Question about Freezers

Open Question

I have a owned a Fisher & Paykel N388 freezer for about 5 years. On several occasions it has stopped blowing cold air (now blowing room temperature air) and the freezer has started to thaw. If you turn the freezer off for a while and then turn it back on it starts blowing cold air again and appears to be working OK. Does any one know what the problem is Fisher & Paykel don't want to know about it.

SOURCE: Food in freezer is thawing, compressor very hot to the touch

It sounds like the motor to the circulating fan is wearing out . This fan is hard to diagnose as it will spin the blade , but as you said it will not spin fast enough to circulate air thru the freezer and refrigerator. The motor is DC non brush type. It will cost a minimum of $300.00 to repair/replace this fan assembly, but it is worth that compared to replacing the refrigerator

SOURCE: Frigidiare upright freezer has just stopped cooling

I was hoping it would be something like a cracked door seal, or a faulty thermostat, etc., but after reading the rest of your info, I've concluded the likely cause is a slow leak in the refridgerant line(s). I've seen many of these fairly new upright freezers with this problem.

Finding the leak is easy for a service tech to find, but the cost of the service tech isn't cheap and unfortunately, the repair cost will probably exceed the cost of a new freezer, but you can try to call a repair tech and see if they can give you a rough estimate over the phone or if they think it's worth fixing, etc.

My advice is to replace it. The cost of food you've lost has probably exceeded the price of a new freezer - and you've had this happen twice now. These days it seems that some appliances are being designed and built as "throw aways" due to the high repair cost.

Wished I had some better news for you, but unless you've got all the specialty tools; (charging gauges, vaccum pump, Freon, etc.) needed to do the repair yourself, along with the technical knowledge, it's likely not worth having the repair service contracted. Best Regards.

SOURCE: Woods freezer has thawed twice in the last year.

HI, you will need to inspect the compressor to make sure it is cycling in intervals. if the compressor is not cycling, this will confirm compressor failure. The evaporator fan blows cold air into the freezer and from there it vents into the refrigerator. Occasionally the vents between the freezer and refrigerator can become clogged with ice, food or other debris. In most refrigerators the cold control for the refrigerator opens and closes these vents. That mechanism may become inoperative resulting in the vents becoming stuck open or closed.

Inspect the vents to determine what is preventing the free flow of air. An overcrowded refrigerator or freezer may be the cause. In other cases the vents may need to be cleaned or ice melted away. To remove a build up of ice, use a hair dryer set to "low". Using a higher setting may damage the freezer. WARNING: Do not let melting ice drip onto the hair dryer. In some models, the vent is located under the temperature control console. The housing either snaps into place or is held in place with screws. Remove the screws, or gently depress the retaining clips with a small screwdriver. Allow the housing to hang by its wiring. A freezer vent control may also have to be removed to access the vent. In some freezer-on-top models, it may be necessary to remove the floor of the freezer to inspect for obstructions.

The condenser coils dissipate heat. If dust and debris accumulate around the coils, your refrigerator may not be able to cool properly, it may run continuously or it may stop completely as a result of an overheated compressor. You should clean rear-mounted coils once a year. Unplug the refrigerator before cleaning. Refrigerators are heavy, never tip one forward or backward. Never attempt to move a refrigerator without an assistant. Vacuum or brush the coils. If coils have a filmy build-up, use warm soapy water to clean them. Take care not to spill or drip water onto the components of the refrigerator.You should clean floor level coils at least twice a year. Unplug the refrigerator before cleaning. Vacuum or brush the coils. Remove the grill from the front of the refrigerator and use a vacuum with a wand attachment to remove any dust and debris. The grill should snap off and on. Pull firmly toward you and possibly upward to remove the grill. If it does not come off with a modest effort, check for screws or retaining clips that may hold it in place.

Another inspection point will be the door seals. This is a easy way for the cold air to escape from your unit as well. this will cause the temperature to rise. The seal should make smooth continuous contact with the refrigerator case. When the seal does not seal completely, warm air enters the appliance. This results in more frequently compressor operation and possibly the inability of the appliance to maintain proper temperature. To test the seal, use the dollar bill test. Place a a dollar bill or a piece of paper between the seal and the refrigerator and close the door. Now pull the paper out. You should feel tension as you pull. Retest along the entire door seal. Replace the seal if the test was unsuccessful.

Next will be the door switch. The interior light in most refrigerators, and the fan in some, are controlled by a door switch. When the door is closed, the switch is depressed and the interior light goes off and the fan resumes normal operation. If the door is misaligned or the switch malfunctions, the refrigerator may become warm as a result of the non-operation of the evaporator fan and the heat generated by the interior light. Test the switch for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should change from a reading of infinity to zero when the probes touch the terminals. With the probes still touching the terminals depress the switch, the reading should change back to infinity. If it does not pass both of these tests, the switch should be replaced.

Be sure to confirm evaporator fan function as well. if the fan is defective, it will prevent proper cooling as well.

This will conclude the most common issue with a under preforming unit. I would advise to check all the above and, if the unit continues to not cool after all the above adjustments are made, i will recommend replacing the cold control device,thermostat and main circuit board.

Concerning the defrost switch:

To test whether the defrost timer is simply failing to advance, locate the advance screw and turn it clockwise until you hear it click. This advances it to the next mode. If it was cooling before, it is now in defrost mode. Simply wait about 35 minutes and check whether it has left defrost mode and has resumed cooling (listen for the compressor). If it does not advance, the timer motor is probably bad and the entire timer needs to be replaced.

The system is either blocked or you have a gas leak but i would expect it is blocked and the only way to find out is to get a refrigeration engineer to check it for you, but explain the problem to him first and make sure he can help before you spend money.

Doesn't stop running but is very cold


the cold control is probably stuck closed. if you have a meter, you could pull the control out to check continuity. if nothing else throw in a thermometer, standard freezer temperature is +5 to -5 degrees F.

Can a fridigidare fc5n chest freezer be recharged


If the unit's Compressor is not starting you need to bypass everything and test the compressor directly to see if it will run. best done buy a qualified Appliance tech unless your from and electrical background? also when the motor/compressor is tested they can see if the freezer starts to freeze down. Because of the cost of changing the Compressor and the fact that a lot of the gas leaks in these units can not be repaired due to the leak being inside the freezer walls a new Freezer is still the best option. Also when a Fridge or freezer is left to sit for 5 years the Compressor is likely to have seized and rust may ave formed inside units copper pipes. Cheers
I'd recommend a new Fisher and Paykel Chest freezer with a extended warranty. cheers

Fisher and paykel vertical freezer N308 model


bec,

Sounds like you are freezing up! The coils are so frost-laden that they will not allow the unit to function. The unit will need a complete defrost. I'm not familiar with the exact layout of this unit but I can tell you that it needs to be shut down, have warm air blown into the fan area and completely freed of ice. If you just leave it open and turned off, this takes about 2 days.

Possible causes: humidity in the air is condensing...very humid area, too much 'window shopping', not closing the door completely, possible damaged door gasket.

Others: (on older units)

Possible defrost timer problem...or low gas. Try the defrost route. We'll go from there.
