Lets say you want to use a motor from a refrigerator and stick it on a lawnmower....Can you use that dimmer to control the speed ???
No, you cannot. Motor speed is determined by the 60 cycle frequency of the ac voltage. Dimmers control the voltage, not the frequency. Changing the voltage on the motor will not adjust the speed.
No. Refrigerator motors are a sorts that cannot be speed controlled at all. Never mind refrigerator motors are sealed in the compressor. You can use a typical lighting dimmer to control only universal AC/DC type motors, and at that not very powerful ones due to the power limit of the dimmer.
The air conditioner ought to have a 20 amp wall receptacle with the aid of itself circuit. Stabilizers won't help. If their is already a separate circuit for the A/C, there's an issue with the incoming skill traces on your place. additionally, lighting fixtures that are hooked as much as a dimmer change tend to dim / flicker extra from skill fluctuations.
