Dixell iChill flashing AL11, buzzer on — rack keeps cutting out

AL11 — condensing pressure above the high-alarm setpoint The IC100CX trips the general alarm relay and cuts the compressor to protect the circuit. Work through these in order: 1. Condenser coil — fouled or blocked? 2. Condenser fans — all running, correct rotation? 3. Ambient at the condenser — heat trapped? 4. Recently serviced? Check overcharge / non-condensables

coil was packed with dust — cleaned it, pressure's dropping

That matches: a fouled coil can't reject heat, so head pressure climbs until AL11 trips. Reset the alarm and watch it through one full cycle.
