Possible Causes

How to Fix / Troubleshooting
Safety first: Turn off power before accessing the indoor PCB area.
- Step 1 – Identify sensor: On models with built-in humidity or additional sensors, locate the small sensor module near the air intake or PCB.
- Step 2 – Check connection: Ensure the sensor plug is fully seated on the indoor PCB and the wires are not damaged.
- Step 3 – Replace sensor module: If the sensor is suspected faulty (e.g., shows unrealistic humidity), replace it with a Toshiba-compatible sensor module.
- Step 4 – PCB check: If a new sensor does not clear E15, the indoor PCB may have a defective sensor input and require replacement.
