• Yaskawa A1000 oL2 Fault - Causes & Fix

  10 Jun, 2026

  oL2 on a Yaskawa A1000 means inverter/drive overload. The drive protected itself from overheating. Most often caused by heavy load.

• Yaskawa A1000 oL1 Fault - Causes & Fix

  10 Jun, 2026

  oL1 means motor overload: the drive's thermal protection tripped. Most often caused by too-heavy load or incorrect motor current settings.

• Yaskawa A1000 VFD oL Fault - Causes & Fix

  10 Jun, 2026

  oL fault means motor or drive overload. Most often caused by excessive mechanical load. Check load, verify motor parameters, and inspect for binding.

• Yaskawa A1000 oH Fault Code - Causes & Fix

  10 Jun, 2026

  oH means heatsink overheat on your Yaskawa A1000 VFD. Most often caused by restricted airflow or a failed cooling fan blocking heat.

• Yaskawa A1000 oC Fault - Causes & Fix

  10 Jun, 2026

  oC means overcurrent at the output: the drive detected current beyond its limit. Most often a mechanical overload or motor cable fault.

• Yaskawa A1000 LF3 Fault - Causes & Fix

  10 Jun, 2026

  LF3 on a Yaskawa A1000 means output phase loss 3: one phase from drive to motor is missing. Check motor cables for loose or open wires.

• Yaskawa A1000 LF2 Fault - Causes & Fix

  10 Jun, 2026

  LF2 on a Yaskawa A1000 means output current imbalance or missing phase. Most often caused by loose output terminals or damaged cable.

• Yaskawa A1000 LF Fault - Causes & Fix

  10 Jun, 2026

  LF means output phase loss: the drive detects missing or unbalanced motor output phases. Check output wiring and terminals first.

• Yaskawa A1000 CPF19 Fault - Causes & Fix

  10 Jun, 2026

  CPF19 is a CPU error in the control circuit. Power-cycle the drive first. If the fault returns, replace the control board or the drive.

• Yaskawa A1000 CPF16 - Causes & Fix

  10 Jun, 2026

  CPF16 signals a control circuit self-diagnostic error. Most often caused by a failed control board. Replace the logic board or drive.

• Yaskawa A1000 CPF14 Fault - Causes & Fix

  10 Jun, 2026

  CPF14 on a Yaskawa A1000 means a control circuit fault caused by CPU error. Power cycle first. If it returns, replace the control board.

• Yaskawa A1000 CPF13 - Causes & Fix

  10 Jun, 2026

  CPF13 on a Yaskawa A1000 is a control circuit fault from internal self-diagnostics. Power cycle the drive, then inspect the operator connector or replace the control board.

• Yaskawa A1000 CPF12 Fault - Causes & Fix

  10 Jun, 2026

  CPF12 means internal control-board memory or CPU failure. Most common fix: cycle power once, then replace the control board if fault returns.

• Yaskawa A1000 CPF11 Fault - Causes & Fix

  10 Jun, 2026

  CPF11 is a RAM fault in the A1000's control circuit. Most common fix: power-cycle the drive, then replace the control board if it returns.

• Yaskawa A1000 CPF08 - Causes & Fix

  10 Jun, 2026

  CPF08 means faulty connection between terminal board and control board. Most common fix: de-energize, reseat the connector, replace board if needed.

• Yaskawa A1000 CPF07 - Causes & Fix

  10 Jun, 2026

  CPF07 on a Yaskawa A1000 means terminal-board communication error. Most often fixed by re-seating connections and cycling power.

• Yaskawa A1000 CPF06 - Causes & Fix

  10 Jun, 2026

  CPF06 is an EEPROM memory data error on the Yaskawa A1000 VFD. The most common fix is replacing the control board after reseating connections.

• Yaskawa A1000 CPF04 - Causes & Fix

  10 Jun, 2026

  CPF04 signals a control-circuit self-diagnostic error. Power-cycle the drive first. If the fault returns, replace the control board.

• Yaskawa GA800 A.145 - Causes & Fix

  10 Jun, 2026

  A.145 is not a valid GA800 fault code. Check the display for a misread parameter number or a 3-letter fault (OC, UV, LF). See real codes.

• Kenmore Oven F2 Error Code - Causes & Fix

  10 Jun, 2026

  F2 means oven overtemperature or sensor fault (varies by model). Most likely: failed temperature sensor or loose wiring.

• Kenmore Oven F10 Error Code - Causes & Fix

  10 Jun, 2026

  F10 means runaway oven temperature detected. Most often caused by a failed temperature sensor; test it for ~1,100 ohms at room temp.

• Kenmore Oven F1 Error Code - Causes & Fix

  10 Jun, 2026

  F1 means control board or keypad failure. Most often the oven control board has failed and needs replacement or repair.
