9、第一步先判斷是控制故障還是系統(tǒng)故障，可先把室內(nèi)管溫包從蒸 發(fā)器中取出，如果不出現(xiàn)，則說明是系統(tǒng)問題；第二步檢查室內(nèi)環(huán)境溫度是否太低，室內(nèi)風(fēng) 機轉(zhuǎn)速是否太低，室內(nèi)蒸發(fā)器是否太臟，系統(tǒng)是否堵塞。5.開機顯示故障代碼 E2:室內(nèi)管溫器斷路，造成誤保護。 6. 運行一段時間壓縮機、室外風(fēng)機停止，室內(nèi)風(fēng)機仍運轉(zhuǎn)，顯示 故障代碼E2（燈箱型無顯示）：（1）檢查蒸發(fā)器是否結(jié)霜，若結(jié)霜，則顯示故障代碼E2。其結(jié)霜原因可能是:1） 系統(tǒng)缺氟， 可用壓力表測系統(tǒng)壓力、 用鉗表測運行電流， 低壓偏低或電流偏小，則需加氟。2）氣溫偏低（25C以下）時，制冷運行蒸發(fā)器可能會結(jié)霜。3）蒸發(fā)器表面臟，風(fēng)量小。（2 ）如蒸發(fā)

10、器未結(jié)霜，則可能是室內(nèi)管溫頭位置不對，造成局部溫度過低，可將管溫頭移出再試。(3)室內(nèi)管溫感溫包壞或折斷。(4)也可能是顯示器本身故障或控制板問題。(5)過濾網(wǎng)太臟。(6)系統(tǒng)臟堵。(7 )室內(nèi)電動機轉(zhuǎn)速太低。E2: in door evaporator an ti-freeze protecti on.Possible causes: Error code E2: the first step is to determine fault or controlsystemfailure, the in door pipe temperature can first be removed fro
