Miele Refrigerator Error Code F116

F116 indicates that the freezer evaporator NTC temperature sensor is reporting a faulty reading. Specifically, the sensor's resistance corresponds to a temperature below -66°F (-55°C) or above 140°F (60°C), both of which fall outside the physically plausible operating range. This prevents the control board from accurately managing freezer cooling cycles. The fault points to either a failed sensor, a wiring issue, or a connector problem.

The F116 fault means the refrigerator is operating without reliable freezer temperature data, which can lead to improper cooling or compressor behavior. Food safety may be at risk if the freezer is not maintaining proper temperatures. It is advisable to check that the freezer is still holding adequate temperature and to arrange for repair promptly rather than continuing to rely on the unit without addressing the fault.

A reset may temporarily clear the F116 code from the display, but the fault will return if the underlying sensor or wiring problem has not been corrected. The control board continuously monitors the NTC resistance and will re-trigger the error as soon as it detects an out-of-range reading again. Resetting without repairing the root cause does not restore reliable freezer operation.

A knowledgeable DIYer can inspect the wiring harness and connector for visible damage, corrosion, or loose pins and may be able to resolve the fault without parts. If the wiring checks out, replacing the freezer evaporator NTC sensor is the recommended next step. However, accessing the evaporator area typically requires removing freezer panels, so comfort with appliance disassembly is helpful. If you are unsure, a qualified technician can diagnose and replace the sensor efficiently.

If only the NTC sensor needs replacement, parts and labor typically fall in the range of $100 to $250, depending on the specific model and local labor rates. If wiring repairs or connector replacement are also needed, costs can increase modestly. Control board replacement, if required, would be a more significant expense, generally ranging from $300 to $600 or more for parts and labor.
