Quite simple, its overheating, check oil level, clean/blow out cooler, check/replace thermo valve.
Make sure fan is spinning.
Do all above, if no change then post a reply to this message

if your compressor overheats within seconds of starting, your problem is oil stop valve

if it takes a few minutes or longer to over heat it is likely low on oil, coolers are plugged, or your thermostat valve is sticking

to determine if thermostat valve is working, feel the fittings leading into and out of the oil cooler when unit is running hot, both should feel hot, if one feels close to ambient temp your thermostat valve needs to be replaced or bypassed

Element outlet alarm could be oil leakages leading to low oil level and consequently leading to high temperatures. Leakages have to be fixed.

Good day sir pls I need your help for GA 37 hold modern if compressor have overheating pls what is the actually problem coming from sir

Is the oil cooler getting hot? Then is the line from the bypass valve getting warm? If not, might be the bypass is stuck in bypass.
If that’s OK, make sure the scavenge line is clear.

Renew oil filter clockwise to loosen , Remove oil vessel cover renew filter inside, change oil and clean the oil cooler… not sure if air cooled GA-37 has thermo valve

Will alread change everything both oil cooler wash an overhaul element
