So she's about 8 1/2 years old now and has been faultless until about a week ago.
The freezer is working fine but the refrigerator part is just cool. I cranked up the temps of both freezer and frig, but it doesn't improve the frig apart.
There seems to be a little square inlet in the rear top corners of the frig ceiling that seem to have frost in them.
There is slight water collecting on the rear of the ceiling center soffit; some sort of duct or something screwed to the ceiling.
Only a small amount of frost can be found on the base of the rear wall of the freezer.
I can't recall hearing the defroster run lately, but I can't really attest that it hasn't when I'm not paying attention.
We have had some serious hot weather in the past few weeks, but we don't abuse the frig by leaving the door open and the seals appear good.
There is just such a difference in temperatures between the freezer and the lower box that I have to suspect a problem.

Measure the freezer temperature and post, might have system problems.

With contols cranked up to 8 of 9:
Freezer is 10 degrees F.
Bottom shelf of Frig is 51 degrees.
Any point in trying to defrost the frig ceiling ducts to buy some time?

Pull the freezer panel and describe the frost pattern, should have light frost on all the coils. Use a hair dryer to defrost any heavy frost, then measure the stabilized freezer temperature.

Will after we get a backup.
There's a ton of meat in the freezer that we don't want to lose if it get's messed up.

Took the rear panel of the freezer off and I wouldn't call it a frost pattern; rather the entire coil is a solid block of ice. What I am calling the coil is the finned tubing running from side to side and I really don't know the appropriate term. Looking around and not seeing anything resembling a heater to defrost. Is it near the coil?

You defrost all the coils with a hair dryer, then you will see the defrost heater and defrost thermostat, a round thing clipped to the coils.

I found the heater tube tucked up under the bottom. The glass on one end has a small frosty colored stain but the wire inside seems to be in tact.
I think I see the thermostat (barrel shaped item?) in the upper right corner but can't imagine how it would be accessed because it's clipped to the back of a copper tubing that seems to be fixed in position.
Can the motherboard cause the heater to not work?

With the compressor running, and the freezer cold, Pull the cover off the motherboard in the back, locate the 3 wire power connector. Unplug fridg and pull off the connector.Place a wire jumper between the connector pins that mate with the motherboard pins line and def.
Plug fridg in. If fridg now defrosts the coils, you have a bad motherboard, if not, you have a bad defrost heater or thermostat.

Thanks,
I'll have to get it back together and give that a try.
In the event that the thermostat needs changing, is there a trick to getting to it and the connections?
