Top 20 Magic Chef CTB1821AR Top Freezer Refrigerator Questions & Answers

Find and fix the refrigerant leak ( soap bubbles sometimes works). then recharge the system.

It is located in the control panel assembly in the refrigerator section at the top

Set the freezer so the temp is between 0 and -5 deg the numbers are only for reference you can start in the middle and go from there

The first thing you want to check is if the fan is running. If not thats your problem, if it is 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.

I've learned that when people say this the first thing a technician assumes is the timer, but I think that your machine isn't cold enough, more than likely because its low on freon. Check the freezer temperature, on normal settings it should be less than 5 degress F.

The drain in the freezer behind back lower panel
needs opening. You can see it at the bottom of the back panel
underneath the evaporator coils. (The cold coils)
Run Hot water in the drain until it clears or use a hairdryer.
When the defrost melts the water it goes down the drain
If the drain is clogged with Ice or ? The defrost water
overflows into the ref. or freezer or on floor

Hi

If refrigerator is not cooling properly it can be due to a defrost timer, which is causing the fridge to go into defrost cycle. Usually it takes 45-60 minutes for refrigerator to come out of defrost cycle. If the timer goes bad then it will not come out of defrost cycle and can result in this kind of issues. It can also occur due to defrost thermostat, it allows current to pass through it at temperatures of 20 to 30 degrees Fahrenheit and prevents current from passing through it at 40 to 60 degrees. This is difficult to test, though, because it takes a prolonged, very-cold temperature to turn it on. The defrost thermostat is snapped onto the top portion of the evaporator. The thermostat sends temperature information to the processor. The defrost heater must be replaced when replacing the thermostat.

1. Remove the lower fan duct work from the evaporator cover.
2. Remove the 1/4-in. evaporator cover screws and remove the evaporator cover.
3. Disconnect the defrost thermostat wiring connector.
4. Remove the defrost thermostat from the evaporator.

Hope this helps... Please post back if you need more information.

Set dials to middle setttings, if the colder /warmer dial is peffed max cold its max cold freezer!!! so move to warmer and the freezer will give more airflow to the reefer , the reefer is reliant upon the freezer for its cold air.

Hi,
Here is a tip that I wrote about the reasons why ice makers do not work.

You will have to replace the thermostat. it is faulty and is not switching the compressor off when required temp. is reached.It will be called a double door thermostat when ordering the item. There will be 3 terminals and 2 earthing points. Replace in the exact same order as you remove the wires off the faulty.one.

make sure the condenser fan is running in the back of the machine,pull it out and remove the bottom panel in the back,clean out the back with a vac and check the fan,then clean out the coil from the back and then remove the bottom kickplate in the front and vac that out.if the fan isn't running you need to replace it,that's what keeps the compressor cooled down and removes the heat from the machine.let me know what you find the fan motor part number is 63001021,in case you need it but hopefully all you'll need is a clean out

First thing is to clean the coils or grill under (or in back) of the fridge. This transfers the heat from the refrigeration unit to allow the coolant to dissipate collected or accumulated heat. If the coils are clogged with dust or other debris, it will hamper this process and waste energy.

Unplug the refrigerator.
Pull the fridge out from the wall, remove the back protective cover and vacuum everything you see. The coils may be on the bottom and you may need to get creative to clean it, but it will be worth it.

Good luck. don't forget to vote.

Set the freezer control to Warmest.(more air will go to fresh food)
Make sure the freezer fan is blowing.
Check the door seals on fresh food door especially on the bottom.(may be loose letting in warm air)
