Check the defrost timer for operation if your unit has one. Some Delfield models have solid state controls. If your system has a timer for the defrost you can open the timer cover and turn the dial in the direction indicated by the arrow until a time peg comes up to the time of day marker. You will hear a loud click and the compressor will shut off. Defrost should take place. The inner dial of the timer will have some indication as to how long in minutes the defrost should take. If the pointer does not move while in the defrost position the timer motor is bad. Turn the dial again so the copper pointer goes past the time of day marker and the compressor should restart. Replace the timer.

    The fans normally shut off when the door is opened . At times the door will not contact one of the fan light switches to turn on the fans when you close the door(s). With the door open push in on the switch and see if the fans operate.

    For the defrost; when in defrost there are two items that come into play. The defrost heaters and a defrost termination switch. If the defrost termination switch is defective the freezer coil will not defrost and the same if the heater is open.

    You actually have two separate problems from your description.

Why mu refrigerator rrtg21pabb ia working but not freeze
If the refrigerator is not defrosting, the defrost control board might be defective. The defrost control board monitors several conditions and determines how often to run the defrost cycle. If the board fails, the refrigerator will not go into the defrost cycle. Eventually, ice will build up on the evaporator coil and then the refrigerator and or freezer will not stay cold enough. This will depend on where the evaporator is located. It's prudent to check the defrost heater and defrost thermostat for continuity before replacing the defrost control board.

This is normal. All commercfial freezers must defrost 3 to 5 times a day, or they will freeze over at the coil and then stop freezing. A timer in your freezer turns off the compressor and turns a heating element on for 10 to 15 minutes. During that time the coil heats and melts frost from the coil. Usually within 30 minutes the temperature will briefly rise to 20 t0 25 degrees F and then quickly drop down to 0 degrees F. The food rarely defrosts in this short period of time..

check your door seals. warm air leaking in can keep it from reaching it's temp. also, the condensation will collect on the evaporator coils causing them to freeze up. when they do, there is no air flow to cool the rest of the fridge, so the compressor will run constantly trying to reach the set temp. empty it out, thaw out the coils, and check your door seals for leaks. if it still happens, you might have a slow freon leak.

The freezer will not freeze or keep its
Check to condenser coil and make sure it is clean and the fan near it is running when the compressor is on. Check for ice build up in the freezer. If the evaporator coil is iced up the box will run warm. It may be a defrost problem, a dirty condenser, or a refrigerant issue.

Not sure of your model number and manufacturer, but in some freezer there is a seperate drain heater that should stay on for the complete defrost time. (the defrost heater will shut off when the evap coil reaches a certain temp, and the rest of the defrost time only the drain heater is energized.) That would be the very first place that I would start. Hope this helps

We have a true T49F freezer and the evaporator fans are not running. The compressor is running on startup. The coils are cold. But are freezing up. Shouldn't the fan be on, or does the cabinet have to...
Freezers have a sensor that is referred to as a "Fan Delay/Defrost Terminator". It senses the temp during the defrost cycle. Usually, when the evap temp reaches about 50 degrees, there should not be any frost or ice on it. This device terminates the defrost cycle. It also keeps the fans off so warm air is not circulated. When the evap gets to about 20 degress or so, the sensor switches on the evap fans. If the fans are not coming on, either the sensor is bad or the evap is not reaching the proper temp to cause the sensor to turn on the fans.

Hope is helps to clear up some things and point you in a direction as to what might be going on.

Freezer won't keep the sane Temp
Check that the fanmotor is running and is not obstructed. If it is running, then you have an ice build up on the freezer (evaporator) coils. This can be caused by failure of the defrost system. Either the control board needs replacing or the defrost element, or the thermodisc.

Proper temp. range in freezer
Hi dgh1,
The freezer should stay within 5 degrees of 0 while in operation. While in defrost the freezer may reach as high as 20 to 25 degrees. If any higher temperatures are reached your food will spoil as they are defrosted and refroze everyday. If you find that the temperature is allowing your food to defrost you may want to replace your defrost thermostat. This device is located on top of the evaperator coil inside the back of the freezer. It is made to turn the heater off when a temperature of 55 degrees is reached. One other possible problem could be your defrost timer is taking to long to restart the cooling cycle after defrosting. I hope this will help you and please send any other questions you may have, I am happy to help. and dont forget to rate me.

Kenmore frostless 19 temp. control knob
i've pulled up the service diagram for it and there's no thermostat or temperature control but there's a limit sensor inside the freezer I'm sure that such sensor is failing and when it defrosts, it stays on to long, and the whole 15 min defrost cycles goes on causing the freezer to warm up, delaying the freezing process. I'm almost sure that the limit is going.
