TROUBLE
POSSIBLE CAUSE
CORRECTIVE ACTION
Heater ignites but MAIN PCB
assembly shuts heater off after a
short period of time.
(Indicator Lamp is flickering and
room temp. display indicates “ E1 “)
1. Wrong pump pressure.
2. Dirty Air Output,Air Intake
or Lint Filter.
3. Dirty Fuel Filter.
4. Dirt in Nozzle.
5. Dirty Photocell Lens.
6. Photocell Assembly not
Properly installed.(Not seeing the
flame)
7. Bad electrical connection
between photocell and MAIN PCB
assembly.
8. Defective Photocell.
1. See Pump Pressure Adjustment,
Page 13.
2. See Air Output, Air intake
and Lint Filters, page 10.
3. See Fuel Filter, Page 13.
4. See Nozzle, Page 11.
5. Clean Photocell Lens, Page 12.
6. Make sure photocell boot is
properly seated in bracket,
Page 12.
7. Check electrical components
See wiring diagram, Page 16.
8. Replace Photocell, Page 12.
Heater will not ignite but motor
runs for a short period
of time.(Indicator Lamp 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 between
ignitor and MAIN PCB assembly.
8. Ignition wire is not attached to
spark plug.
1. Fill tank with kerosene.
2. See Pump Pressure Adjustment,
Page 13.
3. See Spark Plug, Page 12.
4. See Fuel Filter, Page 13.
5. See Nozzle, Page 11.
6. Flush fuel tank with clean
kerosene, Page 9.
7. Check electrical components
See wiring diagram, Page 16.
8. Attach ignition wire to spark plug.
See Spark Plug, Page 12.
Fan does not turn when heater is
plugged in and power switch was in
the “ ON “ Position.
(Indicator Lamp is on or flickering)
1. Thermostat setting is too low.
2. Bad electrical connection between
motor and MAIN PCB assembly.
1. Turn thermostat control knob to a
higher setting.
2. Check electrical connections, See
Wiring Diagram, Page 16.
(Indicator Lamp is flickering and
room temp. display indicates “E2”)
1. Sensor Failure.
1. Replace sensor.
See Wiring diagram, Page 16.
(Indicator Lamp is flickering and
room temp. display indicates “E3”)
1. Thermostat switch failure.
1. Replace switch.
See Wiring diagram, Page 16.
Heater will not turn-on
(Indicator Lamp is off)
1. Temperature limit safety device is
overheated.
2. No electrical power
3. Blown fuse.
4. Bad electrical connection between
temperature limit safety device and
PCB board.
1. Turn power switch to “OFF”
and allow to cool (about 10 min.)
2. Check to insure heater cord and
extension cord are plugged in.
Check power supply.
3. Replace safety fuse in PCB board.
4. Check electrical connections
See Wiring Diagram, Page 16.
NEVER LEAVE THE HEATER
UNATTENDED WHILE BURNING!
