The air conditioning system creates a humming sound and tries to start but cannot. The terminals are most likely to be the culprits if the ac compressor behaves in an erratic fashion.
To find out whether this is the issue, you can use a multimeter.
Rv ac compressor tries to start but won't. I still used rubber handled. A malfunctioning starting capacitor is likely to be the most common culprit. Thanks for the question good luck, robbie
⚡capacitors contain / store⚡ high voltage ⚡! It is defective if touching its wires to each other turns on the ac system. Turning the air conditioner on and off frequently may cause this problem.
With rv unplugged to ac power, short terminals with a rubber handled screw driver. I suggest you turn off the curcuit breaker in your control panel to the roof ac to prevent damage to the compressor and call a tech asap. If your ac isn’t getting the voltage it needs it won’t start.
When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, “uggg”…, for about 5 to 10 seconds and then all you hear is the. The causes of rv air conditioner compressor not coming on. The air conditioner is leaking

Replacing the blown fuse or fixing the tripped breaker will solve the problem.
The capacitor is the part that charges your air conditioner’s motor. The compressor tries to start (a 2 second hum) then stops. Remember to turn off the ac and shut off its power supply before testing your ac motor.
