Problem
Possible Cause
Solution
Heater fires, but Main PCB shuts
heater off after a short period of time.
Lamp is flickering, and LED display
shows “E1”.
1. Incorrect pump pressure
2. Dirty Input, Output or Lint Filter
3. Dirty Fuel Filter
4. Nozzle is Dirty
5. Photocell lens is Dirty
6. Photocell not installed properly
7. Photocell Defective
8. Improper electrical connection between
Main PCB and Photocell.
1. Adjust Pump Pressure (Page 11)
2. Clean/replace Air Filter (Page 9)
3. Clean/replace Fuel Filter (Page 10)
4. Clean/replace Nozzle (Page 9)
5. Clean/replace Photocell (Page 10)
6. Adjust Photocell position (Page 10)
7. Replace Photocell (Page 10)
8. Check wiring connections (See Wiring
Diagrams, Page 14)
Heater will not operate, or motor runs
for short time. Lamp flickers and LED
display shows “E1”.
1. No kerosene in fuel tank
2. Incorrect pump pressure
3. Corroded Spark Plug or incorrect plug
gap.
4. Dirty Fuel Filter
5. Dirty Nozzle
6. Moisture in Fuel/Fuel Tank
7. Improper electrical connection between
Transformer and Circuit Board
8. Ignitor Wire not connected to Spark
Plug
9. Defective Ignitor
1. Fill tank with fresh kerosene
2. Adjust Pump Pressure (Page 11)
3. Clean/replace Spark Plug (Page 10)
4. Clean/replace Fuel Filter (Page 10)
5. Clean/replace Nozzle (Page 9)
6. Rinse out fuel tank with clean fresh
kerosene (Page 9)
7. Inspect all electrical connections. See
Wiring Diagrams (Page 14)
8. Re-attach Ignitor wire to Spark Plug
(Page 9)
9. Replace Ignitor
Fan does not operate when heater is
plugged in and Power Switch is in the
“ON” position. The lamp is flickering or
on and LED Display shows “E1” or
“E2”.
1. Thermostat is set too low (Does not
apply to HS-45-KFA)
2. Broken electrical connection between
Main PCB and motor
1. Rotate thermostat to a higher setting
2. Inspect all electrical connections. See
Wiring Diagrams (Page 14)
Lamp is flickering, and LED display
shows “E3”
1. Thermostat Switch has failed
1. Replace Thermostat Switch. Wiring
Diagrams (Page 14
)
Poor Combustion and / or excess soot
production
1. Flames extending beyond heater
2. Low heat output
3. Poor quality of fuel
4. Improper Maintenance
1. Decrease Pump Pressure (Page 11)
2. Increase Pump Pressure (Page 11)
3. Be sure fuel is not contaminated or old
4. Use proper maintenance (Pages 9-11)
Heater does not turn on and the lamp
is not lit
1. Temperature limit sensor has overheat-
ed
2. No electrical power
3. Fuse Blown
4. Improper electrical connection between
Temperature Limit Sensor and Circuit
Board
1. Push Power Switch to “OFF” and allow
heater to cool for 10 minutes. Push
Power Switch to back to “ON”
2. Check power cord and extension cord
to insure of proper connection. Test
power supply
3. Check/replace Fuse
4. Inspect all electrical connections. Wiring
Diagrams (Page 14)
