Maybe but there is also a thermister in the defrost system that might be bad. The thermister is a small, white, barrell shape and is as big around as a pencil, It has 2 wires going in it and is attached to the top of the coils in the freezer.

SOURCE: defrost timer board for mzd2766geq

Defrost control board is in the top of the refrigerator behind the two levers that control the temperature. You have to take off the plastic cover. There are two screws and then you slide to cover to the side to remove. The board is in a white plastic housing.

The main board is located behind the unit at the lower right hand corner behind a panel that's about 8" X 12".

Samsung RB215LABP bottom Freezer shows my set temperature of -2 but maintains at -15. If I cycle power it will show the actual temperature for a while (hours). We had a power outage in a storm and it blew...


Since the defrost problem wont just go away here are details about how it works.

DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. 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 because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

How do I do a forced defrost cycle? Amana refrig afb25340deb, 12576629jj


Hello,


It sounds like you have more than the problem of the defrost cycle not keeping up with frost buildup.

The usual cause of excessive frost is that the freezer door is not fully closed, OR the gasket is not fitted properly, OR the gasket is worn. IF this is the problem, then when it is corrected, the normal defrost cycle timing will keep up.

Depending on the fridge, there may be a small timer for the defrost cycle, and it looks like the small, round timer motor in a dishwasher, clothes washer, and is usually located in the bottom section where the compressor is located. Often it's near the front, and if the grating at the lower front of the fridge is removed you can find it.

The timer [if your fridge uses this type, versus some solid state timing device built into a circuit board] will usually have a small plastic "shaft" / knob sticking out of the center. Rotating this shaft clockwise should advance the time when the defrost cycle begins.

IT DOES NOT, REPEAT DOES NOT, shorten the time BETWEEN cycles, only ADVANCES the "clock." You will have to readjust each time you want to accelerate the defrost start.

Good luck and hope this helpout.....

Running to cold, after while evaporator coils are packed with ice even defrost timer ,termostat and heaters are new.


Hello, Most likely you have a bad defrost timer, If you have a mechanical defrost timer it will normally be located either in the control panel inside the fridge or behind the panel beneath the doors. To test this once you have found the timer advance it to the defrost cycle and the wait to see if the heater makes a spitting noise. If the defrost cycle fires up then the timer is bad and you should replace it. If you have a digital defrost timer it will be a circuit board located in a panel behind the refridgerator. locate the tech sheet behind the panel under the doors and force it into the defrost cycle...once again if the defrost cycle kicks in your going to have to replace the circuit board. If you have any other questions please feel free to comment again. Mike

Freezer coils freeze up solid with ice and have to be defrosted manually


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.

Ice forming on rear of freezer wall


The best way to determine what has caused a non defrosting GE electronic control model is to first access the control board. Jump terminals line power to defrost, (J4 and J9). An amp probe should be placed on this jumper wire to determine current draw of the defrost circuit. A three amp draw is what is normal for this circuit. This will eliminate checking behind the evaporator cover to determine a defective heater or over temp device (defrost terminator). Note: This test is only to check the defrost circuit. It does not initiate a defrost cycle. If the unit is in any other cycle than defrost, that cycle will continue to operate as well.

PTS25LBM GE Profile Defrost cycle messed up


The GE Profile Refrigerator has circuit boards and sensors are in the freezer that sends a signal to the circuit board to begin and end the defrost cycle. It is very possible the sensor or the circuit board are defective and will need replaced. I will help you solve this if you like. This refrigerator is complex and will take more discussion with you to complete the repair, I am here to help, let me know, Thanks, Sea Breeze

QUESTION ABOUT DEFROST TIMER


i'm not sure what kinda timer you have there are two, one is a timer you can cycle yourself on or off the second is a defrost board does the same-thing you just can't force a defrost with it. but the way to know if it working is (defrost timer) cycle the unit in to defrost try to hear any sizzling if so your heater and defrost t-stat are ok i would replace the timer. now on the defrost board since you can't cycle it i would check the defrost element and defrost t-stat with a meter you should read a closed circuit if the heater is good, and if the coil is frosted up you should also read a closed circuit on the t-stat again replace the board. Hope this helps you

Problem in Samsung rs 2555sl Side by Side Refrigerator Troubleshooting Foru


Look at the link attached, the defrost t-stat is #38 (thermo bimetal). Clips to the coil, looks like a round device with wires on it. Defrost t-stat is normally closed to allow power to the heat element and opens when hot enough to stop the defrost cycle. Heat element #43 should not test "open" with a multi meter, there should be some Ohm value there to show it's good. The defrost timer could be a clock type or circuit board type, page through the links diagrams and you should be able to see where it is physically located in your particular unit. http://www.partselect.com/ModelFrames.aspx?ModelID=575085&ModelNum=RS2555SL&mfgModelNum=RS2555SL&ManufactureID=1&Selected=SS50-1&Position=2&mfg=Maytag&Type=&Mark=2
