Why does my mycom 3225**C stop immediately after startup?
- M
  Mrs. Donna Hood MDAug 18, 2025
  If your mycom Compressor stops immediately after starting, it could be due to insufficient refrigerant flow (check for leaks, stop them, and add refrigerant) or insufficient liquid supply (inspect the expansion valve and liquid supply strainer). Another cause could be heat exchange failure in the heat exchanger, so investigate the cause and take necessary actions. Lastly, the failure of a low pressure protection device, pressure sensor, or relay could be the reason, so identify and replace any defective devices.

How to troubleshoot a mycom 3225**C Compressor that does not start up?
- W

  If the mycom Compressor does not start, several factors could be at play. It might be due to the power source being off, so you should use a check sheet for post-inspection actions. The main motor could have failed, so refer to the motor's operation manual for troubleshooting. The micro-switch might not be sensing capacity control, in which case you should replace it. Other potential causes include a defective capacity control oil supply line (readjust), leaks or clogs in piping or the solenoid valve (remove cause and check/replace oil), or a clogged pressure pipe (remove clogging and check/replace oil). Also check for oil pressure, cooling water circulation, clogs in the circulation route (remove the clogging), or issues with the compressor startup circuit (replace faulty components). Fin...

What to do if the mycom 3225**C Compressor has low oil pressure?

  Bruce DaviesNov 9, 2025
  If your mycom Compressor's oil pressure is low, it could be due to several reasons. The oil filter element might be clogged, so remove the clogging and check/replace the oil. There may be internal defects, so check for oil contamination and conduct vibration/noise diagnosis, overhauling the compressor if necessary. Other possible causes include insufficient oil in the oil separator (inspect the oil heater and relays), insufficient oil return due to refrigerant circulation issues (correct refrigerant circulation and return oil from the load-side heat exchanger), or clogs in the oil return passage (remove the causes and restore the system). Also, check for extensive oil leaks and address them and ensure the oil pressure detection function is working correctly by identifying and replacing any...

What causes unusually high pressure in a mycom 3225**C Compressor?
- A
  anthonyjohnsonNov 25, 2025
  If the pressure in your mycom Compressor is unusually high, it could stem from several issues. Heat exchange failure in the condenser might be the cause, so clean and wash it, possibly using chemical cleaning. Another potential cause is failure in the fan motor, thermo switch, water spraying pipes, or cooling water pumps, so identify and replace any defective devices. Faulty adjustment of cooling water or brine could also be to blame, so readjust the valve or investigate the cause if using an automatic control valve. Other causes of insufficient cooling water flow should be investigated, such as clogged filters, leaks in circulation routes, or frozen water supply routes. Deficiency in heat exchanger performance may also be a factor, so re-examine operating conditions or improve the install...
