The detected error is an oil level detective temperature sensor error. Check disconnection of the wiring and resistance<br />
value of the sensor.<br />
If the sensors are normal, replace the outdoor I/F P.C. board.<br />

Sensor error<br />
Start a test operation in COOL or HEAT mode.<br />
↓<br />
Display TK1 sensor temperature on 7-segment display with<br />
SW01/02/03=[1] [12] [2].<br />
↓<br />
Check TK1 sensor temp approx. 10 minutes after compressor 1 has operated.<br />
If low temperature continues (approximately outside temp) or temperature has<br />
little change, a clogging of strainer of oil-equalization circuit, clogging of<br />
capillary tube, or malfunction of check valve is considered.<br />
No error<br />
