The main circuit board supplies ac power to the ignitor ( black transformer looking device) and the transformer increases the voltage that is supplied to the sparking device. Make sure the wires are connected to the sparking device and the ends of this device are approximately 3mm apart and that it is in the general position near the end of the nozzle. If you do not hear a "clicking" sound it could be the main board, wires or sparking device.

There is a flame sensor inside the burner unit. The sensor is like a photo cell that must see the light of the flame or it will tell the burner control to stop the power. You need to see if there is a soot film on the lense of the sensor and make sure the sensor is aimed straight. If the sensor is clean and aimed straight (and the problem persists) then there may be a clogged nozzle that is giving a poor flame and the sensor does not see a good flame therefore shuts down the unit. If the nozzle is at fault, then you for sure need to replace the oil filter. New nozzles are $4-8 and the size & spray angle is stamped on the nozzle. If there is still a problem, then you need to see if the pump is giving approx. 100psi pressure, then finally (the last step) would be to replace the burner control $60. Goodluck< Macgivor

First thing is to download the service manual.

You need to make sure the filters are clean and that you are getting the proper air pump pressure.

If the units starts up and runs good and slowly goes out it will normally be due to a lack of fuel getting to the nozzle. When there is not enough fuel being delivered to the nozzle from either a clogged fuel filter of dirty air pump output filter the unit will slowly shut down from lack of fuel.

If the unit shuts down while it is running properly and the nose come is orange then you probably have a problem with a photocell or the flame out control.

If you have other questions you can contact our service department at 269-685-4125 at extension 224
