The coil of my majic chef refrigerator was not defrosting and frozen all over.
I have manual defrosted it several times and it works for a short, like a month.
After a month of not running at all, it started running again for about a week. Then quit again.
Now it stopped running all together. I am getting ready to look for a reset for the compressor.
And also how to check them defrost unit part.

Re: the coil of my majic chef refridgrator was not
Hi, To be honest, you won't find a reset button on the compressor or anywhere else. If the freezer was icing up on you, more then likely you have a defrost timer that is going or has failed you. Normally located at the back on the bottom. You should have a fiber panel you can remove to get to it, the condenser fan motor and the compressor. Make sure you have power to the unit that it hasn't tripped the breaker. If not, make sure the condensers coil is clean in the front, and the motor runs when the thermostat is set for the unit to be on. Make sure of this. If the compressor is not on and the motor is on, you have a problem in the compressor. A faulty external overload protector, or it could be locked up with a locked rotor. Make sure the fan in the freezer is on, the evaporator fan. On the defrost timer is a screwdriver slot you can turn in the direction the arrow says, just a notch to see if it comes on and runs. If it does, the timer needs replaced as the timer motor or clock is faulty if it comes on manually. Check all of these things and keep me posted. Shastalaker7

You have either a defrost timer, defrost thermostat or defrost element that is bad.Before you defrost, use an ohmmeter to check the defrost thermostat to see if it is closed. If it is , defrost and check the defrost element for continuity. If it has verry little resistance , you have a bad defrost timer.
Is this a two door refrigerator?
If it is then their is an air duct that allows some air from the freezer to cool the fridge section.
Three things to look for;
Is the air duct blocked
Is the fan blowing air
is the freezer coil frozen over.
Try manually defrosting the fridge. If that helps then you have an auto defrost problem. A technician can help you there
twist your defrost timer with a screwdriver clocwise till it will click and compressor shut off, check voltage on defrost heater. You should have 120volts.When wait 20 min if compressor start up back and defrost heater is off ...your timer is fine. It can come on early then 20 min....
P.S. defrost heater located on the bottom of the coil, also make sure your defrost thermostat is frozen when you going to check voltage on your heater. Thermostat located on the top of your coil.
Defrost circuit failed, needs to be able to defrost the coils so air can pass through them thus cooling evenly. You can check the heaters located on the coils probably near the bottom back wall of the freezer with a ohm meter if you read through, the heaters are good, if you get no reading the heaters are bad. Or could be defrost timer or on newer models the adaptive defrost control which is a circuit board. If its an older model you can manually turn the timer with a screwdriver if you feel resistance, then you should replace the timer. Also in the circuit is the defrost thermostat located on the coils, this is the least expensive of the 3 components to replace. You should have a schematic located under the fridge, use this to determine which type of timer you have and for further trouble-shooting. Please let me know if this helps
If freezer is icing up, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow. You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model
Sounds like a defrost problem. Check to see if
there is any frost buildup in the back wall of the freezer. If so, it is not
defrosting as it should.
bad defrost timer
bad defrost heater (in freezer)
bad thermo switch in freezer
you don’t know what these are then unplug the machine and let the ice melt in
the freezer overnight with the door open. Then try it the next day, if is
cooling fine then you need to have a service person replace one of the above
items. If it still has a problem then it might be the compressor and you should
probably replace the machine.
At the back bottom of the freezer there is a drain. It is frozen. Remove the rear bottom panel in the freezer. Break up the ice (I use a small putty knife) and get all of it out including the ice on the bottom of the freezer floor. Run HOT water over the drain until it drains freely to the pan underneath and your problem is solved. Whirlpool makes a heat probe that connects to the defrost heater and sticks down into the drain hole that helps prevent this from happening again. The part # is 819043 ($9-$13). The heat probe is about 4-5 inches long so it depends on how close the defrost heater is to the drain hole. If you look at this diagram the defrost heater is # 12. I have seen people use a metal clothes hanger as a substitute but hanger must be tight around heater. This keeps that drain hole warm. Let me know if you have any other questions.
