There is a blue light flashing in the hotel vent.

There is a blue light flashing in the hotel vent, which may be a normal light or a micro-switch problem in the hotel.

If it is a normal light, the blue light may blink as follows:

1. Fire warning: The hotel may be supervised by the fire department, so it needs to turn on the blue flashing light for early warning.

2. Energy-saving lamps: In order to save electricity, some hotels use blue energy-saving lamps for lighting.

3. Blue air conditioning indicator light: In order to facilitate customers to confirm whether the air conditioner is turned on or remind the current temperature, a blue indicator light will be set near the air conditioning port.

If the blue light flashes because of the microswitch in the hotel, I suggest you check the microswitch in the hotel to ensure that the switch works normally.

The above are some possible reasons for the blue light flashing in the hotel vents, and the specific reasons need to be judged according to the actual situation of the hotel. If the problem still exists or requires more specific answers, please consult the relevant personnel.
