Frequently Asked Questions - AJEM12DWJ GE
How do I clean the filter on my GE AJEM12DWJ air conditioner?
Turn off and unplug the unit. Remove the front grille and slide out the filter. Wash the filter with warm water and mild detergent, then let it dry completely before reinstalling. It is recommended to clean the filter every 30 days during heavy use.
The remote control is not working. What should I do?
First, replace the batteries in the remote with new ones (typically AA or AAA). Ensure the remote sensor on the unit is not obstructed. If it still does not work, try resetting the unit by unplugging it for 5 minutes, then plugging it back in.
How do I install the GE AJEM12DWJ air conditioner in a window?
The unit is designed for double-hung windows. Open the window, place the unit on the sill, and extend the side panels to fill the gap. Secure the unit with the provided frame and brackets. Ensure the unit tilts slightly downward for proper condensate drainage.
What does the 'Energy Saver' mode do?
Energy Saver mode cycles the fan on and off with the compressor, rather than running continuously. This reduces energy consumption and helps maintain a more consistent temperature. The fan runs only when cooling is needed.
My air conditioner is leaking water indoors. What could be wrong?
Common causes include: the unit is not tilted slightly downward (it should tilt to the outside), the drain hole is clogged, or the unit is installed incorrectly. Check the installation manual and ensure the unit has a slight backward tilt. Clean any debris from the drain pan.
How do I set a timer on the GE AJEM12DWJ?
Use the remote control or the control panel to access the timer function. Typically, you can set a delay start or stop in 1-hour increments up to 24 hours. Refer to the user manual for exact button sequence.
What is the recommended room size for this air conditioner?
The GE AJEM12DWJ is suitable for rooms up to 550 square feet. For best performance, ensure the room is well-insulated and doors/windows are closed.
Can I use an extension cord with this air conditioner?
No, it is not recommended. Extension cords can cause voltage drop and overheating. Always plug the unit directly into a grounded 3-prong outlet.
How do I troubleshoot if the unit does not start?
Check that the unit is plugged in and the outlet is working. Ensure the circuit breaker has not tripped. Make sure the thermostat is set to a temperature lower than the room temperature. If still not starting, wait 3 minutes for the compressor delay protection to reset.
What type of refrigerant does this model use?
The GE AJEM12DWJ uses R410A refrigerant, which is environmentally friendly and ozone-safe. Any servicing involving refrigerant should be done by a certified technician.
