GE refrigerator gsh22sgress Freezer is cold but fridge is not

It's that simple. Freezer is cold but fridge is not. Adjusting temp doesn't seem to matter. The flap between the two is open but air not circulating into fridge.

How do you fix this problem?

Where is thermostor located?

Jazz board. https://www.amazon.ca/Whirlpool-W1050327...

It is easy to do and fixed my problem.

It is a common problem that my repairman wanted $500 for until I came across this solution. I had the same problem of the freezer still ice cold but the upper fridge was warm due to massive frost building up on the defrost fins in the freezer.

The auto defrost cycle wasn't kicking on.

how did you fix it? Where is the auto defrost?

We are dealing with this right now too. Would love to know answers.

The Evaporator Coils are Frosted Over

If the freezer is cold but the refrigerator is warm and the evaporator coils are frosted over, there may be a defrost system problem. Several times a day the defrost heater assembly turns on for a few minutes to melt away any frost or ice that may have accumulated on the evaporator coils. If the defrost heater assembly has burned out, or the defrost thermostat or defrost control have failed the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling. The most common cause for this condition is a problem with the defrost system.

Evaporator Fan Motor

If the refrigerator freezer is cold but the refrigerator is warm, the evaporator fan motor might have failed. Every refrigerator has a set of coils called an evaporator. These are the coils that get cold. A small fan and motor is mounted near the coils. This fan and motor - called the evaporator fan and motor, draws air over the evaporator coils and circulates it throughout the freezer and refrigerator. If the fan fails, the freezer or refrigerator will get much warmer than usual.

Damper Control Assembly

If the freezer is cold but refrigerator is warm the air damper control might be stuck closed or broken. The air damper control is either an automatic or manually operated door which opens and closes to let more or less cold air into the refrigerator compartment. If it doesn't open properly it won't let enough cold air into the refrigerator. If the evaporator fan is running, the damper door is open and no air is coming out. The evaporator may be frosted up caused by a defrost problem.

Thermistor

If the freezer is cold but the refrigerator is warm the thermistor might be defective. The thermistor is a sensor which monitors the air temperature. It is connected to the control board. If the thermistor is defective the refrigerator does not cool or may cool continuously.

Temperature Control Board

If the refrigerator's freezer is cold but the refrigerator is warm the temperature control board might be defective. The temperature control board provides the voltage to the fan motors and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.

Defrost Thermostat

If the refrigerator freezer is cold but the refrigerator is warm, the defrost thermostat might be defective. Several times a day the defrost heater turns on for a few minutes to melt away any frost that may have accumulated on the evaporator coils. In order for this to work, the defrost thermostat has to sense that the coils are cold enough. If the coils are cold enough the defrost heater will turn on. If the thermostat is defective it may not be able to sense the temperature of the coils and then won't turn on the defrost heater. If the defrost heater doesn't turn on, the frost will build up on the coils and eventually no air will be able to travel through the coils to provide cooling to the freezer or refrigerator. The defrost thermostat can be checked for continuity. It should have continuity when it reaches the low temperature of its operating range.

Main Control Board

If the refrigerator's freezer is cold but the refrigerator is warm the main control board might be defective. This is not common. The cause of this problem is almost always in the defrost components.

The main control board was just replaced. The damper control assembly opens on its own and is open wide which tells me the fridge is trying to cool. The freezer stays cold. There is no air coming out of the damper door so I'm guessing there is a fan that is stuck or not working. How can I check the defrost thermostat, temperature control board or see if the coils are frosted over. if the coils were frosted over would the freezer still be cold? thank you.

Had the same issue with Freezer cold but refrigerator was warm (64F) check the damper door which was open. My model is a built in fridge with a bottom freezer drawer in the process of removing the covers to get to the evaporator coils and fan they fan suddenly turned on. I know it was not on until I started to remove the cover, so I am not sure if it was frozen or a piece had ice had stopped the fan blades but i could now feel cold air coming into the refrigerator compartment. Coils also seemed fine and not frozen over.

so if we've replaced the thermistor, checked for continuity... still fridge isn't quite cold enough...air coming in from damper, but not cold enough and frost in freezer.... would your next step be to replace the defrost heater?

por

The main jazz board was the culprit on my Maytag. It took two years and many frost melting sessions to figure it out but it was the main board. A relatively undifficult repair.

por

My freezeer is extremely cold (-32 Celsius) and the rerigerator not cooling. The fan is working. What would be my next step?

Have tried thawing - didn’t help.

I had a very similar problem. The defrost system wasn’t working properly and the evaporator coils were frosted over and air was not circulating into the fridge well. After defrosting, the fridge returned to normal working order. For a while. A few months later, the problem came back. In my case, a clue was that the hole that drains the defrosted water was plugged with ice. I was slow to figure out that there was a clog of gunk in the drain line (not sure where it came from) because it never occurred to me that was possible. It seems to be working better now after defrosting AND cleaning out the blockage in the drain line.

Turned out to be the evaporator fan.. still stops some times but just tapping the cover that houses the evaporator coils and and fan seems to get it going again. Not sure if the fan is failing or if it's freezing over and getting jammed I ordered an extra motor just in case but I haven't replaced it until I absolutely need to.

Where is the evaporator fan located?

In the freezer compartment right next to the evaporator coil.

Hi @fixitnow414 ,

The fan located in the underside/rear of the unit is the condenser fan.

The evap fan is IN the freezer compartment behind a panel.

Here’s a link to the relevant section showing the parts. The evap fan is part #5

The evap fan stops if a door is opened and starts when the doors are shut. It will run as long as the compressor is running.

You may have to place an ear against the fridge to hear if it stops when you open a door and starts again when you close the door.

If you can’t hear it it may be faulty or iced up. If it is iced up it could be the defrost heater is faulty.

Had same problem on my Kenmore. Was the fan in the freezer compartment that forces cold air up to th fridge. Had somehow become cocked and hit something that stopped it dead. Just straightening it solved the problem. Motor did not burn up so don't need a new one. This problem is not mentioned in your fixes.

I'm having the same issues with my refrigerator has been a while now every 4-5 months the refrigerator part starts getting warm I believe the defrost heater isn't working as it should ice builds up and stops the fan from circulating air I have to disconnect for a couple of days and let it thaw and then reconnect and then works just fine can anybody tell me where the defrost heater is located or how to change it out

por

I had a defrost heater replaced and the defrost thermometer replaced and it worked fine for a few days but now it's doing the same thing! So what could be the problem now!?

Hi @marshagail,

Assuming that you have a Maytag Mff2558vew2, see my answer (5 above this one) how to check if the evaporator fan is working or not without having to take the cover panel off in the freezer compartment to actually see if it is working or not.

Although if you can’t hear if the evaporator fan is running then the panel will have to come off anyway so that you can see what is happening and if you have to replace nay parts.

Here’s a link to the parts to show where things are.

Hi,

What is the model number of the fridge?

There may be a problem with the damper unit not allowing cold air from the evaporator fan to enter the fridge.

Don't know your fridge but some side by side fridges have two evaporator units with fans, one in the freezer and one in the fridge.

Search online for "(insert make and model number of fridge) parts" to find suppliers that may have exploded parts diagrams which will show you how the fridge is set up i.e. 1 evaporator unit with fan in the freezer and damper unit to fridge or perhaps 2 evap units with fans, one for each compartment, freezer and fridge.

If it is a 2 evap unit setup then there may be a problem with the fan in the fridge or perhaps the temp sensors etc.

It could also be a problem with the fridge temp sensors in the fridge on a 1 evap unit system telling the control board that it is cold enough when it isn't. etc.

One more think to look at. I was having the same problem. Freezer was cold but refrigerator was actually hot. On mine it ended up being a stuck door light switch. My GE built in uses four 60W bulbs. They were staying on all the time. The heat generated from 240W of lightbulbs just overwhelmed the ability of the fridge to keep cold. I unscrewed the light bulbs and the fridge started cooling down again. I have a new switch on order.

@mayer Answering your “diagnostics”, the freezer is cold like a refrigerator should be, not like a freezer (doesn’t freeze anything). So no idea if by “cold” you mean it freezes or it means something else.

“The Evaporator Coils are Frosted Over“ Nope, they’re not.

“Evaporator Fan Motor“ Nope, it runs fine.

“Damper Control Assembly” Again, there’s nothing frosted, no ice at all.

“Thermistor” Haven’t tested that part, should try doing it when I find out its location.

“Temperature Control Board“ Haven’t tested that one either.

“Defrost Thermostat” Again, no ice so that’s not the problem.

“Main Control Board” There’s always a first time for everything so who knows.

My freezer is cold but fridge is not cold so I switched it off 24 hours and cleaned ice inside and start again so it was working perfect for a few days. Then ice builds up in the freezer and the fridge is not cold but freezer ok.

I have a Maytag Mff2558vew2

Double door upper fridge with lower freezer drawer.

My freezer is cooling just right, my refrigerator is not cool at all. I feel like my evaporator coils are frosted over because there is 0 air flow coming into my fridge, but the damper control assembly is doing its job. Here is where I get confused, could it be evaporator fan motor, thermistor, temperature control board, or defrost thermostat ?

If the evaporator fan is located in the underside/rear of the unit, this fan is working properly. This fan is controlled and given the signal to turn on and off if I'm not mistaken right? So what could it be or how can I move forward with my fix.

Hey! Yikes! My fridge and freezer are no longer keeping items Frozen or cold like it should. It also recently started making a low buzzing like sound and has frosted over a lot on the back panel. I'm on a fixed income can you please tell me if it's salvageable? Thank you for any help you can offer.
