  Your Senville Air Conditioner might not be working due to several reasons. First, check for a power failure and wait for the power to be restored. Ensure that the power is turned on. If the fuse is burned out, replace it. If the remote control batteries are dead, replace them. Also, the unit’s 3-minute protection might be activated; wait three minutes after restarting the unit. Finally, check if the timer is activated and turn it off if necessary.

  If your Senville Air Conditioner is emitting a bad odor, it could be due to a couple of reasons. The unit may have absorbed odors from the environment, such as furniture, cooking, or cigarettes, which are then emitted during operation. Alternatively, the unit’s filters may have become moldy and should be cleaned.

Why does my Senville Air Conditioner start and stop frequently?
- A
  Adam HawkinsAug 25, 2025
  The frequent starting and stopping of your Senville Air Conditioner can be attributed to several issues. There might be too much or too little refrigerant in the system, so check for leaks and recharge the system with refrigerant. Another cause could be incompressible gas or moisture in the system, requiring you to evacuate and recharge the system with refrigerant. A broken compressor could also be the reason, in which case you would need to replace it. Lastly, the voltage might be too high or too low, and you may need to install a manostat to regulate the voltage.

Why is my Senville SENL/09CD/220/IX Air Conditioner not cooling properly?
- J
  Jordan MckenzieNov 18, 2025
  Several factors can cause poor cooling performance in your Senville Air Conditioner. Ensure that the temperature setting is not higher than the ambient room temperature. A dirty heat exchanger on either the indoor or outdoor unit can also be the culprit; clean the affected heat exchanger. Similarly, a dirty air filter should be removed and cleaned. Check for any blockages in the air inlet or outlet of either unit, and remove any obstructions. Make sure all doors and windows are closed to prevent warm air from entering. Close windows and curtains to reduce excessive heat from sunlight. Reduce the number of heat sources in the room, such as computers and electronics. If there's low refrigerant due to a leak or long-term use, check for leaks, reseal if necessary, and top off the refrigerant. ...
