Question:

What is the reason of the high pressure alarm on the compressor?

The filter is clogged. The capillary is blocked. Is that possible? The compressor is broken. Is it possible to turn on the alarm for one second?

Answer:

Filters and capillary clogging may cause compressors to report low voltage or high voltage failures, but the failure time is not so fast. It may take dozens of seconds! The main reasons for the high voltage failures are: poor cooling effect of the condensing fan, excessive refrigerant and damage to the high voltage protector
The filter is blocked or the possibility of capillary blockage is great! I've encountered a clogged filter. That's the case. It's normal to change the filter!
If the boot is estimated within one second high pressure alarm, fault line, if the boot 3-5 seconds alarm, high voltage protection may be broken, or lowered the protection value, if the boot 10 seconds is estimated to be high pressure, condenser fan does not start, the cooling water flow, if more than 20 seconds before the alarm, should be the heat is not good. Of course, it is possible that the high voltage protection is broken or the protection value is lowered.If you use 407C refrigerant, there may be too high environmental temperature, water outdoor machine, once the machine is good.
