How to improve poor heating performance of Kaisai Air Conditioner?
- J
  Justin AndersonAug 3, 2025
  If your Kaisai Air Conditioner isn't heating well, it could be due to a few reasons. If the outdoor temperature is lower than 7°C (44.5°F), the unit's heating performance may be reduced. Cold air entering through doors and windows can also impact heating, so make sure that all doors and windows are closed during use. Low refrigerant levels due to leaks or long-term use can also cause poor heating; in this case, check for leaks, re-seal if necessary, and top off the refrigerant.

  If your Kaisai Air Conditioner isn't working, there could be several reasons. It might be due to a power failure, so wait for the power to be restored. Check if the power switch is turned on. A burned-out fuse could also be the culprit, in which case you should replace it. Dead batteries in the remote control can also prevent the unit from starting, so replace them. Finally, the unit’s 3-minute protection might be activated; wait three minutes after restarting the unit.

  If your Kaisai Air Conditioner starts and stops frequently, there could be a few reasons. There might be too much or too little refrigerant in the system, so check for leaks and recharge the system with refrigerant. Air, incompressible gas, or foreign material in the refrigeration system can also cause this issue, so evacuate and recharge the system with refrigerant. A blocked system circuit can lead to frequent cycling; determine which circuit is blocked and replace the malfunctioning piece of equipment. The compressor might be broken, requiring replacement. Finally, voltage that is too high or too low can cause this issue, so install a manostat to regulate the voltage.

Why is my Kaisai RG57A7/BGEF cooling poorly?
- L
  Lauren TaylorNov 16, 2025
  If your Kaisai Air Conditioner isn't cooling effectively, several factors could be responsible. The temperature setting might be higher than the room temperature, so lower it. A dirty heat exchanger on either the indoor or outdoor unit can reduce cooling efficiency; clean the heat exchanger. Also, a dirty air filter restricts airflow, so remove and clean the filter. Obstructions blocking the air inlet or outlet of either unit will impact performance, so turn the unit off, remove any obstructions, and turn it back on. Open doors and windows let warm air in, so ensure they are closed. Excessive heat from sunlight can also overwhelm the unit, so close windows and curtains. Finally, low refrigerant levels due to leaks or long-term use can cause poor cooling; check for leaks, re-seal if necessa...
