What Temperature alarm message
actually means.

On Bosch Benchmark freezer columns the temperature alarm appears as a message on the control panel when the freezer compartment gets too warm. The message includes the warmest temperature reached, which is what tells you whether food softened. Bosch notes the alarm can also come on harmlessly at first start-up, after a large load of fresh food, or when the door was open too long.

What to do when Temperature alarm message shows on the freezer

Kind of codeTemperature and alarms

The freezer measured a cabinet warmer than it should be and said so, sometimes with the highest temperature it reached while nobody was looking. The cause can be as simple as a door left ajar or a long power outage, or as serious as a compressor that stopped. Keep the door or the lid shut and check whether the food is still hard before anything else; the alarm is a warning about the food, not a diagnosis.

Usually leads toFreezer thermostat and temperature control repair

Repairing the dial thermostat or the sensor and control that decide when a freezer cools, so it stops running without end or quitting too early.

Shows up asFreezer Warming Up With Food Inside

The freezer warming up is a race against the clock: frozen packages are softening, drips are forming under the bottom basket, and the question is how long the food can wait.

Before you book,
in this order.

Each step comes from Bosch's own guidance for Temperature alarm message on its freezers. Follow it to the end: the last card says whether this is a visit.

01

Read the warmest temperature in the message and check the food against it.

02

Move anything that thawed to a working freezer or a cooler with ice, or cook it.

03

Fix the obvious cause, such as a door not closed, then press OK to acknowledge the message.

04

Book a visit if the alarm returns with the door closed and no fresh food added.

Still there?

It usually turns into freezer thermostat and temperature control repair. Book with the code and the model number.

What not to do

The temperature alarm is not the door alarm, which has its own message for a door left open. It also does not tell you which part is failing; a repeat alarm needs the fan, defrost and sealed system checked.

Questions
about Temperature alarm message.

Can I clear Temperature alarm message myself?
Read the warmest temperature in the message and check the food against it. If it comes back, it needs a visit.
My new Bosch freezer column showed a temperature alarm on day one. Is it defective?
Not necessarily. Bosch lists first start-up with no food inside as a normal trigger, because the cabinet starts warm. It should clear once the column reaches its setting.
What does the number in the Bosch temperature alarm message mean?
It is the warmest temperature the freezer compartment reached. After you acknowledge the message, the control starts recording a new warmest reading from that moment.
Can a panel that rubs the cabinet cause temperature alarms on a Bosch column?
Yes. If the custom panel or the hinge keeps the door from sealing, warm air leaks in and the alarm follows. Hinge and panel adjustment are part of the visit.

Back to your everyday

Still showing Temperature alarm message?

Book with the code or the alarm pattern written exactly as the freezer shows it, the full model number, and whether the food is still frozen hard — when there is a code, that is where the diagnosis starts.
