อยากจะคัดลอก ไปลง เวปอื่น  กรุณา ให้เครดิต เวปนี้ด้วยครับ  ขอบคุณ

 ของผม  ใช้LG     ขื้น c2      :D :D :D

มือใหม่ครับผม แล้วรหัสต่างๆที่ว่านี้เราดูจากที่ไหนครับ เพราะแอร์ส่วนมากไม่มีจอบอกสถานะ
รบกวนท่านผู้รู้ครับผม  thank2

ถ้าไม่มีหน้าจอ ก็ดูที่การกระพิบของหลอดไฟ
ถ้ายี่ห้อของท่านไม่มีในนี้ก็โพสถามได้ครับ  ถ้าผมมีข้อมูลก็จะลงให้ครับ

 :D

มันขึ้น rE ครับ

ขอ CARRIER Error codeด้วยครับ

ขอรหัสของยี่ห้อ Saijo Denki ได้มั้ยครับถ้ามี ขอบพระคุณล่วงหน้าครับ cry2!!

 smiley4 มีประโยชน์มาก ขอบคุณมากครับ

เช็คโค๊ดErrerไดกิ้น : กดปุ่ม Cancel ค้างไว้10 วิ จะขึ้นตัวเลข 00
                                    ให้กดปุ่ม Cancel ไปเรื่อยๆ จะได้ยินเสียงปี๊บสั้นๆ ในแต่ละโค๊ด
                          หากพบโค๊ดที่ Er จะมีเสียงปี๊บยาว (นั้นแหล่ะใช่เลย)
ยี่ห้ออื่นเดี๋ยวค่อยทยอยลงละกันนะครับ (ขอโทรไปถามศูนย์ก่อง) embarrassed7
   

ขอสอบถามหน่อยครับแอร์ซัมซุง อินเวอร์เตอร์เครื่อง12000  อาการโชว์E1 ขอบคุณครับ

ระบุรุ่นของ แอร์ ด้วยครับ

ระหัส Error แอร์ Mitsubishi

สุดยอดไปเลยครับ tongue3

แอร์เซ็นทรัลครับ
ขึ้น E3 คืออะไรครับ
รุ่น CFW-ZF43/CCS-ZF13

ผมไมีมีข้อมูลตรง     แต่ใช้การอ้างอิงจากหลายยี่ห้อที่ผมมี
E3  เป็นไปได้ว่า เกิดจาก ตัวเซนเซอร์คอยล์เย็น (ตัวที่เสียบกับแผงคอยล์เย็นเสีย)
ทดลองเปลี่ยนดูก่อนครับ   ได้ผลอย่างไร เอามาแชร์กัน   จะได้เป็นฐานข้อมูล ให้ ช่างท่านอื่น ที่เข้ามาอ่าน    ได้เป็นวิทยาทาน   

ขอบคุณมากครับ lv! lv! lv!
