Bosch Refrigerator Error E19 — What It Means & How to Fix It

What Does This Error Mean?

Error E19 means the condenser fan motor is not running or is running too slowly to cool the compressor. Without condenser airflow, the compressor overheats and shuts down — your refrigerator will stop cooling entirely. This is a critical fault — food will spoil within hours if the fan is not repaired.

Affected Models

Bosch Serie 6 KGN86AIDR
Bosch Serie 4 KGN39VXBT
Bosch French Door B36CT80SNS
Bosch Counter-Depth B11CB81SSS
Bosch Serie 8 KGN86AIDP

Common Causes

Condenser fan motor bearings worn out causing the motor to stall under load
Debris or dust buildup on the fan blades preventing them from spinning
Fan blade physically obstructed by a foreign object behind the refrigerator
Wiring fault or failed capacitor cutting power to the fan motor
Main control board relay failed and no longer supplying voltage to the fan

How to Fix It

Unplug the refrigerator immediately to prevent further compressor overheating.

Running the compressor without condenser airflow causes rapid overheating — every minute counts once E19 appears.
Pull the refrigerator away from the wall and remove the rear access panel to expose the condenser fan.

The condenser fan is located at the bottom rear of most Bosch models, next to the compressor.
Clear any dust, pet hair, or debris from the fan blades and condenser coils using a vacuum or soft brush.

Heavy dust on the condenser coils makes the fan work much harder — this is a common cause of motor failure over time.
Spin the fan blade by hand to check if it rotates freely.

If the blade is stiff, grinds, or wobbles, the motor bearings have failed and the motor must be replaced.
Test the fan motor winding with a multimeter — check for continuity and correct voltage at the connector.

A motor with an open winding reads OL on continuity mode and must be replaced even if the blade spins freely.
Replace the condenser fan motor with a Bosch OEM part matched to your model, reassemble, and restore power.

Allow 30 minutes after repair for the compressor to reach operating temperature and for cooling to resume.

When to Call a Professional

Call a technician immediately if you cannot access or replace the condenser fan yourself. Condenser fan motor replacement typically costs $100–$250 in parts and labor. Do not leave the refrigerator running without a working condenser fan — compressor damage will follow quickly.

Frequently Asked Questions

How quickly will food spoil if I have E19 on my Bosch refrigerator?

Without condenser cooling, the compressor will overheat and shut off within 1–2 hours. Once the refrigerator stops cooling, perishables become unsafe after 4 hours. Transfer food to a cooler with ice immediately while you arrange repairs.

Can a dirty condenser fan cause E19 without the motor actually failing?

Yes — heavy dust buildup on the fan blades increases motor load until it overloads and stalls. Cleaning the condenser coils and fan blades sometimes resolves E19 without any parts replacement. Clean the condenser area at least once a year to prevent this.

Is E19 covered under a Bosch refrigerator warranty?

If your refrigerator is within the standard 1-year parts and labor warranty, yes — contact Bosch at 1-800-944-2904. For out-of-warranty units, the fan motor and labor cost roughly $100–$250 through a certified technician. Extended warranty plans (if purchased) typically cover this repair.
