ERR5 indicates a temperature sensor or heating element malfunction in your Asko oven. This error prevents the oven from maintaining proper cooking temperatures and requires diagnostic attention.
• Oven fails to heat or heats inconsistently
• Temperature display fluctuates or shows incorrect readings
• Oven shuts off during cooking cycles
• Error code ERR5 appears on the digital display
• Oven beeps repeatedly and locks out operation
• Inability to start any cooking mode
• Temperature may spike or drop unexpectedly during preheating
🔧
Possible Causes
• Faulty temperature sensor (thermistor or RTD probe) in the oven cavity
• Broken or damaged heating element connection
• Corroded or loose sensor wiring harness
• Control board failure preventing temperature regulation
• Damaged oven door seal allowing heat loss and sensor confusion
• Defective door latch switch sending incorrect signals
• Overheating protection circuit triggered by internal temperature spike
• Power supply voltage issues affecting sensor readings
✅
Safety Checks You Can Do
• Power cycle the oven by unplugging it from the wall outlet for 60 seconds, then plug back in
• Verify the oven door is fully closed and latches completely
• Check that you've selected the correct cooking mode for your intended task
• Ensure the kitchen outlet provides stable power and is not overloaded
• Allow the oven to cool completely if it was recently in use
• Visually inspect the oven door gasket for gaps, tears, or poor sealing
• Remove any aluminum foil or cookware blocking interior vents
• Confirm no obstructions are inside the oven cavity blocking air circulation
• Try a simple bake cycle at a low temperature (300°F) to test basic function
• If error persists after these steps, contact Asko USA customer service or a certified technician for professional sensor/heating element diagnostics
