My frigidaire is no keeping cold or freezing On the back of the fridge are black coils running top to bottom is that what needs to be cleaned?

The drain in the freezer behind back lower panel
needs opening. You can see it at the bottom of the back panel
underneath the evaporator coils. (The cold coils)
Run Hot water in the drain until it clears or use a hairdryer.
When the defrost melts the water it goes down the drain
If the drain is clogged with Ice or ? The defrost water
overflows into the ref. or freezer or on floor
Run Hot water in the drain until it clears or use a hairdryer.
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

Try taking the back off the fridge and vacuuming off the coils. Give it a good cleaning. If that doesn't work you probably need a new compressor which is usually cost prohibitive.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

Is this a self defrost model? Frost inside the freezer could be an air leak around the door gasket. Remove the back panel in the freezer and completely defrost the coils. Is the fan running in the freezer. That will make the frig not be cool. With the door closed peek in the gasket to make sure the light is shutting off, this will warm a frig also.

Possible defrost timer or thermostat failure.

Hi: Those areas are designed to be warm to keep moisture from forming there(Moulion coil). When they get hot it means the fridge is over working. The condenser coils remove the heat from the fridge. When clogged the heat will leave anywhere it can. The moulion coil is the strip you described,and will overheat when the condenser coils wont disperse the heat. Most likely the coils need a good cleaning, on the bottom of the ref. Use a coil brush and a vacuum. Or even an air compressor to blow the dust and hair out; plan on dusting the house too. Pull the grill off the front and clean them. If real bad pull the panel of the lower back and clean it out too. Since you work in detroit the dust and hair on the coils would be like putting a blanket over your radiator. Parts would heat up. I hope it's just the coils. If a compressor is failing you can get the same symptoms. I hope it is the latter for you, as I'm in your boat also. I hope this helps, Jeff

sounds like the condenser is bad, feel the copper coils they should be cold and the condenser should be hot/

Sounds like you're low on gas...assuming that the condenser coils are clean.

the unit is loosing the freon supply to the evaporator.you either have a leakage,a blockage or the compressor is not pumping to full capacity.
