SOLUTIONS
- Make sure your battery is fully charged.
- If the battery's charge is not full, please
replace or re-charge your battery.
- Make sure thermostat is connected properly.
- If burner fan does not come on
when you turn thermostat dial, replace
thermostat.
- Make sure pressure switch is connected
properly to burner unit. Take cover off
pressure switch by unscrewing the 4 screws
on the front part of the switch (switch is
located on pump). Without touching the
contacts that conduct current, push on the
little button found on the micro switch
(button is located directly above the part that
attaches directly into pump).
- If burner comes on, replace pressure
switch.
- If burner does not come on, make sure
there is current going through switch
(consult a professional for this if you do
not know how to do this properly as
you can get severely injured by the
electrical current connected to your
machine). If current properly flows
through pressure switch to burner,
check ignitor.
- Please call a repair center for help to
conduct tests on the ignitor.
- If you see vapor coming out the
top of the coil when you try to turn
the burner on while the machine is
in use, fuel is passing through the
system properly but the ignitor is
unable to produce a spark.
Replace the ignitor.
- If you don't see vapor, check the
fuel line.
- Make sure you have enough fuel in the tank.
- If you have fuel, make sure the filter
and fuel line are not plugged or
damaged.
