Issue Troubleshooting Solution
What is 3-Minute Compressor Protection?
All TOSOT Air Conditioners have a 3-Minute Compressor Protection feature to help extend
the lifespan of your unit. You may notice this happening when the unit is not blowing cold air
or you can’t hear the sound of the compressor. Below are some situations where the 3-Minute
Protection Mode will be activated:
A. Your unit just experienced a power outage. The compressor will restart again after 3 minutes.
B. After you switch from the fan or dry mode to the cooling mode, there is a 3-minute delay
before the compressor starts up.
C. If the unit is powered on, then powered off, then powered on again within a 3-minute period,
there will be a 3-minute delay before the compressor starts again.
D. If the ambient room temperature is lower than the set temperature on your control panel,
the compressor will power off for 3 minutes and restart once the ambient room temperature
rises above the set temperature again.
