How do I access the frig back to defrost

Clean your coils underneath your fridge and make sure the fan is blowing underneath. Make sure you replace the access panel on back after you are done. Then check your defrost thermostat in the freezer behind the access panel and the defrost heater. If your coils are frozen that would be your problem. When you finish that make sure you set your fridge and freezer back to the factory settings. Rate me if I helped you. Thank you and good luck!

If the freezer is staying cold it sounds like a defrost system problem. A bad timer, heater or thermostat can cause frost to build up on the coils and block air flow to the refrig side. Check out ACMEHowTo.com for troubleshooting the defroster problem.
There is a small duct between the freezer and refrigerator side if this is blocked the frig side won't cool.

I would suggest fixing it . You only have 2 parts in the defrost system . A timer , and the defrost heater which comes with the bimetal , pt . # WR51X10031 .Most probable , is the defrost heater . You will need to remove the rear inside freezer panel , and defrost the coils with a hair dryer . After defrosting , 2 screws hold each ( 2 ) heater on , ant the defrost thermostat , just clips onto the top of the coils .

When this happens, usually the frig side is also not so cold. If frig shows 50 degrees or higher, you have a defrost control parts failure. Can be defrost heater, defrost thermostat, defrost timer, or the air circulating fan in back of freez compartment. If you are not very capable of removing sections of the inner freezer and do not have good diagnostic skills, best to leave it to a professional. Good luck, Macgivor

also check defrost timer,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 In most newer models the timer has been replaced by an electronic control board.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.

Something has failed in the defrost circuit-

Defrost thermostat
Defrost heater
Defrost timer

Reply back if you know how to diagnose electrical circuits, and I'll help you further.

I don't know this particular frig, but evidently the defroster doesn't work. Frost buildup has blocked the flow of cold air.

There is a defrost timer, under the frig, accessible from the front. You can turn it with a screw driver. Turn it till you hear a click. If the timer hasn't been turning, that should turn on the defroster, a heating element nested among the freezer coils. Wait half an hour and if it is defrosting, water should be dripping into the drip pan underneath the frig. If so, then replace the defrost timer and you're good to go.

If that doesn't make it defrost, then the problem is probably the defrost thermostat, in with the freezer coils. When the frig defrosts, the defrost heater stays on until the defrost thermostat gets warm. It should be open circuit while warm. But if it is open circuit while cold, it is bad and is the cause of your defrost problem.

If you open up the freezer coils, use a hair dryer to defrost. That is safer than hot water.

Hope you can fix it.

Check if there is frost on the back wall of the freezer, if so it is not defrosting. Many GE fridges need a new defrost heater every couple of years. If it's not defrosting, you can get by for a while by unplugging the fridge and leaving the freezer door open for 24 hrs, then plugging back in.

Switch off frig and let it completely defrost.

yes, it is defrosting problem.
