Unstable air conditioner provides erratic cold air, the machine works but the room temperature is hot and cold at times.
Copper pipes, pipe connectors have a layer of white snow on the outside when you are using them air machine The temperature causes the air conditioner to show signs of leaking water and sticking to snow.

2.1. Check the electrical part of the block
Check block coil: Use a multimeter using an X1 or 10 Ohm scale to measure the resistance of each pair of block contacts. If the resistance readings of certain pairs are absent, they may have broken coils. If all pairs of contacts show resistance, the machine will still work normally.
Check block shell touch: Use a multimeter to measure the resistance at the machine’s contact pile with the outer shell. If any electrical terminal appears to have a resistance, the block will leak electricity. If the needle is not it should indicate that the coil is not leaking well.
Check winding insulation: Next check the compressor current. Plug in the power for the compressor to work and then use clamps to one of the 3 wires of the air conditioner compressor. If the current value of the wire is higher than the rated value, the block is damaged due to current eating. If the current is equal to the rated current written on the block, that’s fine. If the compressor is not working, it is damaged due to piston jam or broken coil.
