Check the door switches and see if they are engaging when the doors are shut. they are mounted just above each door. If just one is not being pressed in it will keep all of the inside fans off. also there is afan delay mounted by the inside coil that will keep the fans off until the coill cools to a certain set point to prevent recirculating hot air. depending on conditions it may take the fans a good 15 minutes to come on ,or longer in a very hot start up.

RF267aewp french door refrigerator is acting crazy. Sometimes compressor fan runs, sometimes it doesn't same with freezer fans. Front control panel will not respond so I cannot get into diagno


Had same problem on my fridge a long time ago. Here is what was wrong on mine. Debris had clogged up around the fan blades to the point where the very small motor that runs the fan was not powerful enough to make the fan turn. When this happens the compressor has to work harder and harder until it finally shut down on safety cutout. I had to open the back of the fridge and clean up the fan blades, [ took the opportunity to put a small amount of oil on the fan shaft too, my Norge fridge is now over 50 years old.]

My true gdm-43f freezer keeps running won


Not sure exactly what the situation is I'm going to give you a detailed overview on how the system works that way you'll be able to isolate the problem. Your machine is a single compressor unit, meaning that even though there are two seperate sides, the freezer and the refridgerator, they do not operate independantly. The sealed system, which is what cools the machine, has two parts, a high side and a low side. The high side is located under the machine and consist of a condensor, for which freon is pressurized back into a liquid and passed throug the compresoor to be released as a gas into the evaperator, the low side. This is where the freon is at a cold state. Ok, now that you have the bare basics of a sealed system, we move forward. The Evaporator is located in the freezer side, behind the freezer wall. As freon goes through the evaporator, a fan, called the evaporator fan, is located above it and circulates air throughout the freezer compartment. Also, an airway connects the freezer to the refridgerator, usually top right of freezer, or top left refridgerator on side by sides and through the freezer floor on top mount models. This means the freezer cools the refridgerator side. ****First check point**** Is the fan running in the freezer? This would cause the freezer not to cool as well but also a rise in the refrigeration side would be noticed. As freon goes throught the evaporator, which is made of aluminum, the temperature levels are well below the freezing point, so frost and ice will form on the coils. Over time, this kind of build up would form a blockage, not letting air be drawn from the bottom of the coils by the fan to circulate the cold air. To prevent this from happening the a defrost heater is installed to thaw the ice away and comes on every 6-8 hours. This is initiated by the defrost timer, or in some machines an adaptive defrost control. The heater will be located at the bottom of the evaporator because hot air rises, getting maximum effect. A third part to the defrost system, the first two being the timer and heater, is a bi-metal,or terminating thermost. Its called this because when the thermostat is cold, the metal inside it constricts making a pathway for electricity to flow through to the defrost heaters so it can get hot, and as the heat rises and the ice melts away, the terminating thermostat will warm up, and the metal will expand causing the path of electricity to be broken, turing the heaters off. This is to prevent any high temperature situation from happening, like melting plastic or even a fire. If any of these parts fail, the machine will nit defrost. ***Checkpoint two***** Do you see any ice build up on the freezer wall. This ice will be completely across the back wall. Most signs of defrost problems are noticed first by a rise in temperature on the refrigerator side first. The above can be assessed with a quick look and listen. If no frost is present and the fan is running you can rule out the above. ****Please not that ice build up on just a small section, for example, upper left or right corner only is not a defrost situation but a sealed system issue, caused from low freon or a restriction in the lines and a EPA certified technician should be called.****** The last thing you should check you'll need to pull the machine away from the wall and remove the lower panel to gain access to the compressor area. What you are checking here is to see if the condensor fan motor is running and that the coils are somewhat clean enough for air to flow across them. The fan draws air from across the compressor and through the coils helping to keep the compressor temperature down and also to evaporate the water that is drain when the machine goes into defrost. Rule of thumb is if the compressor is on the fan should be. If the fan isn't runnning the heat from the compressor will be transferred to the machine and notice first on the freezer more so than the refrigerator. ****checkpoint three**** IS the condensor fan running? Are the coils clean, and can you feel the air from the fan with your hand placed on the opposite side of the coils?
The refrigerator side is usually where your defrost timer, discussed earlier is located. Also on this side is where your temperature control, or controls , are located, These controls are what are called thermostats, and have a direct line to the compressor. This means when the temperature has reached the desired setting the thermostat will kill power to the compressor in the same manner the terminating thermostat does with the defrost heater. Some models have a temperature control thermostat for the freezer and the refrigeratot, but some only for the refrigerator. The most noticeable sign of a thermostat being bad is the food in the refrigerator side will freeze, usually on any setting or the machine won't come on at all, including the fans. Problems are usually noticed on the refrigeratot side first. The last thing to discuss is The freezer and the refrigerator both are rising in temperature, but the fans are running, etc. Normally in cases like this a humming sound followed by click is heard or sometimes just the click. The humming sound is the compressor trying to start but failing and the click is the relay breaking contact. On newer machines, especially ones that fall under the whirlpool umbrella, the compressor relay, also called the start device has failed and needs to be replaced, but also the compressor itself could be bad. Well, thats the basics. I know it's long winded but I wanted to put something that you could print out and use as reference. Good luck.

Freezer is too warm. We have cleaned all vents but is still in the 40s


Hello,

Compressor is one reason why your freezer may not get cold. The compressor which is usually found at the back of the freezer helps to pump out gas/ cold air and the fan circulates this cold air in the freezer. If this compressor is knocked/defective, the freezer won't cool. Also, gas in the compressor sometimes get's finished and needs to be refilled. So, the compressor needs to be checked in a situation like this.

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster.

I hope the above helps.....

For further assistance, please let me know.

My freezer does not work all of the time. I HAVE NOTICED that the freezer get very hot at the top of the unit, I have measured this with a digital therm.and temperture was reading 136 degree F. and,the...


The first thing to check is the condenser coil at the bottom of the freezer. Take the slatted front cover off at the bottom where the compressor is located. You will see the conderser coils. This looks like a radiator with aluminum fins, about 16 by 16 inches square. Be sure the coils are clean. Since the compressor is close to the floor it pulls a lot of dust into the coils. You may need to take a long stiff bristle brush to get as much dust as possible off the coils. If this is stopped up, the unit will definately overheat very quickly. While you are down there make sure the fan behind the coils is running. There are several reasons the fan might stop running. The motor can burn out, something can impede the fan blades such as paper, or sometimes rodents. If the fan isn't running the compressor will overheat and shut off. Once you check these basic things, you may then have to address the problem of dissapating the heat. The answer to your question is yes, it will shut down if it gets too hot. You need plenty of air space behind and over the unit in your situation. The air needs to flow into the front bottom section of this unit and flow freely out the back. All commercial refrigeration is designed to operate in 75 degree areas. As your room temperature increases the efficiency of the freezer will decrease. It is not uncommon to find these units in kitchens where the temperature is 85 even 90 degrees. They will continue to work, but will probably run all the time. I would think if you could get 3 to 4 inches of space at the back of the unit and the two feet above the unit with clean coils and properly running fans, you should get better results. You MUST have free flowing air to keep the unit running. The ideal situation is to have the air flow directly through from front to the back of the compressor compartment. In your case, you may have to move the freezer away from the back wall and allow the air to flow up the back of the freezer and out over the top into the room. 2 inch holes are not enough.
