Display
TK2 sensor temperature on 7-segment display with
SW01/02/03=[1] [13] [2].
↓
Check
TK2 sensor temp approx. 10 minutes after compressor 1 has operated.
If low temperature continues (approximately outside temp) or temperature has
little change, a clogging of strainer of oil-equalization circuit, clogging of
capillary tube, or malfunction of check valve is considered.
