Mitsubishi central air conditioning panel display 03

System high voltage protection

Mitsubishi central air conditioning panel display 03 usually indicates system high voltage protection. In this case, the air conditioner may be abnormal, not working, and not starting.

There are several workarounds:

1. First of all, exclude external factors, such as evaporator, condenser dirty, power supply shortage, etc. If the machine shows E1 as soon as it is turned on, you need to check whether the compressor is started, if it is not started, the high voltage switch will be measured, and if it is started, the compressor starting current will be measured.

2. If the machine is on for a period of time and shows E1, you need to check the high-voltage switch and circuit.

3. If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for testing.
