Remote control signals might not be received by your Mitsubishi Air Conditioner if the signal receiver is exposed to direct sunlight or very bright light. Try to block the sunlight or reduce the intensity of the light.
Why my Mitsubishi SRK25ZJ-S Air Conditioner does not work at all?
Your Mitsubishi Air Conditioner may not be working because the power switch is off, the timer is set in the “ON” position, or there is a power failure or a blown fuse. Check if the power switch is on, the timer setting, and the power supply.
What to do if my Mitsubishi Air Conditioner doesn't restart after a power cut?
If the auto restart function on your Mitsubishi Air Conditioner is not enabled, the unit will not restart automatically after a power cut. Use the remote control to start the operation again.
Why my Mitsubishi SRK25ZJ-S does not restart immediately?
If you have stopped your Mitsubishi Air Conditioner, please wait for three minutes before restarting. The microcomputer has a three-minute protection timer that automatically restarts it.
Why is airflow not blown out or not warm during heating with my Mitsubishi SRK25ZJ-S?
When outdoor temperature is low and humidity is high, your Mitsubishi Air Conditioner may automatically perform defrosting during heating operation. Please wait for the process to complete.
How to improve poor cooling or heating in my Mitsubishi SRK25ZJ-S?
Your Mitsubishi Air Conditioner may not be cooling or heating effectively because the thermostat is not set at a suitable temperature, the air filter is clogged, or doors or windows are open. Make sure the thermostat is set correctly, the air filter is clean, and all doors and windows are closed.
Why is there no airflow when starting the heating on my Mitsubishi SRK25ZJ-S Air Conditioner?
When starting the HEATING operation, airflow has stopped on your Mitsubishi Air Conditioner to prevent blowing out cold air until the indoor heat exchanger has warmed up. This usually takes about 2 to 5 minutes due to the HOT KEEP program.
Why is there no airflow when starting the DRY operation on my Mitsubishi SRK25ZJ-S?
When starting the DRY operation, the indoor fan on your Mitsubishi Air Conditioner may stop to prevent re-evaporation of dehumidified moisture and to save energy.
What causes poor cooling in my Mitsubishi SRK25ZJ-S?
Poor cooling on your Mitsubishi Air Conditioner can occur if there is direct sunlight entering the room, a heat source is present, or there are too many people in the room. Reduce these factors to improve cooling.
Why RUN light stays on even though operation was stopped on my Mitsubishi SRK25ZJ-S Air Conditioner?
The RUN light illuminates during CLEAN operation on your Mitsubishi Air Conditioner and turns off when CLEAN operation ends.
