I have an Amana side by side fridge freezer and the fridge

This answer was rated:

I have an Amana side by side fridge freezer and the fridge temperature has gone haywire, going down to -7 then slowly reversing.

If you remove the baskets in the freezer in the lower half look on the back wall and see if theres any ice or frost on the back wall there and let me know.

No ice or frost on back wall

Ok what you need to do if you can is empty the freezer section andremove the back panel inside the freezer.
From there you will see the evaporator. Check to see if this is blocked up with ice.

As when you get a fault with the freezer dropping down to arund -7 degs it can be down to air flow. A blocked evaporator can cause this.

If theres no ice on there then have a look at it and see if theres an even layer of frost all round the evaporator and let me know.

So I have to unscrew all the back panels in the freezer?
Yes theres only a few screws that will be holding it on.

Don't have pliers small enough to unscrew the small nuts holding the freezer panels, neither does neighbour. Could the fluctuation in fridge temp be down to anything else before I attempt to take the freezer panels off tomorrow?

It can be either a blocked evaporator with ice. But if thats ok then its possibley the compressor at the back. As these can fail on these appliances. The compressor part isnt a diy fix im afraid as it involves cutting the pipe work and letting the gas out. Then it will need to be regassed so this is a job for a fridge engineer.

But as to the evaporator. If you dont have the tools to remove the panel what you can do is empty the appliance and turn it offfor 24 hours and leave the freezer door open. This will allow the ice to melt in there. Then turn it back on and see how it goes. It it goes stright down to -18 and stays there then it was a blocked evaporator so should only take about 4 hours to get to -18 after turning it back on.

But if after this its still not working correctly then its possibley the compressor at the back at fault im afraid.
