Karachi mein voltage fluctuations aur load shedding AC ka PCB (Printed Circuit Board) sabse zyada damage karte hain. PCB AC ka brain hai — agar yeh kharab ho jaaye toh AC completely behave karna band kar deta hai. Is guide mein hum PCB fault ke symptoms, causes, aur repair options cover karenge.
AC PCB Fault Ke 6 Clear Symptoms
1. AC On Hi Nahi Hota
Remote se command dete ho lekin AC completely dead hai — no beep, no light, no response. Power supply check karo pehle — agar power theek hai toh PCB fault likely hai.
2. Random Error Codes
Hitachi AC mein E1, E3, E5, E6 aur Sharp mein EE, E0 error codes PCB problem indicate karte hain. Error code dekhte hi AC band ho jaata hai.
3. Cooling Nahi Lekin AC On Hai
AC chalta hai, fan bhi chalti hai, lekin thandi hawa nahi — compressor signal nahi milta PCB se. Yeh common PCB fault hai especially after power surge.
4. Remote Response Nahi
Remote change kiya, batteries change ki, phir bhi AC respond nahi karta — receiver circuit on PCB faulty ho sakta hai.
5. AC Suddenly Off Ho Jaata Hai
Kuch minutes chalne ke baad AC khud band ho jaata hai — thermal protection ya capacitor fault on PCB. Karachi ki garmi mein yeh problem peak season mein zyada aati hai.
6. Burning Smell After Power Outage
Load shedding ke baad AC on karo aur burning/plastic smell aaye — PCB ka koi component burn ho gaya hai. Immediately band karo aur technician bulao.
