Error codes for Mitsubishi Heavy cylinders and air conditioners

Mitsubishi Heavy air conditioners often report flashing lights. Please base on the error message below to determine the condition of the air conditioner and find a suitable solution:

1. Flash light 1 time : The indoor unit is damaged, the sensor is broken, the connection is poor
2. Flashes twice : Temperature sensor error
3. Flashes 5 times : Error of voltage filter, outdoor circuit board
4. Flash lights 6 times : Faulty cold motor motor failure or bad connection.
5. Flashes continuously but only once : Sensor error on the outdoor unit, the outdoor unit board has trouble.
6. The lamp flashes continuously for 4 times : Compression line sensor does not work well.
7. Timer light flashes once : Blocked muscle, Power Transtor is touched
8. Timer light blinks twice : Error of outdoor unit, block
9. Timer light blinks 3 times : Residual gas or components are touched
10. Timer light blinks 4 times : Power Transistor error
11. Timer light blinks 5 times : Lack of gas, unopened gas valve, sensor failure path.
12. Timer light blinks 6 times : Signal line fault, indoor unit board : 
13. Timer light blinks 7 times : Error of outdoor unit fan, signal line, broken board.
