Ошибки кондиционера lg

     Современные кондиционеры оснащены удобной системой диагностики неисправностей. Выявив дефект, сплит-система блокирует свою работу и сообщает на табло о причине поломки. Аппаратура, изготовленная компанией LG, выдает информацию о нарушениях в работе в виде зашифрованных кодов, а также — посредством мигания светодиодных индикаторов. При определенной неисправности светодиоды будут мигать с заданной частотой, повторяя цикл через 3 секунды.
Основные коды ошибок бытовых настенных моделей кондиционеров LG приведены ниже:


F01 – короткое замыкание (либо обрыв) комнатного (room) температурного датчика во внутреннем блоке.


F02 – короткое замыкание (либо обрыв) внутреннего (pipe) температурного датчика во внутреннем блоке.


F03 — нарушение связи между ПДУ и платой управления.


F04 – замыкание датчика температуры (pipe) наружного блока.


F05 – замыкание воздушного датчика (room) наружного блока.


C1 (Ch2, CH01) – поломка связана с терморезистором температуры поступающего воздуха, расположенным во внутреннем блоке.


C2 (Ch3, СH02) – поломка связана с терморезистором температуры, расположенным в наружном блоке.


С3 (Сh4, CH03) — сплит-система в одно и тоже время работает на обогрев и охлаждение.


С4 (Сh5, CH04) – короткое замыкание (либо обрыв) в температурном датчике конденсатора, вследствие чего была активирована система защиты от перегрузок.


С5 (CH5, CH05) – нарушение, связанное с дефектом в обрыве обмена данных между внутренним и наружным частями сплит-системы.


C6 (СH6, CH06) – нарушение, связанное с кратковременным превышением тока потребления в реле наружного блока.


С7 (CH7, CH07) – нарушение, связанное с длительным превышением тока потребления во всем наружном блоке.


С8 (СH8, CH08) – неисправность, связанная с нарушением функционирования двигателя вентилятора внутреннего блока.


С9 (СH9, CH09) – неисправность, связанная с нарушением функционирования двигателя вентилятора наружного блока.


СА — температура нагнетания превышает 130 градусов С.


CD – нарушение работы инверторного модуля.


В некоторых случаях ошибка может появиться в результате случайного сбоя в системе. Выключите и снова включите ваш кондиционер, убедитесь, что ваши пользовательские настройки соответствуют требованиям инструкции. Если ошибка повторилась, обесточьте аппарат и обратитесь в службу сервиса.
