1. Pressure switch connection
corroded
2. Starter is not getting enough
voltage to close coil
3. Low oil switch tripping
1. Replace pressure switch
2. Check unit voltage
3. Check the oil level in the unit
NOTE: Low Voltage-Low voltage can cause a multitude of problems. The most common cause of low volt-
age is when the wire size supplying the power to the compressor is too small. The longer the run of wire the
larger the diameter must be to overcome the inherent voltage loss caused by the wire resistance. The sup-
ply voltage at the main panel could also be low as supplied by you local power company or you may have
too many other pieces of equipment running off the same panel. You local electrician should be contacted
to evaluate and correct the problem according to the Nation Electric Code. Other Symptoms of low voltage
can be flickering lights and computer screen when the compressor tries to turn on.
You should always contact an authorized service center before attempting to fix or
repair your air compressor
Always make sure electrical power is off before removing any inspection covers or plates
