Question about Sub-Zero 736TCI Refrigerator With Ice Box

1 Answer

Freezer is Iced over. Maybe the condenser is not relaying the temp. and turning off when at the proper temp?? I need to know how to defrost. I discovered the freeze when I noticed the fan making noise when ever the unit is running.

Sounds like a defrost problem.
Check Defrost heater around bottom of freezer coils.
Check Defroat Thermostat at top of coils.
This might be something that requires a service man.

Scenario:

When the defrost timer on your self defrosting unit closes, it shuts down the operation of the compressor and the evaporator fan in freezer compartment while the defrost heating element under the evaporator gets turned on to defrost the ice buildup in freezer. A defrost thermostat attached to the evaporator coil will turn off the defrost heating element if it gets too warm. Then when the defrost timer opens, the compressor and evaporator fan get turned back on for normal cooling cycles via the thermostat.. The defrost cycle lasts about a half an hour and repeats itself every 8 to 10 hours.

By the very nature of its operation you can see that in a self defrosting refrigerator, freezer temps are subject to a rather large fluctuation every time the self defroster goes on. Ergo, frozen food in such a unit will not keep for as long as in a commercial refrigerator or chest type freezer where such a circuit does not exist, temps are constantly low, and food lasts longer. And of couse, when the freezer temps go up as a result of the heater operation it follows that refrigerator temps will also go up since cold freezer air is no longer being funnel to fridge compartment. But since the refrig temps were never as low as those of the freezer, the temp variation during the defrost cycle will be considerably smaller.

If the self defrost mechanism is not working in accordance with the description above then maybe something is wrong with the control board if you have one on your unit.

What do do if your fridge/freezer is not cold


5 reasons for fridge and/or freezer getting warm:
1- the evaporator coils are icing up and won’t let air circulate.
2- the evaporator fan is not working to circulate air.
3- there is no refrigerant in the system.
4- no power to fridge or compressor.
5- the condenser coils have no air circulation

check under the fridge behind the vent. if it is too dusty or the fan isn’t working, it is not getting enough airflow to cool down. replace fan and/or vacuum out the dust.

if there is no power to the fridge, the light will be off. if the compressor is not running, there is a defrost timer that cuts the power temporarily to the compressor to melt ice on the coils. it’s located under the fridge behind the bottom vent. If the timer is off and the compressor is not going, the compressor or the main board is bad and needs replacing. there is also a temperature sensor on the evaporator coils that tells the defrost coil to turn on and when to turn off. if the defrost timer is on but the coil is not heating up, replace the sensor. if it still won’t heat up, it’s the timer or the coil.

the easiest way to tell if there is no refrigerant- the freezer wall is warm and the compressor is loud. if there is no refrigerant, it may be more cost effective to replace the fridge.

if you feel no air coming from the freezer vent, the fan needs replacing. If you feel air moving in the freezer but not the fridge, the channel from freezer to fridge is blocked.

if the freezer has air and the rear freezer wall has frost on it, the evaporator coils are iced up and need defrosting. causes:
1. low refrigerant
2. no fan
3. too much humid air in fridge/freezer due to door open or bad door seals
4. the condensate drain tube is clogged
5. defrost cycle not functioning properly

if the seal around the door is ripped or not completely sealing, or there is condensation at the bottom or the walls of the fridge, replace the seal(s).

no air, no fan. Replace

if the refrigerant is low, it just needs a top off. but you need to be certified by the epa to move refrigerant, so get a professional.

there defrost cycle starts with the timer. at a certain time of day for a specific time, the timer turns the compressor off and turns on the heater element located at the bottom of the evaporator coil. this stays on until the coil temp sensor reaches a certain temperature to let the timer know that the coils are defrosted and turns off the power to the element. the defrosted water drains to the condensate pan. if the timer is bad, it will never go into defrost, or never get out of it. if the element is bad, the coils will never defrost. if the temp sensor is bad, it’ll go into defrost, but it will either tell the timer that it’s always frozen or already defrosted, resulting in the element never turning on (stays frosted) or never turning off (eventually burning out the element).

Defrost timer on TFX27PF


HI SCOTT.a bit vague but i'll assume u mean it blinks but it cools for 4 days and then starts defrosting right?(temp drops u mean it gets warmer NOT colder.) well first i would check your condensing uni thoroughly.check if evaporator is iced up or not.ventilation ok.if iced up defrost all 24/48 hours and try .u could get lucky.if same again check heater and t/stat and defrost timer.if not iced up check refrigerant. fan motors. and compressor.good luck ali

My refrigerator/freezer has stopped working.


Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay. The relay is a small usually black cube shaped electrical part plugged into the compressor or wired to it nearby. It may appear burnt or rattle when shaken if it's bad. The two connections should show continuity with an amp meter. If it's good then it's most likely the compressor causing the problem.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm

Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).
If it's iced up really heavy you have an auto defrost problem. Melt the ice with a hairdryer and check the defrost system.

Freezer is not cooling properly. The controls are turned all the way to the coldest setting and the freezer is only about 25 degrees.


it sound like you need to access the evaporator unit in the freezer and see if its iced up and the defrost is working,this can be done by taking cover plate off in freezer section,if its iced up defrost it,clean condenser coils under refrigerator of dust,then turn unit on and see if it cools right again,also if it works for a while then does it again the defrost timer that power the heating coil below the evaporator coil may be bad or the element itself may be bad that defrosts the coil

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.
