Question about Refrigerators

1 Answer

Ice-O-Matic ice maker won't produce ice. Everything is operating. Compressor comes on but gets hot. I have cleaned the evaporator coil because it looked like it was wearing a wool sweater, but the pressures are very near the same. Low side is 150 and high side is 200 and the refrigerant is R404A. (pressures are approximate)

    The water is flowing free over the face so I believe that the water valves are working fine. This is a commercial icemaker with a large hopper under it. It is not an icemaker in a refrigerator. Did I send my question to the wrong person? If so I apologize and can you direct me to the proper person?

    The room is well above 55 degrees, the unit is located in a kitchen and believe me, they use the kitchen! Everything is operating on the unit, but the surface of the cubing area does not get cold. It is not even cool. The compressor runs, the fan is running and the water is flowing through and into the catch tray. I cleaned the evap coil and checked everything electrically, but still no ice. Could the compressor valves be damaged? The pressures are very close together, 150 low and 200 high. The refrigerant is R404A so does the minor difference in pressures mean that compressor valves are not operating properly?

Hi

If your ice maker has stopped producing ice completely, check these, in this order:

  • It may be turned off. Look for the wire along the right side of the ice maker that looks a bit like a coat hanger. If the wire is in the raised position, the ice maker is turned off. If so, try one of these:
    1. If your ice maker has a small red plastic lever, lower it to lower the wire.
    2. If there's no plastic lever, simply lower the wire.
In either case, the ice maker should begin producing ice again. Also make sure that the temperature is 8 degrees Fahrenheit or lower. If the freezer is too warm, the ice maker won't cycle properly.
  • The ice maker fill tube may be blocked with ice. If so, melt the blockage using a hair dryer-but be careful to not melt any plastic parts! Also check the water shut-off valve or water-inlet valve and replace if necessary.
  • The ice maker head assembly may have broken parts. Look to see if the gears are broken. Check to see if the small plastic arms that rest against the ice rack are broken. Check if the ice maker head assembly is modular and look for any broken parts.

    Hi



    I am sorry i didn't read the last line of your post. The Room temperature must be above 55°F (13°C). Otherwise, thermostat may sense cold room temperature and shut off even though its not full of ice. Also, unit may not restart once it does shut off. Also check if the fan is working and please check for any frost build up on the coils.



    Please do accept this solution and revert for further assistance.

    Thanks

    If the compressor is very hot then its doing its work however, there is a leak in the coils from where the freon is leaking and that is why diffrence in pressure is present. And you cannot check for the leaks in the coils as it needs a freon checking kit and a license to repair compressor related issues. You'll need a licensed tech to do that for you.

Have a scottsmanicemachine doesnt drop ice compressor on water on water runs on coils goes to harvest but makes no ice coil usualy have a ice buildup before it harves


The water runs over the evaporator coil(plate) until the ice gets thick enough, than when the ices touches a switch for the thickness you have it set for, it to go into harvest and the hot gas from the liquid line goes through the evaporator making the ice fall. If you are not making ice, it is the refrigeration system not working, so check the refrigerant, compressor etc like you would on any refrigerator or freezer

Ice machince is going max freeze cycle shut down


1. Possible cause. Water leak. Check purge valve, water curtain, sump, sump hose.
2. Air filters clogged. Clean air filters.
3. Dirty condenser. Clean condenser.
4. Restricted location, intake air to hot. Have machine moved.
5. Ice thickness sensor dirty or disconnected. Check ice thickness sensor probe.
6. Water distributor dirty. Remove and clean water distributor.
7. Inlet water valve leaks through during freeze cycle. Check water inlet valve.
8. Connected to hot water. Check for bleed through from missing check valve in building water supply.
9. Incomplete harvest. Check harvest system.
10.High pressure cut out opened. Check fan motor pressure control, check fan motor, check controller using test mode.
11. Fan motor pressure control open. Check fan pressure control.
12. Fan motor not turning. Check fan motor, check fan blade,check controller using test mode.
13.Water pump not pumping. Check pump motor,check controller using test mode.
14. Pump hose disconnected. Check hose.
15. Compressor not operating. check compressor contactor, check controller using test mode.
Check compressor start components, check PTCR resistance and temperature, check compressor voltage, check compressor windings.
16. Low refrigerant charge. Add some refrigerant and restart unit. If cycle time imporves, look for a leak.
17. Hot gas valve leaks through during freeze. Check hot gas valve for hot outlet during freeze.
18. Thermostatic expansion valve bulb loose. Check bulb.
19. Thermostatic expansion valve producing very low or high superheat. Check evaporator superheat, Change TXV if incorrect.
20. Compressor inefficent. Check compressor amp draw, if low and all else is correcy, change compressor.

Fridgidaire ffht1817lw8 noisy operation


Good Afternoon John, thank you for your post! Your new high-efficiency refrigerator may make unfamiliar sounds. These are all normal sounds and soon will become a common hum in your home. This noise also indicates your refrigerator is operating as designed. Hard surfaces, such as vinyl or wood floors, walls, and kitchen cabinets may make sounds more noticeable.


Listed below are descriptions of some of the most common sounds you may hear, and what is causing them:


A. Evaporator: The flow of refrigerant through the evaporator may create a boiling or gurgling sound.


B. Evaporator Fan: You may hear air being forced through the refrigerator by the evaporator fan.


C. Defrost Heater: During defrost cycles, water dripping onto the defrost heater may cause a hissing or sizzling sound. After defrosting, a popping sound may occur.


D. Automatic Ice Maker: If your refrigerator is equipped with an automatic ice maker, you will hear ice cubes falling into the ice bin.


E. Cold Control & Defrost Timer or Automatic Defrost Control: These parts can produce a snapping or clicking sound when turning the refrigerator on and off. The timer also produces sounds similar to an electric clock.


F. Condenser Fan: If condenser coils are located underneath your refrigerator you have a condenser fan. You may hear air being forced through the condenser by the condenser fan.


G. Compressor: Modern, high-efficiency compressors operate much faster than older models. The compressor may have a high-pitched hum or pulsating sound.


H. Water Valve: If your refrigerator is equipped with an automatic ice maker, you will hear a buzzing sound as the water valve opens to fill the ice maker during each cycle.


I. Drain Pan (Non-removable): You may hear water running into the drain pan during the defrost cycle. The drain pan will be located on top of the compressor for air-cooled condensers (black coils on back of refrigerator).


I do hope this information proves to be helpful. Should you need any further assistance please feel free to respond.

Making ice but won't drop it, then the compressor stops working.It is a Ice-o-machine


You can try and adjust your thickness a bit thicker. If this does not help, your hot gas bypass is not working and the evaporator is not warming. You will need a technician.

My iceomatic ice machine is not producing ice. There is ice frozen to the grate and water is not running


Could be a bad water solenoid. Could also be because it needs to be cleaned. If there is ice stuck to the evaporator, the hot gas bypass is not working. Try cleaning the unit first.

I have an old iceu150ha sku # wb3765001 that is not freezing and or making ice cubes, the compressor is good, the pump is good and the fan works great. the water just keeps comming down like a waterfall...


If the evaporator is not getting cold, it could be lack of charge or the coil is dirty and not allowing the compressor to properly cool. Try cleaning the coil first.

Ice maker is working, but there is water in the bottom of bin


You will need to pull out what ice you have in the bin to get to the drain. Once you have done that, take a hose and force water thru the drain. You may have to snake the drain if is more than a build-up of ice. Once the drain is working, clean out the bin with ice machine cleaner and sanitizer. Restart the machine and make sure no water is dripping from the evaporator above. If there is, it needs to be cleaned.

2000 Amana BX21Vl fridge: ice maker and freezer not working.


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 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. defrost solutions: unplug the fridge. remove the wall of the freezer that is frosted/icing up. use a hair dryer to melt the ice. do not get too close. you will see a drain under the evaporator coil. make sure it is not blocked. the water should run freely to a condensate pan under the fridge that evaporates the condensation with the hot line from the compressor. once the coil is free of ice, frost, and water, replace the panel and repair any of the problems that caused the icing up. plug the fridge in and turn it on. If it frosts up within a week, there is still an issue that not been taken care of. after the freezer freezes again, your ice maker will work again.
