Remedy
Check fuse or circuit breaker. Reset or replace as
necessary.
Disconnect all power to the controller. Disconnect
the wires from the controller. connect an ohmmeter
between the switch terminals. Lower the set point
of the controller, the switch should make. raise the
set point and re-check, switch should break. if the
controller operates improperly, replace it.
Refill the oil tank. A slight delay in the re-priming
of the fuel pump may cause the burner
programmer to require resetting before the boiler
operates satisfactorily.
Check fuse or Circuit breaker.
Reset or replace as required.
Check electrodes for carbvon build-up, clean if
required. Check settings adjust if required.
Check for cracks in porcelain, if found, replace.
Check for dirt on detector, clean as required.
Check for proper location of detector.
Check for faulty air switch by jumpering the two
air switch leads at the terminal block. If the boiler
starts and runs with the jumper in place, the air
switch should be replaced.
Check the level control relays are securly mounted
on their bases. Check the power supply to each.
The relays may be checked by swopping positions
and checking they are both functioning.
Check for clogged nozzle, clean or replace.
Check voltage between transformer neutral at
terminal block to be sure transformer is being
powered.
Check voltage between pilot terminal and neutral
and ignition terminal and neutral. Check must be
made before the control locks out on safety. If no
power replace control.
Disconnect all power to the controller. Disconnect
the wires from the controller. connect an
ohmmeter between the switch terminals. Lower
the set pointof the controller, the switch should
make. raise the set point and re-check, switch
should break. if the controller operates improperly,
replace it.
