Siemens fridge freezer keeps sounding the alarm but freezing up

I do not believe the problem is the fan. sounds like the frig. is low on Freon this is what will cause the ice build up. you need to find the leak, you can do this by spraying soapy water on coil tubes & watch for bubbles. repair leak & recharge.

There could be an ice build up sensor on the coil. try turning it off and using a hair dryer to melt any ice on the coil. This would be inside the rear of the freezer, you would direct the hot air into the vent that the cold air normally comes out of.

Sounds like the defrost system of your freezer is not working. It could be either the defrost timer, defrost thermostat or the heater has a problem. The defrost timer turns off the compressor periodically to sent power to the defrost heater via the thermostat. The defrost heater then powers up and heats the evaporator coil to melt the accumulated ice buildup on the cold coils. Most likely issues are that the timer motor is not advancing the timer or the heater itself has burned out.

Hi,
As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...

Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

If you are not capable to do that much better to call service Engineer to avoid big damage of your Freezer.

more than likely the defroster inside the freezer has gone bad. This defroster is located in the space between the fridge and freezer and activates to defrost the freezer and stop build up of ice in the freezer.. If it is bad the freezer will not keep the fridge nor freezer cold.

Check to condenser coil and make sure it is clean and the fan near it is running when the compressor is on. Check for ice build up in the freezer. If the evaporator coil is iced up the box will run warm. It may be a defrost problem, a dirty condenser, or a refrigerant issue.

I turned the fridge and freezer off using the circular dials, I then turned the unit off at the mains. Left it for a few minutes and then turned the power back on. I then turned the circular dials to "max" and then depressed the super cool and super freeze buttons to turn this facility on. This time they came on normally (not flashing) and no alarm sounded. The fridge and freezer then started to get cold. Once the unit had been running for several hours I then turned the dials to the 3/4 mark and depressed the super cool and super freeze buttons again to turn them off. Over night the fridge and the freezer appear to be working properly so I hope that my problem is solved. Maybe the unit just needed to "settle" before being switched on?

The ice builds up in the freezer compartment because the defrost cycle is not working. Check the timer , the defrost elements the defrost thermodise.
God Bless.

Sounds like a blocked defrost drain. By "American" I presume you mean side-by-side.
I had a similar problem with a freezer-on-top style Samsung. The solution to that was to defrost the freezer, remove the false backing plate in the freezer (required removal of the ice cube tray. the panel just pops out with a bit of pulling). The drain hole beneath the freezer coils was blocked with ice. This drain passes down into the fridge and then out the back of the fridge into the evaporation pan next to the motor. There is a collector pan under the freezer coils, this and the drain hole were filled with ice. When the freezer goes into its self-defrost cycle the water collects here and then overflows into the fridge.
I removed the ice with hot water/vinegar mixture (so it doesn't re-freeze immediately) and simultaneosuly used a bit of chiselling with a screwdriver to clear the drain plug. I did this from inside the fridge working up the drain hole into the freezer. The whole job took about an hour.
