20TROUBLESHOOTINGSymptom Possible (Cause(s)) Corrective ActionHeater ignites but MAIN PCBassembly shuts heater off after ashort period of time. (IndicatorLamp is flckering and room temp.display indicates “E1”1. Wrong pump pressure2. Dirty air output, air Intake or lint lilter3. Dirty fuel filter4. Dirt in nozzle5. Dirty photocell lens6. Photocell assembly not properly Installed (notseeing the flame)7. Bad electrical connection between photocelland MAIN PCB assembly.8. Defective photocell9. Cracks in end filter cover.10. Defective rotor& vane.11. Splits/cracks on air line.12. Air leaks around the pump area.1. See Pump Pressure Adjustment, page 162. See Air Output, Air Intake and Lint Filters, page 133. See Fuel Filter, page 164. See Nozzle, page 145. Clean Photocell Lens, page 156. Make sure photocell boot is properly seated inbracket, Page 157. Check electrical components. See Wiring Diagrams,page 188. Replace Photocell, page 159. Check for cracks in end filter cover.Replace if cracked,page 1310. Check rotor & vane condition.Replace if chipped,cracked,page 1211. Check air line for splits/cracks.Replace if splited,cracked,page 1312. Check air leaks around the pump area,page 13Heater will not ignite but motor runsfor a short period of time. (IndicatorLamp is flickering and room temp.display indicates “ E1 “)1. No fuel in tank.2. Wrong pump pressure.3. Carbon deposits on spark plug and/or improper gap.4. Dirty fuel filter.5. Dirt in Nozzle.6. Water in fuel tank.7. Bad electrical connection betweenignitor and MAIN PCB assembly.8. Ignition wire is not attached to spark plug.1. Fill tank with kerosene.2. See Pump Pressure Adjustment, Page 16.3. See Spark Plug, Page 15.4. See Fuel Filter, Page 16.5. See Nozzle, Page 146. Flush fuel tank with clean kerosene, Page 12.7. Check electrical components See wiring diagram,Page 18.8. Attach ignitor to spark plug. See Spark Plug, Page 15.Fan does not turn when heater isplugged in and power switch was inthe “ ON “ Position.(Indicator Lamp is on or flickering)1. Thermostat setting is too low.2. Bad electrical connection betweenmotor and MAIN PCB assembly.3. Jammed/Rotor1. Turn thermostat control knob to a higher setting.2. Check electrical connections, See Wiring Diagram, Page 18.3. Remove pump cover & Replace rotor, ETC.(Indicator Lamp is flickering androom temp. display indicates “E2”)(Indicator Lamp is flickering androom temp. display indicates “E3”)1. Sensor Failure. 1. Replace sensor. See Wiring diagram, Page 18.Heater will not turn-on (IndicatorLamp is off)1. Thermostat switch failure2. Temperature limit safety device is overheated3. No electrical power4. Blown fuse5. Bad electrical connection between temperaturelimit safety device and PCB board1. Replace MAIN PCB2. Turn power switch to “OFF” and allow to cool (about 10 min.)3. Check to insure heater cord and extension cord areplugged in. Check power supply4. Replace safety fuse in PCB board. See ReplacingFuse, page 175. Check electrical connections.
