If your Sakura Air Conditioner unit doesn't start, here are a few things to check: * If there was a power outage, press the ON/OFF button after power is restored. * Check for a blown fuse or tripped circuit breaker and replace the fuse or reset the breaker. * Make sure the power supply wiring phase is correct; if it's incorrect, modify the wiring phase.
Why does my Sakura SRT-30RA operate long or continuously?
Your Sakura Air Conditioner might run for extended periods or continuously due to several potential issues: * A low refrigerant charge: add refrigerant. * Control contacts fused: replace the control. * Air in the system: purge the system. * Defective insulation: replace or repair the insulation.
Why does my Sakura SRT-30RA compressor cycles on high pressure control?
If your Sakura Air Conditioner's compressor cycles on high pressure control, consider these possible causes: * High pressure control erratic in action: Check capillary tube for pinches and set control if required. * Compressor discharge valve partially closed: Open valve, or replace if defective. * Air in system: Purge the system. * Condenser fan not operating: Reset condenser fan overload. Check motor and wiring, repair or replace if defective.
What causes low airflow in my Sakura SRT-30RA?
Low airflow in your Sakura Air Conditioner can be caused by: * A filter filled with dust and dirt: Clean the filter. * Obstacles at the air inlet or outlet of the units: Remove any obstacles.
Why does my Sakura SRT-30RA compressor stop on low pressure control?
Your Sakura Air Conditioner's compressor may stop on low pressure control due to: * Low pressure control erratic in action: Raise differential setting. Check capillary for pinches. Replace control. * Compressor suction shutoff valve partially closed: Open valve. * Low refrigerant charge: Add refrigerant.
Why does my Sakura Air Conditioner compressor operates continuously?
If your Sakura Air Conditioner compressor runs continuously, check the following: * Dirty air filter: Clean the air filter. * Temperature setting too low (for cooling): Reset the temperature.
What causes a hot liquid line in my Sakura Air Conditioner?
A hot liquid line in your Sakura Air Conditioner could be due to a shortage of refrigerant caused by a leak. To resolve this, repair the leak and recharge the system.
What causes system noise in my Sakura Air Conditioner?
System noise in your Sakura Air Conditioner could be caused by: * Piping vibration: Support piping as required and check for loose pipe connections. * A noisy compressor: Check valve plates for valve noise, replace the compressor if there's a worn bearing, and check for loose compressor hold-down bolts.
What causes a frosted liquid line in my Sakura Air Conditioner?
A frosted liquid line in your Sakura Air Conditioner is often caused by a restricted filter dryer. Remove the restriction or replace the filter dryer.
What causes a frosted or swearing suction line in Sakura SRT-30RA Air Conditioner?
A frosted or sweating suction line in your Sakura Air Conditioner can be caused by a clogged capillary tube. Check the capillary tube.
