Lennox 54M89 Control Kit 30067439-890 signs of terminal leakageThe Lennox 54M89 Low Ambient Control Kit (LB 101123B) is a critical field installed accessory designed to maintain head pressure in PSC fan heat pump units during cooling cycles in low temperature environments. This kit enables reliable system operation down to 30F ( 1C) by cycling the outdoor fan via the S11 pressure switch. By regulating fan operation, the kit preserves the necessary pressure differential across the expansion device, preventing
