E17 error; unit may indicate a general sensor bus or multiple sensor failure.

Safety first: Disconnect power before inspecting wiring or sensors.

• Step 1 – Visual harness inspection: Locate the main sensor harness running from the evaporator and bin area to the control board. Look for pinched, cut, or melted sections.
• Step 2 – Reseat connectors: Disconnect and reconnect all sensor-related connectors at the board and in the cabinet, ensuring firm seating.
• Step 3 – Isolate faulty sensor: If possible, disconnect sensors one at a time (evaporator thermistor, bin thermistor, ambient thermistor) and power up to see if E17 clears. The sensor that, when disconnected, clears the code is likely shorted.
• Step 4 – Replace bad sensor or harness: Replace any sensor that appears damaged or tests out of range. If the harness is damaged, replace the entire harness assembly.
• Step 5 – Control board replacement: If all sensors and wiring are good but E17 persists, the control board sensor bus circuitry may be defective and require replacement.
