Bosch Refrigerator r1 Marks a Fresh Food Probe With No Usable Signal

What r1 means

Every Bosch French door refrigerator has a probe watching the fresh food side, and r1 says that probe's signal is gone. The manual describes two states: Lo for a broken connection and Hi for a short. To confirm, a technician unplugs connector CN15 at the main board and measures resistance. If the reading is open or shorted, the manual's answer is a new sensor for the refrigerator compartment.

Common causes of r1

Probe in the fresh food section that has gone open-circuit or shorted
Plug at the board that is not fully seated
Cable damaged where the harness runs through the cabinet wall

✓ One safe check you can try

1. Start at the rear wall of the fresh food section and move away anything leaning on it. 2. Check the air vents and clear them of containers. 3. Leave the unit to settle for a day, since blocked air can produce signs that mimic a sensor problem. 4. If r1 is still displayed after that, call us.

! Why to stop there

Measuring at CN15 means reaching into the board area, which is no job for a plugged-in refrigerator.
Damaged cabling inside the cabinet can pass for a dead sensor, and a new sensor will not cure it.
Pulling panels to get at the harness can crack plastic parts that are costly to replace.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

r1r1 questions

What is r1 telling me about my temperatures?

Nothing dependable at all. The probe reads open or shorted, so the control does not know how cold the fresh food section really is. That sensor reading drives how the compartment is cooled.

Could my produce spoil?

It could if the section runs warm. Keep a thermometer inside and aim to stay below 40F for perishables until we have repaired it. Spoilage is the main risk here.

Will you replace the whole control board?

Not unless testing shows the board itself is the cause. The manual's remedy is the sensor, so we begin there, and you see a written price first.
