Hello, I recently picked up a fridge from my parents that wasn't working, (Fridge Side). I plugged it in, both sides cooled down to acceptable degrees (0 and 38). But with what my parents have told me, I believe the unit will "ice over" sooner rather than later. Any suggestions would be great. I have read quite a bit about Temp Sensor, Thermo Fuse, or even the heater. Thanks, Joe

Check for ice build-up in and around the freezer fan where the blades are, if you can see ice in there (some times it may look like white foam but dont be fooled, it will be ice), the fan will be hitting it, defrost the freezer and check defrost element, (you will have to dismantle freezer section to get to it but reletively simple job) disconect from mains first. Good luck

Fan unit or defrost element has failed, usually the defrost element, not a hard DIY, just be very careful. Check fan is running first and that it is not part of the new icy growth inside the freezer, regardless, you will need to defrost this glacier first before you can do anything and PLEASE dont resort to a blow torch, there is plastic and pressure gas in there. Just be patient and watch the fins on the cooling unit, you could shave with that stuff. Good luck, any probs, call me on 08 9523 0552. Russ

Hi,
Let's start by diagnosing the freezer;
Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.
It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.
Several other problems could be keeping your freezer from freezing:
There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.
If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.
The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.
If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.
Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food
As for the fridge, the same solution but for more details. If refrigerator is not cooling properly can be due to a defrost timer, which is causing the fridge to go into defrost cycle. Usually it takes 45-60 minutes for refrigerator to come out of defrost cycle. If the timer goes bad then it will not come out of defrost cycle and can result in this kind of issues. It can also occur due to defrost thermostat, it allows current to pass through it at temperatures of 20 to 30 degrees Fahrenheit and prevents current from passing through it at 40 to 60 degrees. This is difficult to test, though, because it takes a prolonged, very-cold temperature to turn it on. The defrost thermostat is snapped onto the top portion of the evaporator. The thermostat sends temperature information to the processor. The defrost heater must be replaced when replacing the thermostat.
1. Remove the lower fan duct work from the evaporator cover.
2. Remove the 1/4-in. evaporator cover screws and remove the evaporator cover.
3. Disconnect the defrost thermostat wiring connector.
4. Remove the defrost thermostat from the evaporator.
I hope the above helps.......
Regards.
Compressor should rapidly bring pressure down from standing pressure to running pressure when switched on. If no change, compressor not pumping. Make sure the line tap valve isn't leaking, and the gas you used was correctly charged.

Sounds more like compressor failing to pump than board fault
