what the problem most likely is a failed part of the defrost system Do you see a bunch of frost built up on the back wall of the freezer? If you do frost build up, take off the back wall of the freezer and replace the defrost heater and defrost thermostat. A hair dryer could be used to melt the built up frost from the coil behind the back wall. Another part that will cause frost build up is the defrost control, that isn't the freezer behind the back wall but instead it is part of the main computer board on the back of the refrig. I would replace heater/defrost thermostat first though, since they are the most likely to fail parts.
I hope my answer will help you to fix your refrigerator, Gene
I think you meant you have a GSL25JFPHBS (not 85).
It sounds like you have a defrost problem. If your refrig. was off for some time, like a day or more, or it was manually defrosted, it would work for about 2 weeks before the problem would re-occuer. This is caused by a build up of frost on the cooling coils, preventing air flow over them. Un-load the freezer and remove shelves and the back wall inside the freezer. Melt the frost with a hair blower, and replace the defrost heater (part # WR51X10055) and for good measure, replace the defrost thermistor (part # WR55X10025) located at the top of the cooling coils.
Open freezer door and look for any frost on the back wall inside the freezer. That would indicate a defrost problem.
Disconnect power to refrig. Unload freezer, Remove shelves and back panel inside freezer. Melt frost with a hair blower. Replace defrost heater located at the bottom of the heating coils. (Note: It may look different than the original, but insturctions enclosed with replacement cover that) Might as well replace the evaporator thermister at the same time, as your problem is about 98% of the time one or the other of those parts. The thermister is a white pencil shapped item, about an inch long, located cliped to the top of the cooling coils you just defrosted.
If you don't have the parts on hand, defrosting only will get your refrig working again for several days, while you obtain the parts.
Note: non-water dispensing is the result of the cold air from the freezer not being able to continue over the frost blocked coils, so it migrates back though the return air vent in the bottom of the refrig, resulting in a frozen water line, and often freezing in the bottom bin of the refrig.
Open door let too much moisture into refrigerator. (The cooling coils, behind the back wall of the freezer compartment, are blocked with frost) If you unplug the refrig for a day or so it will work again, or you can take the back wall out from inside the freezer and melt the frost with a hair blower.
There is a good chance that the evaporator on the refrigerator side is frosted up due to a faulty thermal fuse or sensor or both. Since these units have more than one evaporator, there is no damper to get stuck.
More likely a defrost heater. Look inside the freezer at the back wall. Any frost there? If so, turn off refrig., unload freezer, take back panel off inside freezer, and use a hair dryer to melt off the frost. Replace the defrost heater located at the bottom of the frosted coils. (New heater may appear different than original, but instructions are included) If you don't have the defrost heater on hand, just manually defrosting the coils and re-starting the refrig will get is cooling again for at least a week before problem will re-occur. (this give you enough time to get the replacement part)
What has happened is that the evaporator (the cooling coils inside the freezer) have frosted up due to all the moist air which entered the refrig with the door open. This frost has blocked the normal flow of air within the refrigerator/ freezer. Turn unit off, unload freezer, and leave freezer door open for several hours to allow built up frost to melt. Better yet, remove the panel at the back of the freezer and melt the frost off with a hair blower.
Your evaporator coils frost up in normal use
and every eight hours or so the entire unit shuts down and the defrost heater
comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips
into a drain pan and through a drain tube to the drain tray under the
freezer/refrigerator where it's evaporated by the condenser fan.
If the evaporator coils behind the back panel of the freezer
are icing up because of auto defrost failure that will stop the circulation of
check defrost timer, defrost heater, defrost thermostat. In
most newer models the timer has been replaced by an electronic control board.
If the heater and thermostat are ok it’ll be the control.
You can turn the defrost timer till it clicks
and everything shuts down. The heater should now come on. If it does, replace
the timer. If it doesn't, check the heater and defrost thermostat. Turn the
timer again till everything starts back up to end the defrost cycle.
Remove back wall from inside freezer and melt all frost with a hair blower. The most likely cause of the frost build up is a burnt out defost heater, second most likely cause is the defrost control. Can't give you part numbers because you don't list a model number or even a brand. Melting the frost and not fixing the underlying problem will get your refrig working for a week or so until the frost builds up again.
Sounds like a defrost problem. Check to see if
there is any frost buildup in the back wall of the freezer. If so, it is not
defrosting as it should.
bad defrost timer/control board
bad defrost heater (in freezer)
bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice
melt in the freezer overnight with the door open. Then try it the next day, if
is cooling fine then you need to have a service person replace one of the above
if you already checked this and think
it is a different problem then let me know, i will help you figure it out.
