8Operating Instructionswww.chpower.comtroubleshooting ChartSymptom possible Cause(s) Corrective actionCompressor will notrun1. No electrical power 1. Plugged in? Switch on? Check fuse/breaker2. Breaker open 2. Reset, determine cause of problem3. Pressure switch bad 3. Replace4. Motor over worked 4. Turn off, let cool, turn on.5. Tank pressure above cut-in 5. Bleed tank pressure down to cut-in.Fuses blow / circuitbreaker tripsrepeatedly1. Incorrect size fuse, circuitoverloaded1. Check for proper fuse, use time-delay fuse. Disconnectother electrical appliances from circuit or operatecompressor on its own branch circuit.2. Extension cord usage - wronggauge wire and/or too long.2. Remove extension cord or refer to Extension Cord Chart onpage 4.3. Worn check valve 3. Replace check valve.Do not disassemble check valve withair pressure in tank; bleed tank.4. Defective unloader valve (onpressure switch)4. Replace unloader valve.5. Defective motor capacitor(s) 5. Replace capacitor(s)6. Defective motor 6. Replace motorTank pressure dropswhen compressorshuts off1. Loose connections (fittings,tubing, etc.)1. Check all connections with soap and water solution.Tighten; or remove and apply pipe dope or pipe tape tothe threads, then reassemble.2. Open tank drain valve 2. Close tank drain valve3. Tank leaks 3. Check tank for leaks with soap and water solution. Ifleak is detected, tank must be replaced with genuinereplacement part.Compressor runscontinuously and / orair output is lowerthan normal / lowdischarge pressure1. Excessive air usage 1. Decrease air usage; compressor not large enough for airrequirement2. Clogged intake filter 2. Clean or replace filter3. Open tank drain valve 3. Close tank drain valve4. Air leaks in piping (on machineor in outside system)4. Check all connections with soap and water solution.Tighten; or remove and apply pipe dope or pipe tape tothe threads, then reassemble.5. Piston ring worn 5. Replace piston and cylinder.6. Broken valve (in pump) 6. Replace valve7. Tank leaks 7. Check tank for leaks with soap and water solution. Ifleak is detected, tank must be replaced with genuinereplacement part.8. Defective pressure switch 8. Replace switchExcessive moisture indischarge air1. Excessive water in tank 1. Drain tank2. High humidity 2. Move to area of less humidity; use air line filter
