what is a ac relay on a car ac relay switch turns the ac fan on and off depending on the temp of the freon too cold it turns off too warm it turns on depends on the preset temp
The temperature in the air gets cool enough, so its thermostat turns the AC off. When it warms enough, the thermostat turns it back on.
the laptop turns off when unplugged from AC adapter
it is supposed to, its an ac cutout switch that turns off ac compres to give you more power or acceleration. it can be bypassed
Your AC may make a loud noise when it turns off due to the sudden change in pressure within the system, causing components to vibrate or move. This noise is typically normal and not a cause for concern unless it is excessively loud or accompanied by other issues.
Check for loose connection or loose fuse in fuse panel
A simple answer would be; it turns on the ac compressor.
Yes, the bulb turns off at each zero-point crossing of the AC supply. Due to thermal mass/inertia, however, you won't see it because the temperature cannot follow the AC input frequency.
The computer turns the AC clutch off when accelerating for maximum engine power. The AC compressor uses up some engine horse power.
The ac system may be low on Freon. Check the pressure with a gauge. If the pressure is ok then check the ac relay, as they can be intermittent.
If you can smell AC gas in a building, it has a very strong odor, turn the AC off open all windows, and vent the building. It is extremely poisonous, get out of the building straight away. Call a AC contractor and they will find where it is leaking from and make repairs.
check the relay / check the temp sensor / try turning the fan on by turning on the AC - fan should come on when the AC compresor turns on /
