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.

Why does my maytag mqf1656tew have ice build up on bottom shelf and where is the drain plug at. This is a frost free freezer


Frost Free means that it performs defrost cycles to keep the chiller plate or evaporator fins free of frost. Difficult to know where your frost is, but it can build up on anything this time of year. If your frost is on a part that provides the cooling, then it will need a service visit as the defrost timer is faulty.

First listen inside the freezer section, and see if you hear the fan running. You may need to hold down the door switch to get the fan to come on. If you can hear the fan check the rear wall inside the freezer for frost accumulation. If you have frost you need to check the defrost system.

How do i engage defrost


"Frost free" fridges automatically cycle in and out of defrost mode a couple (or more) times a day. There is no user intervention required. If your frost free fridge is building up frost, there's a good chance that the defrost circuit has developed a problem.

before digging into the defrost circuit: If frost is building up only on a door or door opening - this is an indication of a poor freezer door seal. Once the seal is repaired or replaced, the frost should stop building up. If the frost is throughout the inside the freezer - and the temperature of the fresh food compartment and eventually the freezer is climbing - then it's more involved than a door seal.

Typical problems areas of the defrost circuit are: the defrost terminator or sensor, defrost timer assembly and defrost heating element. While the circulating fan(s) is not part of the defrost circuit - it is usually visible and should be checked when inspecting defrost heaters and terminator components in the freezer. If the fan(s) has failed or is otherwise unable to spin, it should be replaced.

If you need more help, please provide the brand and model fridge you have. Good luck!

Servis fridge / frezer not colling or freezing


i would firstly do a complete defrost- incase there has been a fault with the frost free system. if after a full defrost it runs ok then there was a fault somewhere in the defrost system including either defrost heater, cut out or possible jammed circulation fan.

Servis frost free fridge /freezer


not sure if it happens with this brand but I know others have a problem with ice build up that can interfere with the fan. If you can remove the back panel in the freezer section and take a look. If not try defrosting it for a couple of hours to see if it makes a difference.

Frige freezer


possibly due to not defrosting. take off rear panel in freezer and check if there is ice build-up on the evaporator. if so, melt off carefully with a hair dryer and appliance will then work. get back to me with what you find if you wish
