    The Evap. coil has light ice film, looks ok. As I said, I replaced the evaporator fan because it is not running. Therefore, the refg. side is not cold. Compressor is running, no fan.I thought it was supposed to run all the time. Is it in an "OFF" cycle, or is it the defrost timer?

    This Refg. has a circuit board. The vent on Refg. side is open. Thanks, for your help..Happy Holidays!

    Compressor is running,ice on coils ok, evaporator fan still

    does not work.. Thanks!

    Will a bad defrost control board (12050506) keep the Evap. fan from running.Thanks!

First, I think it’s important to know that the Ref side has no cooling coils, it’s basically a box and the cold air in the freezer is blown over by a fan through a channel into the Ref side. This channel has a door which regulates how much cold air goes through. You probably have two control knobs in the Ref side, one controls the temp with numbers 1-9, 9 being the coldest. This temp control tells the compressor how long to run. The other control is for that little door and it may have letters A-E, E being the coldest. If you set it on E (coldest) then this will close that little door and keep most the cold air in the freezer.

Now, why is that cold air not getting over to the Ref side?
1. The little door is not open.
check your control setting. You can't see the door but, you should be able to feel air coming through the channel on the Ref side.

2. The fan in the freezer is not working.
You can hear this fan running when you open the freezer.

3. The coils on the freezer side are clogged with ice which won't let the fan circulate the air over to the Ref side.
This is a failure of the defrost system which consist of the defrost timer, heater, and thermo disc.

Also, If you replaced the evaporator fan then you got a good look at the cooling coils. Look at these coils while it is running. There should be a light coat of frost on all the coils. If this frost line is only 3/4 or 1/2 or any amount less than full coverage of the coils then the system has a coolant leak.

Directly under these coils is the drain pan and drain hole in the middle. This area should be clear of any ice or debris.

    When the defrost timer goes into the defrost mode it will cut off the evaporator fan, compressor, and condenser fan. If the compressor is running then the evaporator fan should be running.

    Sorry for the late reply we've been out of town. Yes, but I would check the schematic drawing to see where the power to the fan comes from to make sure there is not a break somewhere else.

A amana French door fridge no fan water or.icemaker lights come on but no fan turning on or cold


Many Amana model fridges have the freezer fan wired through the bi-metal thermostat that is clipped to the evaporator. Either your compressor has a bad start device and that is why it is not cooling, or the compressor IS running and the unit has lost its refrigerant charge. Running compressor with no cooling = buy a new fridge.
Compressor hot, but not running = start relay replacement to get the compressor going. Start Device 8201786

No power to freezer fan on hotpoint ffa91


On some of theses units the fans are connected through the defrost bi metal. When the bi metal gets cold the fan comes on. Check and replace bi metal. Should solve your issue.

The refrigerator isn't getting cold, the freezer works fine, but this morning there was a stream of water on the floor. it seems when its hot out is when I have problems with it.


The first thing you want to do is open the freezer and see if the fan inside there is running. The reason is the freezer cools the refrigerator side by circulating air from the freezer. If the fan is running then your problem is one or more parts of the defrost system is malfunctioned and in return your problem arises. There are three parts to the system, the defrost timer or in some cases control board, defrost thermostat also known as a bi-metal, and the defrost heater. The defrost system is set up to operate as so. The defrost timer or control board will turn the machine off, in some cases every 8 hours, some 12. During this time period the defrost heaters, located behind the freezer wall and rest underneath the evaporator, yet wires to them run up the side of it, are energized and emit heat that raises upward to melt the ice that has formed on the evaporator coils. The bi-metal or defrost thermostat is at the top of the evaporator. When the heat from the heater starts to reach the bi-metal, it breaks the circuit turning the heater off. The whole purpose of this is because the freezer cool the refridgerator side by drawing air across the coils and blowing to the other side via the evap fan motor. In my opinion, if you change one part of the defrost system change them all because usually when one part fails another will follow, so save yourself the time and the food loss, the cost difference is minute.

Refrigerator purchased March 2008, model # 59665969700, freezer on bottom. Refrigerator stops being cold. Freezer seems to get colder, icing up on back interior.


That icing up on back interior im assuming is in the freezer. If its a layer of frost, you have a defrost problem, and should check continuity through the defrost heater and the bi metal thermostat, both located on the evaporator coil behind the back wall of the freezer. If either fail, replace, if both of those pass the check, then your defrost control is failing to switch into defrost and needs to be replaced. If the icing up is like frozen sweat drips on the back wall, replace the evaporator fan motor.

Refrigerator not cold, freezer barely cold and has ice on back wall


You have a defrost problem if the ice is on the back lower wall of the freezer section.... This is where the evaporator is located just under a fan.(aluminum coils looks like a radiator) There are three parts to the automatic defrost system- the heating element(found at the bottom of the evaporator) a bi-metal thermostat(found at the top of the evaporator) and a defrost control board(usually in the top of the refrigerator section,but this varies)

If you take off the back freezer panel and melt the ice build- up with a hair dryer or letting it open overnight, without poking any holes in evaporator and losing freon(out a fridge) your fridge will run fine for about 3 weeks. This is humidity from air collecting, automatic defrost system usually works about every 8 hours when working normally. Your sealed system and compressor are fine, you have a defrost problem. Good luck.

Doesnt get cold??


Okay,
Defective compressor, refrigerant low from a leak in the system, dirty condenser coils, condenser fan not working, bad compressor relay or capacitor, main thermostat control not working, thermostat needs to be set at proper setting, frozen evaporator coils do to faulty defrost timer, defrost heater coil broken, or the defrost determination thermostat has stayed in the open position, which would result in no defrost and the ice blockage would stop air the circulation, defective evaporator fan, defective door switch which controls the evaporator fan when one opens and closes the freezer door. Freezer drain clogged which would possibly cause the fan to be stuck because of ice built up around it.

Refrigerator motor is still running but it isn't as cold as it should be. Is there something that I need to change?


Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

How to check stuff>
http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php
Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

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).
If the evaporator coils behind the back panel of the freezer are icing up heavy because of auto defrost failure that will stop the circulation of cold air
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.
