How many volts should an AC compressor get?
Central air conditioners require a 220-volt or 240-volt, dedicated circuit for operation. When a central air conditioner starts up, it may require up to 5,000 watts of electricity, making it one of the largest consumers of electric power in the home.
How many volts is a car AC compressor?
The AC clutch of most cars operates on 12 volts (all the ones I have worked on at least) so if you are only getting 2.7 volts it simply is not going to engage. Check the operation of the clutch and AC system quickly by running a temporary jumper wire from the battery to the clucth.
What should the ground voltage be on a Jetta?
The powertrain control module (PCM) will ground this reference to request a compressor shutdown for a wide open throttle (WOT) condition or lack of throttle basic setting. Eleven volts is the normal expected reading at this pin. 4. Verify 12 volts to pin T14/4 (red/gray) via fuse 16, at all times. 5. Verify good ground to pin T14/6 (brown/black).
Why is the AC clutch on my Jetta not working?
Make and Model > Volkswagon > Jetta > VW Jetta AC Compressor… Shops are finding the root problem for a VW Jetta compressor clutch won’t engage may be caused by a fuse box corrosion issue, not a bad compressor clutch or low refrigerant issues as most people suspect (VW calls this a fuse bracket).
What’s the duty cycle on a Volkswagen a / C compressor?
3. Verify an approximate 70% duty cycle from the A/C pressure sensor at pin T14/2 (white) with the ignition on and the compressor not running (duty cycle will decrease as the high-side pressure increases).
What does variable voltage mean on a compressor?
If the variable voltage signal to the compressor is close to 0V, or 10% on time, then something is commanding the system off. Check the voltage signal at the pulse-width modulated compressor solenoid control wire at the a/c control module first.
