hello,
it could be just extreme heat related...see the following
Compressor will detect signal of module protection right away after it starts. Compressor closes
down in module protection status as if room temperature reaches the set value. And relevant error is
displayed. Compressor restores to run after stopping for 3 minutes.
If there are 6 continuous times of protection, compressor will stop and can not restart by itself. It
can only be restart by pressing "ON/OFF" button. In operation if operating time of compressor is
over 7 minutes, the number of times will be zero
6.1.3.7 overheating protection of module
When IPM temperature is too high, frequency of compressor will be demultiplied or limited. Wen
IPM temperature is beyond maximum, compressor closes down. The whole unit can only restart
when IPM temperature returns to norm and compressor has been stopping for 3 minutes.
If 3 times of IPM temperature protection happens in 1 hour, compressor will stop and can not
restart by itself. It can only be restart by pressing "ON/OFF" button
