I have a Thermador KBUIT4265E 03 refrigertor/freezer. The temperature set points lights are blinking and there is a constant chirping or pinging sound from the compressor compartment above.

There are plenty of reasons this could happen like the following: PROBLEM POSSIBLE CAUSE Loud operating sound level • See "Sound Information" section for explanation of normal operating sounds Freezer too warm. Compressor not operating • Freezer temperature set too warm • Defective compressor • Defective overload or relay Refrigerator too cold • Refrigerator temperature set too cold • Chefs Pantry control set too cold or misaligned allowing freezer air to escape into refrigerator section • Freezer temperature set too cold • Restricted condenser air • Refrigerant shortage or restriction • Refrigerant overcharge Freezer too warm. Compressor cuts off on overload • Heavy usage • High ambient • Restricted condenser air • Defective condenser fan motor • Loose or missing condenser fan blade • Improper voltage • Defective relay or overload • Compressor motor winding • Non-condensibles in system • Refrigerant overcharge Freezer too warm. Compressor operating • Freezer temperature set too warm • Restricted condenser air • Defective condenser fan motor • Opened door • Heavy usage • Defective freezer fan motor • Opened defrost thermostat • Opened defrost heater • Loose or missing freezer or condenser fan blade • Heavily frosted evaporator • Refrigerant shortage or restriction • Inefficient compressor Refrigerator too warm • Refrigerator temperature set too warm • Freezer temperature set too warm • Return air or air supply duct blocked • Chefs Pantry control set too warm or air supply tube blocked • Heavy usage • High ambient Problem Possible Cause Freezer too cold • Freezer temperature set too cold Long off cyde • Low ambient • Freezer temperature set too warm Short off cycle • Heavy usage • High ambient • Freezer temperature set too cold • Light constantly on • Poor door gasket seal Long or continuous run cyde • Heavy usage • High ambient • Inadequate condenser air flow • Freezer temperature set too cold • Loss or restricted refrigerant Short run cycle • Light usage • Low ambient • Freezer temperature set too warm Exterior cabinet condensation • High humidity. Design accepts beads of water on cabinet exterior after 4 hours with 0° to 2°F (-18° to -17°C) freezer food temperature and 38° to 40°F (3° to 4°C) refrigerator food temperature in 84% R.H. conditions. See "Typical Sweat Pattern" section under above conditions. • Freezer temperature set too cold • Poor door gasket seal • Insulation void

The blinking light may be notifying you that the water dispenser solenoid valve has failed.

You bought a Fancy fridge, now pay a Fancy technician to fix it...
Trying to own Thermador appliances on a budget is not possible nor is it intelligent.

What Is the model number? You need a service tech that can fix the problem because it is serious APPLIANCE 911

Temperature alarm
If the temperature becomes too warm, an alarm will sound and the temperature display will flash. The temperature the appliance is set at will determine when the alarm is triggered.
The alarm will sound and the display will flash under the following conditions:

• - whenevertoomuchwarmairflows into the appliance, for example when food is being loaded, re-arranged, or taken out.
• - wheneverlargeamountsoffoodare being frozen at once.
• - whenevertherehasbeenalengthy interruption of the power supply. Door alarm
  If the appliance door is left open for longer than approx. 60 seconds, the alarm signal will sound.

Switching the alarm system ON
The alarm system is always active. It does not need to be switched on manually.
Switching the alarm OFF early
Once the set temperature has been reached in the freezer section, the alarm signal stops and the temperature display stops blinking. If the alarm signal bothers you, it can be switched off early.
^ Press the alarm off button. The alarm signal will stop. The temperature display will continue to blink until the set temperature has been reached. The display then stops blinking, and shows a steady reading. At this point, the alarm system is ready again if needed.

most icemakers have a metal rod mounted to the side of the unit. this is a "ice level shutoff. in the raised position its off.. in the dowm position its on..try that.. it may be off..

Sounds like a probe fault. It should stop freezing when the set point is reached and defrost for a short while. Have you set it to fast freeze?

The water inlet valve is jammed open.You need to turn the water off at the main's & then get someone out to replace the inlet valve.GOOD LUCK

it has to get down to the proper temperature after the reset the set point is -4 for the freezer and 38 for the refrigerator. the numbers shown o\n the digital display panel stands for the actual temperatures. When the compartmnet tempertures go down, so do the numbers on thge display panel, and finally they reach the set temperatures. Once the system is stabilized , the display tempoeratures are the set temperature.
