How to deal with peculiar smell in maintenance of Mianyang air conditioner?
?
The air conditioner has peculiar smell: the wind at the outlet of the air conditioner has a strong smell.
?
Cause analysis: This is because the condenser of your air conditioner indoor unit is too dirty to clean for a long time, which leads to mildew and odor. If you don't clean it in time, you may suffer from upper respiratory diseases.
?
Troubleshooting: This is easy to clean. Just go to the supermarket to buy disinfectant for air conditioning and spray it on the condenser of the indoor unit. You can immediately see black dirt coming out of the outside pipe. If the rest is clear, it's clean.

Air conditioning does not cool: the most common situation is not cooling in summer. The first thing to consider is whether the air conditioner will snow as long as there is no snow.

There are also some reasons that the air conditioner can't cool, for example, the air conditioning unit is too dirty to exchange heat and needs to be cleaned.
?
The installation gap of outdoor unit of air conditioner is too small to emit heat, so it is necessary to install diversion device for treatment.
?
Fault phenomenon: there will be a harsh sound after starting. When the machine is powered off, the indoor fan will rotate slowly.
?
Fault analysis: according to the phenomenon analysis, preliminarily determine the indoor motor power failure. Check the power supply voltage of the indoor fan. The voltage of the motor is 100V when it is stopped. After shutdown, the indoor motor is still running slowly and continuously. The heating of the indoor motor will cause the plastic motor frame to deform under heating, and the plastic sealed motor will move its position. This can cause the cross flow fan blades to collide with the chassis, emitting unpleasant noise and burning smell. Therefore, it was determined that the thyristor controlled by the fan was damaged.
?
Maintenance measures: replace the main control board.
