海爾變頻空調因型號不同,E1的含義也不一樣,因氟壓力過低則顯示E1,多數是內機環境溫度傳感器,也有可能是模塊,
以下代碼適用于海爾KFR-48LW/BPJXF、KFR-48LW/BPF、KFR-50LW/BPJXF、KFR-51LW/BPJXF、KFR-51LW/BPJF、KFR-51LW/NBPF、KFR-51LW/TBPJXF、KFR-51LW/BPJXF、KFR-52LW/BPJXF、KFR-52LW/BPJF、KFR-52LW/EBPJXF、KFR-52LW/NBPJXF、KFR-58LW/TBPJXF、KFR-58LW/BPF、KFR-58LW/BPJXF、KFR-60LW/BPJXF、KFR-58LW/BPJXF、KFR-58LW/EBPJXF、KFR-58LW/NBPJXF、KFR-58LW/NBPF、KFR-60LW/BPJF、KFR-60LW/BPXF、KFR-60LW/EBPJXF、KFR-68LW/BPJXF、KFR-68LW/EBPJXF、KFR-68LW/BPJXF等空調。
