TROUBLE
POSSIBLE CAUSE
CORRECTIVE ACTION
Heater ignites but main PCB assem-

period of time (Indicator Lamp is
flickering and temperature display
indicates "E1").
"
Wrong pump pressure
See pump pressure ad-
justment
Dirty air output, air intake
of lint filter.
See air output, air intake
and lint filters
Dirty fuel filter
See fuel filter
Dirt in nozzle
See nozzle
Dirty photocell lens
Clean photocell lens
Photocell assembly not
properly installed (not see-
ing the flame)
Make sure photocell
boot is properly seated in
bracket
Bad electrical connection
between photocell and
main PCB assembly
Check electrical com-
ponents. See wiring
diagram
Defective photocell
Replace photocell.
Heater will not ignite but motor
runs for a short period of time
(Indicator lamp is flickering and
temperature display indicates "E1"
No fuel in tank
Fill tank with kerosone
Wrong pump pressure
See pump pressure ad-
justment
Carbon deposits on spark
plug and/or improper gap
See spark plug
Dirty fuel filter
See fuel filter
Dirt in nozzle
See nozzle
Water in fuel tank
Flush fuel tank with clean
kerosone
Bad electrical connection
between ignitor and main
PCB assembly
Check electrical com-
ponents. See wiring
diagram
Ignitor wire is not attached
to spark plug
Attach ignitor to spark
plug
Fan does not turn when heater is
plugged in and power switch was in
the "On" position. (Indicator lamp
is on or flickering)
Thermostat setting is too
low
Turn thermostat control
knob to a higher setting
Bad electrical connection
between motor and main
PCB assembly
Check electrical connecti-
ons. See wiring diagram
Indicator lamp is flickering and tem-
perature display indicates "E2"
Temperature sensor dis-
connected
Reconnect sensor. See
wiring diagram
Sensor failure
Replace sensor. See wi-
ring diagram.
Indicator lamp is flickering and tem-
perature display indicates "E3"
Thermostat switch failure
Replace switch. See wi-
ring diagram
Heater will not turn on (Indicator
lamp is off)
Temperature limit safety
device is overheated
Turn power swith to
"Off" and allow to cool
(about 10 minutes)
No electrical power
Check to insure heater
cord and extension cord
are plugged in. Check
power supply
Blown fuse
Replace safety fuse in
PCB board
Bad electrical connection
between temperature
limit safety device and PCB
board
Check electrical connecti-
ons. See wiring diagram
