TROUBLESHOOTING *Always be sure your heater is turned off, unplugged and cool to the touch before continuing
 with troubleshooting.

Is the indicator lamp on or flickering?
What error code is your heater displaying?
Does the heater ignite (flame present in combustion chamber) temporarily before cutting out?

  1. Check your power source. Be sure heater and extension cord are securely plugged in.
  2. You may have a blown fuse. Inspect and or replace fuse in PCB Assembly.
  3. Temperature Limit Switch may have tripped or complete Limit Switch failure. Switch unit to "OFF" and allow unit to cool for 10 minutes. Replace Limit Switch if needed (ORDER PARTS).
  4. Bad connection may exist between Temperature Limit Switch and PCB Assembly. Refer to WIRING DIAGRAM in TECHNICAL INFORMATION.
Room Temp Sensor (Thermistor) is disconnected or complete Sensor failure. Check Thermistor connection and replace if needed. Refer to WIRING DIAGRAM in TECHNICAL INFORMATION or ORDER PARTS.
  1. Confirm 125 PSI pressure using a pressure gauge inserted into rear pressure gauge port (top left corner of gear pump). After gauge is inserted the fan must be spinning to obtain reading. Turn adjusting screw (top right corner of gear pump) CLOCKWISE to increase & COUNTERCLOCKWISE to decrease pressure.
  2. If proper pressure cannot be achieved check Neck Filter, Pump Filter and Nozzle Filter for clogs or damage (refer to INSTRUCTION MANUAL in TECHNICAL INFORMATION) replace if needed (ORDER PARTS).
  3. Photocell is dirty or bad. Access and clean photocell lens using a DRY cloth or cotton swab (refer to INSTRUCTION MANUAL in TECHNICAL INFORMATION) replace if needed (ORDER PARTS).
  1. No fuel or fuel is contaminated. Drain and flush tank with fresh fuel if needed.
  2. Confirm 125 PSI pressure using a pressure gauge inserted into rear pressure gauge port(top left corner of gear pump). After gauge is inserted the fan must be spinning to obtain reading. Turn adjusting screw (top right corner of gear pump) CLOCKWISE to increase & COUNTERCLOCKWISE to decrease pressure.
  3. If proper pressure cannot be achieved check Neck Filter, Pump Filter and Nozzle Filter for clogs or damage(refer to INSTRUCTION MANUAL in TECHNICAL INFORMATION) replace if needed (ORDER PARTS).
  4. If correct pressure is confirmed, verify spark plug is arcing. Clean and re-gap electrodes to .14" (3.5 mm) if needed.
Thermostat Switch failure. Remove and Replace Main PCB Assy. Refer to INSTRUCTION MANUAL in TECHNICAL INFORMATION or ORDER PARTS
  1. Thermostat setting may be too low. Be sure it is set to a temp higher than the current room temp.
  2. Check electrical connection between Motor and PCB. Refer to WIRING DIAGRAM in TECHNICAL INFORMATION.
