Compressor runs
1. Excessive air usage
continuously and / or
air output is lower
2. Clogged intake filter
than normal / low
discharge pressure
3. Open tank drain valve

tubing, etc.)
Worn out check valve
or in outside system)
Corrective Action
1. Make sure compressor is plugged in and switch is ON.
2. Check circuit breaker or fuse at electrical panel.
3. Release air from tank until compressor restarts
automatically.
4. Allow compressor to cool for approximately 30 minutes so
thermal overload switch will reset. Make sure compressor
is run in a clean, well-ventilated area where temperature
will not exceed 100°F.
5. Check all electrical connections.
6. Replace pressure switch.
7. Replace pump / motor assembly.
1. Disconnect other electrical appliances from circuit or
operate compressor on its own branch circuit.
2. Remove extension cord or refer to Extension Cord Chart on
page 5.
3. Replace check valve.
Do not disassemble check valve with
air pressure in tank; bleed tank.
4. Replace unloader valve.
5. Replace capacitor(s).
1. Check all connections with soap and water solution.
Tighten; or remove and apply pipe dope or pipe tape to
the threads, then reassemble.
2. Close tank drain valve.
3. Check tank for leaks with soap and water solution. If
leak is detected, tank must be replaced with genuine
replacement part.
4. Replace check valve.
1. Decrease air usage; compressor not large enough for air
requirement.
2. Clean or replace filter.
3. Close tank drain valve.
4. Check all connections with soap and water solution.
Tighten; or remove and apply pipe dope or pipe tape to
the threads, then reassemble.
5. Replace piston and cylinder.
6. Replace valve.
