Frigidaire frs26znhd1 freezer seems to be icing up and refrigerator is warm

Condenser fan at compressor working?

Contact a professional. Sounds like either your damper door is not operating correctly and not letting enough cool air from the freezer enter, or there is an air leak that is making ice form .

Generally the thermostat that turns on and off the compressor is in the freezer and so is the coils. The control knob that is in the refrigerator section is just to adjust the air flow between the two sections. If the air flow is blocked you don't get cooling in the refrigerator section. This could be a bad fan motor not creating circulation, ice blockage because the defrost cycle is not melting away ice accumulation. If it's defrost problems it could be timer, defrost thermostat, or heater element.

to warm or maybe staying in deforest to long if you don't have a good amount food in the freezer it will warm up in deforest and make ice to lump

Your freezer coil needs a good defrost. You are getting only a little bit of the ice off. It stops cooling because the ice acts like a insulator over the coil so it is unable to cool. Was to get this done is to empty it out and shut if off and leave the door open or maybe a hair dryer or even so warm water.
I hope this helps.

Hi,

All of your cooling coils on this model are located in the freezer. If you are cold enough in the freezer your problem is air flow to the fresh food section.

- There is fan behind the back wall of the freezer, be sure that is running.

- Look for frost build up on the back wall of the freezer, if present we have a defrost problem

- look for the duct or channels between the floor and freezer and top of the refrigerator they could be blocked with ice, if so we have a drain problem.

Let me know what you find and I will help you from there.

Check for two things. Look under the refrigerator and make sure the compressor fan is turning.

Second, check inside the freezer for proper operation of the fan that moves cool air throughout the freezer and refrigerator. If this fan is working, you can probably hear it. It should be behind an access plate in the freezer (near the top). Remove the plate and look at the fan. If it's not turning, you will have to replace the fan motor.

check to see if if the back wall of the freezer is full of ice if so this is an automatic defrost problem
timer ,heater or limit switch

Seems to me that your defrosting timer is not working.When defrosting is not working unit will collect ice on element(Hidden)Could also be fan inside refrigerator which is not working properly.You need a repairman.Jan

Make sure your fan is working ,its in the freezer behind panel .If not the fan your passage area is probably covered with ice and the air cant get in freezer
