Question about Refrigerators

Freezer is not auto defrost, coils just ice up and the whole unit stops working, until I unplug it and manually defrost it. Then the unit works fine for a few weeks and it starts all over again.

Hello,

This problem occurs because each time the freezer defrosts, the defrost water is supposed to run down the inside of the freezer case and drain out through the drainline in the rear of the case - but for whatever reason, the drainline freezes and the defrost water begins to collect and freeze in the bottom of the freezer case.

The solution is to first completely empty the freezer (sorry), unplug it and remove the cover in the back of the freezer case. This is usually a full metal sheet with screws securing it to the case. If you find it in several pieces, it is probably the bottom section you need to remove.

Once you've uncovered the inner workings of your freezer, you need to locate the rather obvious defrost elements - these will usually be exposed cooper rods or tubes that heat up during each defrost cycle. Find the defrost element that is closest to the freezer's drainline, and wrap one end of the cooper wire around the defrost rod about 5 or 6 times - then run it down the inside of the rear of the freezer case, and into the drain itself, about 6 or 8 inches or more if possible.

What you have just done is to assure that each time your freezer defrost comes on, the drain water will always have a clear and unfrozen path out. Replace the cover in the back of the freezer case, and put your food back in. Plug the freezer back in. You should never have a problem with this again!

If you cannot do this all alone, i advice you get someone who can help you out in other not to complicate issues.

    The drain line never freezes. So that is not the problem.

    Hello,

    If your fridge has two sloping channels at the back wall and a hole in
    the middle this is designed to channel the water created on the defrost
    cycle through to the back of the unit where it runs onto an evaporator
    tray. This tray sits on top of the compressor and gets quite hot. The
    water simply evaporates. Sometimes this hole gets clogged up and
    prevents the water running out to this tray. The result is that water
    runs into be base of the unit. Very often the appliance will come with
    small tool for cleaning out this hole, but if not you can improvise.

    Since you said you have done the manual defrost and the problem still arise after a while, since the fault re-occurs later, this could be due to a faulty sensor, all you need do is to get someone to help you check the default sensor and to replace it.

    Take care.

    Hello,

    In many frost free fridges the ice can form all the way round the fan
    and cause it to run slowly or even seize up. This will of course result
    in the fridge or freezer not getting cold. If you hear a strange noise
    from your frost free fridge freezer which sounds like something is
    catching on a rotating fan it could be due to ice forming around it.


    If it stops working due to ice forming behind the evaporator and
    round the fan then defrosting the unit manually can fix it but it
    involves unplugging the unit for at least take 12 hours or so. You may
    not see much frost as it would be behind the back wall or behind the fan
    unit. You can’t really use a hair dryer on modern units because they
    may have a thermal fuse which protects the defrost cycle.

    Also, even
    just getting to the evaporator to defrost it can be a mammoth task
    especially with some of the new American-style fridges. If a fault
    re-occurs later it could be due to faulty sensor but if the fault was
    only due to the door been left open for a few hours accidentally then a
    total defrost could work.

    Whilst we are on with American style frost free fridge freezer’s,
    because the door’s are so big and can store so much, the opportunity to
    overload them is greater. This too causes warm air to pass into the unit
    and frost it up. Remember a frost free unit will not cope with too much
    ice on the evaporator so greater care must be taken to use it correctly
    and check the door seal’s regularly.

    Take care

    I already know this and have manually defrosted it many times. I have also checked the thing inside and out, there are no mechanical problems apairent. I think it is electrical, like maybe sensors!

  • Sulaimon Jimoh Olayemi May 16, 2010

    Hello,

    I told you before that the fault could be a sensor fault, it is possible that one of the sensors is damaged,

    since you said you have done the manual defrost and the problem still
    arise after a while, since the fault re-occurs later, this could be due
    to a faulty sensor, all you need do is to get someone to help you check
    the default sensor and get it replaced.

    Take care.

Frigidaire Fridge (frt045gm) Not Cooling Well


Bonjour,
That's not a potentiometer you turned it's the defrost timer gear knob. What you were doing is aborting the defrost cycle and allowing frost or ice to build up on the freezer coils. It built up enough to clog the airflow and the temperature in the freezer started going up. The compressor seems to be operating normally.
Follow along through a defrost cycle
To start defrost the defrost timer stops the compressor and all fans. Next it turns on the defrost heater. This melts the ice/frost off the freezer coils. The water drips down the drain line to the drain pan under the unit. If the defrost heater raises the temperature too high the defrost termination thermostat turns the heaters off. When the defrost timer times out it turns off the heaters and turns the compressor and fans back on. If the drain line clogs with food the water does not drain out and when the compressor starts again the water freezes. If this keeps happening the ice gets higher and bigger until it clogs the coils and the freezer does not get cold. If the defrost termination thermostat turns off the defrost heaters too soon all the frost is not melted from the coils. And the coils soon clog and the freezer gets too warm. If the defrost heater is bad no frost gets melted off the coils and the airflow quickly gets clogged. No defrost usually means either a bad defrost timer, a clogged drain line, a bad defrost termination thermostat or bad defrost heater. You can take a chance and replace the defrost timer. If that's the only problem your back in business. OR
If the drain line is not stopped up you can try this.
Remove all food from freezer and refrigerator, open the doors and unplug the cord. Wait 24 hours for all the frost/ice to melt. Keep the doors wide open and the cord unplugged the whole time. If the drain pan fills with water that's a good sign that the drain line is not clogged. Empty the drain pan often to keep water off the floor. After 24 hours the drain line should have stopped dripping water. If it's still dripping wait until it stops. Plug the cord back in, close the doors and wait for 1/2 cup of water to turn to ice in the freezer. Then you can put the food back in. The problem will return if the unit is not defrosting. Changing a defrost timer is not too hard. Unplug the cord. Locate the defrost timer. Take out the mounting screws and remove the part. Unplug the wires, plug them into the new part and remount it. Don't forget the ground wire if it has one.
Plug the cord back in and see what happens. If you did not defrost the unit turn that timer knob very very very slowly until you hear the compressor stop. Then wait to see if the drain line is dripping water into the drain pan. If it is your in business. If not either the drain line is clogged, the defrost heater is burned out or the defrost termination thermostat is bad and has the defrost heater shut off.
OR Or you can call a service technician.

Refrigerator stopped cooling. As close as I can tell the fan in the freezer part was frosted up for a length of time and has possibly ruined the fridges cooling fan? Kenmore model 106 freezer on top.


If the fan in the freezer stops, then coll air from freezer will not pass from freezer section to fridge section.In that case, the freezer section will get over frosted but fridge section will not get cold, because cool air will not pass from freezer to fridge.The fan is there for two things, 1) for cooling the heating evaporator coil and 2) For flowing the cool air from freezer to fridge.---------- If the frost is getting collected and fan is getting stuck up in frost, then this is the problem.The defrost cycle is not running, the cooling cycle is running.---------------
This problem is called defrost problem.-------------

So first thing you try is , perform, manual defrost reset procedure.---------

The manual defrost reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. Then check,if same frost is getting collected, then its defrost problem,. If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

I have a Kenmore bottom freezer model 596.75934401. The refrigerator top has stopped cooling while the bottom freezer is working but showing some accumulation of icing. I have unplugged the regrigerator,...


There are a couple possibilities. You need to make sure the evaporator fan in the freezer is working, it circulates the cool air to the top. More likely your coil in the freezer is iced up due to defrost part failure, either the timer or the heater assembly. The back panel is going to have to come off. If you defrost the coil completely, the unit will work again until it ices up again. You have to have the defrost system diagnosed and the defective part replaced

My ice maker not making enough ice . I have already check the water. thank you


When an icemaker slows production, the problem is not the icemaker at all but the temps in the freezer warming up because of an airflow problem either in the freezer compartment evaporator coils or underneath the unit that being the condenser coils. (Fan not working or lint blockage)
Airflow problems in the freezer compartment are caused by the fan or the automatic defrost system not functioning properly so yu end up with an ice block / lots of frost in the freezer compartment on the back wall of the compartment.

Check for ice or large amounts of frost in the freezer compartment. If you note ice / excessive frost, unplug the unit, empty the freezer compartment and do a manual defrost by directing an external fan into the compartment for just over 2 hours. This will ensure the evaporator coils and the freezer compartment drain have thawed. While the manual defrost is in progress remove the rear fiberboard cover from the compressor access and check / clean the condensor coils and fan area.
After 2 hours clean up the excess water.. reassemble the rear cover and return the unit to NORMAL service. It should start making lots of ice in 4 to 6 hours. Here is the kicker... if there is an auomatic defrosting problem your icemaker will after 2 - 3 days again slow ice producion and ice will build up in the evaporator area. You will have to keep repeating the manual defrosting process every 3 to 4 days until the automatic defrost system is repaired.

There are 3 main components of the Automatic defrost system:
1. Defrost control
2. Defrost heater
3. Defrost thermostat or depending on type thermistor

Most of the time the problem is either the defrost control or the heater that fails and the unit stops defrosting.

Refrigerator isn't cold enough, but the freezer is fine. Model number is PSS26MSWASS, Serial number is GM439772, I turned up the temp for the Refrigerator, but its not that cold.


This problem is related to defrost.The defrost cycle is not running as it should be. The other possibility can be ice blockage in the ventilations.The defrost is not working,.The evaporator coil in the inner section of freezer is got blocked by ice .
Try manual defrost reset procedure: ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. If the same problem occurs then it's defrost problem. The defrost board and the defrost thermostat/heater is not functioning properly and it has to be checked and replaced.
-------------------------------------------------
Check the damper if there is too much water collected in the damper then press the damper and remove the water collected in it. The procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the refrigerator section and the refrigerator section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located. Now this problem which you mentioned. In this problem the freezer works but no cooling in fridge, this happens if the thermostat is not functioning or the heater is not heating. Then the ice starts getting collected on the evaporator coil. The evaporator coil is at the internal section of freezer. If too much ice gets
collected then this ice blocks the fan in the freezer section from functioning and this blocks the damper section with ice getting collected there. This all procedure is controlled by the main defrost board of the unit. Now if the damper is not got blocked with too much water or if the ice is not got collected on the damper area then check the evaporator coils. If there is too much ice got collected on the coils, then takes a hair dryer and melt the collected ice. Then see if the problem returns again. But if there is little bit ice collected on the coils and fan is running properly then it's not a problem. In that case main defrost board is faulty and it has to be replaced. The main defrost board is working but its not controlling the functions as required so the freezer works but fridge section not getting cold..

Bottom frezzer is working but fridge is not blowing cold air


Refrigerator gets cold air from freezer compartment. Either the air flow is blocked by food items or ice, or the recirculating fan is not working.

The most common failure is that the freezer coils get all iced up becuase the defroster timer, defroster thermostat, or heater has stopped working.

When it's running, you should feel cold air blowing out of the vents that are in the fridge, otherwise, the 'air tower' (air vent) is blocked with ice.

If you manually defrost the whole thing, and it runs fine for a day or so, then it's not defrosting properly. If you manually turn the defroster timer, and you don't hear the scorching/hissing/gurgling of the defroster working, then that would confirm a fault in the defroster circuits.

Based on the following thread, it's probably a bad defrost thermostat.

Freezer works great, but refrigeration section stopped working


Check the door seals on fridge and freezer to make sure there are NO leaks.
Try manually adjusting air flap that controls air from freezer to fridge, the flap may be frozen or the actuator that controls the flap may be faulty.

If it happens again, check the defrost timer. If it does not self defrost, the cooling coils (evaporator) get plugged with ice and although it is frozen, the ice stops the transfer of heat. Unplugging the unit allowed it to defrost so air could circulate again.

Magtag french door with water and ice despenser door with auto defrost keeps freezing up.


You have a defrost system problem related to the timing device, heaters, or defrost thermostat. Coils for the freezer are inside the back wall and defrosting the surface does not get ice out of coils.
it will not get any better until you have it serviced. This is not normally a project for a do-it your selfer.
