What causes abnormally high pressure in my mycom Air Compressor?
- A
  Aaron LewisAug 16, 2025
  Abnormally high pressure in your mycom Air Compressor can be caused by a heat exchange failure at the condenser (heat exchanger). Clean and wash the heat exchangers, using solvent depending on the contamination. Other causes include malfunction of the fan motor, thermo-switch, water spray bars, cooling water pumps, etc. (identify malfunctioning devices, examine their causes, take measures, and replace malfunctioning devices), a flow volume adjustment fault for cooling water, brine, etc. (readjust manually or examine the cause and take measures if an automatic control valve is used), or poor performance in the heat exchanger (re-examine the conditions to improve if the trouble is caused by a change in operating conditions).

What to do if my mycom Air Compressor stops immediately after startup?
- T
  Tyler ArcherSep 12, 2025
  If your mycom Air Compressor stops immediately after startup, it could be due to the low pressure protection circuit being activated. Check for and stop any refrigerant leaks, then replenish the refrigerant, being aware of potential moisture contamination in the system. Another cause might be insufficient refrigerant circulation volume; if there are any heat exchange failures, such as poor defrost performance, investigate the cause and take corrective actions. A malfunction of the low pressure protection device, pressure sensor, relays, etc., could also be the reason. In this case, identify the malfunctioning devices, examine their causes, take appropriate measures, and then replace the faulty devices.

What causes faulty indication of capacity control position in my mycom 220JS-V?
- L
  Linda JamesAug 31, 2025
  Faulty indication of capacity control position in your mycom Air Compressor may arise from imprecision in the compressor indicator. Manually tighten screws to the 0% indication position of compressor capacity control. It could also be due to imprecision in the controller capacity control indicator, in which case, replace the indicator cam. Another potential cause is a malfunction in the potentiometer; if this is caused by aging degradation or prolonged partial load operation, replace the potentiometer.

What causes capacity control malfunction in my mycom 220JS-V Air Compressor?
- D
  Daniel MedinaSep 4, 2025
  Capacity control malfunction in your mycom Air Compressor can occur if 100% or 0% is undetected by the indicator; replace the micro-switch in this case. Malfunction of solenoid (modular) valves or related relays for capacity control can also cause this issue; for aging degradation, replace the parts. Internal leakage of solenoid (modular) valves for capacity control is another possibility; if caused by prolonged low load operation, improve by re-examining the operation method.

How to address abnormal vibration and/or noise in my mycom Air Compressor?
- D
  Donna NelsonSep 7, 2025
  Abnormal vibration or noise in your mycom Air Compressor might be due to insufficient axis adjustment with the motor side; readjust the shaft-center. Another cause could be a large runout in the Male rotor axis; if loose locknuts exist and no other fault is found in parts such as the thrust bearing, tighten the locknuts evenly. Damage to the thrust bearing can also result in abnormal vibration or noise. Note that the appropriate time for replacement will differ due to operating conditions.
