Re: freeze will not run doors heat nothing else

That is known as a puffed capacitor and usually indicates a power supply problem as well. The cap can be changed with a 50/50% chance to work again unless it took out other components.

The top two shelves are not freezing and the food on those shelves and that area of the door have defrosted. The bottom seems to be freezing. I can hear the fan running and do not feel any drafts from

Obviously that freezer is not achieved the required temperature. There are several reasons for that:
- Defrosting system is not working, which leads to accumulation too much ice on the evaporator that prevents heat transfer and reduces air circulation despite the fan is running.
- The problem with draining condensate after defrosting cycle which also leads to accumulation of ice.
- Leaking gas from the cooling system (reduced cooling capacity)
- Faulty compressor

Why mu refrigerator rrtg21pabb ia working but not freeze

If the refrigerator is not defrosting, the defrost control board might be defective. The defrost control board monitors several conditions and determines how often to run the defrost cycle. If the board fails, the refrigerator will not go into the defrost cycle. Eventually, ice will build up on the evaporator coil and then the refrigerator and or freezer will not stay cold enough. This will depend on where the evaporator is located. It's prudent to check the defrost heater and defrost thermostat for continuity before replacing the defrost control board.

My freezer seems to turn itself off. The number panel is blank and it will run nonstop or the number panel looks funny and it is not running at all. Also it will just turn itself off, light and all. I...

In all likelyhood, the control panel has a bad capacitor. You can check it and replace it yourself if you have a soldering iron. If the control panel looks like this:
You can remove it by unplugging the freezer, then carefully prying the unit off the front of the freezer with a screwdriver. There are several tabs holding it in place, be careful not to break them.

When you get the unit out, turn it over and inspect the capacitors (the three round things attached to the circuit board):


If you look carefully, you will notice that the top and bottom capacitors are flat on the top, and the one in the middle is bulging up. This indicates a blown capacitor. Another view:

If one or more of your capacitors is bulging or leaking, that's your problem.

The circuit board is held in place by four tabs; place a small flat screwdriver in the slots (visible just to the right of the green resistor in the photo above) and use another screwdriver to push back the tab holding the board in place. Once you get it free, go on to release the other 3 tabs. Carefully remove the board.

Once you have the board out, you can use a soldering iron to melt the solder holding the bad capacitor in place and remove it, then you will have to obtain a replacement capacitor (Radio Shack sells them for about $2.) and resolder it back where the bad one was. The ratings for the caps are printed on them, the typical value for the larger one is 1000uf @ 16V, but I would recommend using a 1000uf @ 25V - 35V, as the original is prone to fail. The two smaller ones are typically rated at 220uf @ 50V.

The circuit board is coated with a layer of sealer, so you may have to sand the tiny soldering pads before you can resolder the part back in. Be sure to put the cap back in the proper orientation; the circuit board is marked with a + where the positive (longer) lead should go, and the cap is marked with a - on the negative side.

Put the board back in the plastic holder (make sure it's right side up) and reinstall. Plug the freezer back in and it should work.

NOTE: If the capacitors are not bulging or leaking, they are not your problem and this will not fix the issue.

Stuff on top shelf wont freeze

There must be a leak at the top to allow air in. I am assuming the rest of the freezer is fine. Do you find frost on the ice trays. Check the seals on the doors.

My Fridgidaire upright Gallery freezer is freezing my food but the appliance seems to be constantly running and the temperature control on the outside is reading 29 Celsius when it obviously isn't

Hi Susan Abboud - Modern freezers have increased storage capacity and keep more even temperature that may require the compressors to run longer but use less energy. Was the unit disconnected previously for any reason? If so, freezer requires a minimum of 4 hours to cold down completely. Confirm that the temperature control is not set too cold and that the door is not being open frequently. A dirty, cracked, worn or poorly fitted door gasket can allow warm air to enter the unit causing it to have to run longer to remove the warm air. Leaks in the door seal will cause freezer to run longer in order to maintain desired temperature. Cleaned the gasket, if it is too damage then it will need to be replace. You can check and see if the door seal is bad by, placing a dollar between the gasket and cabinet. Check to see if the door is being blocked by anything stopping it from closing properly. If nothing is stopping the door then replace gasket. Keep in mind that there should also be at least 4-6 in of air space on all sides of the unit. If freezer is built in or has items stored on top that cover the unit, the can cause long run times, high temperature in the freezer and premature failure to the unit. Do not block the toe grille on the lower front of the unit. Sufficient air circulation is essential for the properly operation of your freezer, about 3 inches around the unit.

Our chest freezer isn't keeping food on top frozen although the bottom is still frozen solid?


Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze - store them in a different spot. Doors not closing properly making the fridge run too long is something else to check for.

Hope this help in solving the problem....

The freezer is running, and the light is all coming on but it is not freezing the contents in the freezer?

Hi and welcome to FixYa. I am Kelly
If your sure the compressor is running and it is not freezing then there has to be a system coolant leak.
Having said that there are a few things to check:
1. Is the compressor in fact running Y / N
a. Yes = coolant level problem or coolant system blockage
b. Not running = (Possibilites below)
1) PTC / Klixon Thermal overload failure
2) Run capacitor failure
3) Temp control failure
4) Automatic defrost thermostat or thermistor
5) Defrost timer or Adaptive defrost control failure (depending on model)
2. Is the compressor very hot to the touch or room temp?
a. VERY hot = unplug the unit for at least 30 minutes and then plug it back in.
b. ROOM temp = any of the above in 1b items 1) - 5)
3. Is the evaporator fan running?
a. Yes = Temp control is ok Defrost system is probably ok
b. No = same as 2b

With a model number I could pass on a few additional things to do. For the moment use the above.

Thanks for choosing FixYa,

My hotpoint under counter freezer isn't freezing properly

A freezer has a very simple operating design and there are only 2 customer serviceable components.
1. Make sure the cold control is set at the proper level.
2. Make sure that the door seal is making good contact with the cabinet. You can apply a thin coat of Vaseline to the door seal to help tight closure of the door.
Keep the door opening to a minimum during extreme heat conditions. Any small air leak can drastically reduce the operating norms during extreme heat conditions.
That's about all that you can do to regain control, the rest will have to be performed by a refrigeration tech. if you are still dissatisfied.

Ice is forming at the bottom of the freezer and freezing the bottom draw shut. it doesn't appear to be leaking and the door shuts properly. it's supposed to be a frost free freezer....


High humidity in the immediate area causing condensation to freeze at the door opening

A frozen defrost drain line not allowing water to drain off when the unit is in defrost

A bad door gasket causing an air leak

Some freezers have a heated perimeter to reduce condensation. If the stop working, moisture can accumulate arounf the door perimeter and freeze.

Leaving the door open too long or something obstructing the door
