My Bosch Fridge Freezer Model No: KGS72320GB/01 has a problem on the Fridge section. With the temp set at 4 the light flashes almost continuously and the fridge remains above temperature for most of the time. Sometimes it does get down to nearly the right temperature and the light becomes steady, but this is now infrequent. Would buying and fitting a new control panel put this right. The freezer is working correctly.

The temperature sensor is here, one for each section by the looks of it. Are you going to risk $100 $160 that is doesn't just need a top up of gas?

There are no instruction videos which is unusual.

If this is a frost free model, it could well be frozen up, or the circulation fan could be faulty.

raise the thermostat setting to around 4 -5

Please begin with a Make and model number found around the fresh food section door. Thank you, John Tripp

Is your circulating fan working?
Sometimes they stick and need a shot of WD 40 and then work
it back and forth a little until it wants to take off again. Keep me informed
and PLEASE give a Thumbs Up for the effort. The Raz Shack

Sorry, no secret. The fan wasnt working so we called an engineer who bypassed a sensor. Now it works perfectly again.

I have the same freezer and get the same problems. Ice forms on the refrigeration fins beind the plastic shroud at the rear and completely blocks the airflow. The fan that moves cool air around does not work then and freezer temp goes up. Ice will often push the shroud forwards so that the door does not close properly. Warm moist air get in and just increases the ice problem.

I take the shroud and fan housing off the rear (4 screws and a wire to the fan) and defrost thoroughly using a hair dryer. You can then see when all the ice has gone..

This is a Solution posted by a guy called Sandy Small in october 2005 and believe or not it works

Repair to Bosch fridge freezer KGV3104GB

This MIGHT be the same as yours!

Detach top panel above fridge door and "hinge" it down towards you attached to its connecting wires. See if the connector on the right has a thick black wire (nearest the fridge) and two brown wires. The faulty fridge temp. sensor can be shorted out by connecting the black wire to the brown wire next to it. I managed this by bridging the corresponding points on the PCB with a blob of solder. My fridge freezer works OK now on the freezer sensor. Hope this works with yours!
