the same effect. You need to test your defrost heater and if it is good replace the defrost thermostat. Do not forget to check your evaporator fan. If it is not running, you need to replace it provided that ice has not built up on the back plate of your freezer.

P.S. Ice building up in the freezer backplate is an indication that defrost heater is not working.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

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.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

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.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

I have a cold freezer/warm fridge problem


Hi, Yes, They are the same thing. Can you hear the fan motor running in the freezer? If not it probably needs replaced. Some units shut the fan off by a door switch. If its not running when the door is closed, it could be the door switch. If the fan is ok, make sure the thermostat is set right. Sometimes something in the frige gets bumped against it and it will get moved. NOTE: Allow aprox 12-24 hours for changes in thermostat settings to take full effect. If this all checks out ok I would suspect the defrost timer. Remove everything and place in coolers or another refrigerator. Unplug the refrigerator. With doors open let it sit for aprox 6 hrs. A fan blowing into the freezer section will help. Plug back in and see if it works good again. If it works good for a couple of days and problem returns, Replace the defrost timer. Hope this helps. kstfas
