How do I know if my vacuum motor is bad?

If the motor still has some life in it, it will start, but if it is going bad, it will only work for 10-15 minutes or less. If it doesn't start at all, it is obviously bad. Sometimes slapping the motor or vacuum unit will jar the motor and get it to work again for a few minutes. Intermittent motors should be replaced.

What affects suction pressure?

Overcharging leads to overfeeding the evaporator with refrigerant, which leads to higher suction pressure. Another possibility is having oversized EXV causes an overfeed to the evaporate, which increases your suction pressure.
