Sears Trio model 795.75546400 error message: -88 * 88

I have a Trio model 795.46400 that just started displaying the following on the lcd display:

Filter Reset lit -- Freezer temp reads -88 -- Express Freeze symbol is lit -- Frig temp reads 88 and Lock is lit

Food in the frig is freezing and the lower sides of the unit feel warmer than they have in the past. The panel is locked and will not unlock. Water no longer dispenses which may possibly be from being frozen as well.

I called Sears who can't get here for 9 days! After reading hundreds of horror stories on various internet sites about recalls, motor fires, spoiled food, flooded floors, etc., I was hoping the customer service rep could at least look up the error code to make sure it's not something serious. I usually don't take out the extended service on things, but am sure glad I did non this frig. I love its features and convenience, but this will be probably the 4th time it's beig serviced. Additionally, I sent Sears tech support an email. Given Sears history of poor and slow service, I'm hoping someone out there might know what this means.

    Control panel shows the following from left to right:

    -Filter reset: Red light is lit (though not due for replacement yet)
    -Freezer temp reads: -88
    -Express Freeze: Swirl symbol is lit
    -Frig temp reads: 88 (though temp is now FREEZING everything
    -Lock: Red light is lit (press&hold does not unlock panel)

    Getting cool enough isn't the problem with the frig. It's that it is getting TOO COLD and freezing everything, and the panel is locked so unable to change settings.

  • clfischer565 Aug 05, 2008

    Thanks. I'll try a couple ideas and see if it works. Wish me luck!

Hi,

An alternative supposition:
the 88 is not an error code; to my thinking, it is all the segments of the display 8 lighted up as 6 could be displayed with the top right segment dimmed or a 9 with the bottom left segment dimmed.

This is indicative of a logic/driver problem and therefore would be the main controller board which could likewise explain all other indicators are lit.

The fastest/easiest user action possible is to reset and unplug from the mains in the hope that it is just a system's glitch. Trying again after a few hours. Should this be not corrective, the only option left would be to wait for the authorized service personnel or perform a DIY (do-it-yourself).

Hope this be of additional help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

    Allow me to repost the 88 display interpretation.....
    "the 8 8
    is not an error code; to my thinking, it is all the segments of the display 8 lighted up as 6 could be displayed with the top right segment dimmed in the same manner that a 9 with the bottom left segment dimmed."

As to the 88 display, there is one thing to try but it is a longshot:

Try to press the Energy Saver and Freezer temp buttons at the same time for 5 seconds, see what happens.

The 88 is not a used error code.

If that does not work then, I believe that Sears will be replacing your main board (motherboard)for this unit, as it sounds like it is bad.

Sorry for your trouble!

    If you have old wiring, frequent power supply issues (spikes, strikes, etc); these issues may be contributing to these issues!



    If you have other appliances that have frequent problems, you may want to invest in "whole house surge protection" or "Meter Surge Suppression".



    Or you just may have the unlucky refigerator!



    Good luck either way!

A refrigerator or freezer that doesn't cool well enough may have a problem with its evaporator coils, condenser, or condenser fan motor. Frost build-up on evaporator coils, or condenser coils that are covered with dirt, dust, or lint can reduce how well a refrigerator can cool. If you notice ice getting thicker on the inside walls, inside bottom, or inside ceiling of the freezer, you have what is called a frost build-up. The problem is either with warm, moist air getting in through an old inefficient door gasket or the defrost system.
Self-defrosting refrigerators have coils and a cooling fan that need to be cleaned regularly. If the coils get coated with any contaminants, they may not cool the refrigerator properly. The coils are usually thin and black and they go through fins that dissipate heat, just like a car's radiator. They are located behind the lower kick-panel or on the back of the refrigerator. To clean them, turn the power off and use this condenser coil cleaning brush, or this condenser coil cleaning brush , and your vacuum cleaner. Even if your coils are below the refrigerator, you won't be able to get to all the condenser coils from the front, so it's a good idea to pull the refrigerator out and clean the coils from the front and the rear of the refrigerator. Give the fan a dusting as well. Sometimes other things can be the reason behind poor cooling, like the condenser fan motor. Anytime the freezer fan is running, the condenser fan should also be running.
A frost build-up inside the refrigerator usually means that there is a problem in the self-defrost system. You may even have damaged door gaskets. When you open the refrigerator door, you also let in a blast of warm, often humid air. This moisture usually freezes onto the evaporator coils immediately. Self-defrost refrigerators are supposed to self-defrost between two and four times out of every 24 hour time-frame. They basically turn off for a few minutes several times a day. A defrost heater kicks on to melt any frost build-up on these coils, which allows the frost and ice to melt, then it drains off to the pan underneath most refrigerators. Unfortunately, when a defrost component fails, too much frost builds up on the evaporator coils. When this happens, the circulating fan can't draw air over these coils. With no air flow over the evaporator coils, the refrigerator compartment will lose its cool.
To determine if the self defrost system is faulty, it's best to remove all the food from the refrigerator and freezer, turn your thermostat to the Off setting, and just leave the doors open for 24 to 48 hours, and let the refrigerator defrost. Keep an eye out for an overflow of water from the drip pan on the bottom of the refrigerator.
After everything has completely melted away, set the thermostat back to a regular setting. If your refrigerator starts operating properly, the symptoms lead to there being a problem with one of three other components in the self-defrosting system, the defrost heater, the defrost timer, or the defrost thermostat.
If, after testing these components, the refrigerator still doesn't get your foods cool, there may be a problem with the refrigerant level and you will need to contact a professional appliance repair person.

Refrigerator warm, display blank but freezer still works


The Er DH error code indicates the temperature sensor on the evaporator coil did not reach 50 degrees within one hour.
This would indicate the control board did put the refrigerator through a defrost cycle.

This problem could be caused by a defective relay on the control board, a defective defrost heater, a broken wire to the heater, or a stopped up drain on the defrost pan causing ice to form on the evaporator coil.

Before replacing the control board, someone should remove the food from the freezer, remove the freezer drawer, and remove the evaporator cover to expose the evaporator coil, heater, and defrost sensor.
The voltage to the defrost heater should be 120 volts ac.
The defrost heater is part of the evaporator coil and is not replaceable as a separate part.

You can test the operation of the defrost system by pressing "Ultra Ice" and "colder freezer temp" for 3 seconds.
The first time you press and hold the buttons the board will test the compressor, fan, and open the damper.

All displays should be on.


The second time you press and hold the buttons the board will test the compressor, fan, and close the damper.

The third time you press and hold the buttons, the board will turn the compressor and fan off and turn the defrost heater on for around 25 minutes. This would let you know if the defrost system is working.

Kenmore Elite Trio Fridge - Getting ER F5 error on display


Er-FS error code: Failure of freezer sensor.
I have been finding the fuseable link in the defrost system on these models open preventing the defrost cycle.
This would involve removing the freezer back panel and removing the sensor and fuse from the evaporator.
It's just a plug in.

Help....kenmore trio refrigerator, error message "er co"


The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.

This is an error code that pertains to the evaporator motor but could also be the main board.
If the evaporator motor is running, the main board will probably need to be replaced.
It could be a wiring problem but it's not very likely.

If the motor is not running, some voltage checks will need to be made, at the motor and board, to determine which component has failed.
These checks require a meter and can be difficult to make, even for a technician.

Kenmore 795.7731 Fridge warm;freezer cold - Error er dH


I faced the same problem for Kenmore elite Trio Model # 795.77543600 bottom freezer refrigerator. The issue as pointed out by Medeer on fixya.com, turned out to be the part called component assembly, part number 6615JB2005H. I got this replaced yesterday but for 4 hours I did not notice any cooling... so I thought it did not work.... but then in the morning I notice that the issue has been resolved, the refrigerator is cold and there is no eR dH error message. Thanks to all who shared on this site.

Hi. Error FF is your Fresh Food Fan. Otherwords, the evaporator fan motor has failed. You should replace the motor and motherboard. You may get by just replacing the motor. Sears doesn't manufacture the refrigerator. They just pay extra to have Kenmore put on it. Its the manufacturer that needs to back their equipment. If you bought it from Lowes, you can't hold Lowes responsible for the ongoing issue. They sell the same refrigerator. Anytime this model refrigerator displays an Error code, unplug it for 5 miniutes and replug it. Sometimes it was a computer misfuction. Good luck! Mack
