PROBLEM POSSIBLE CAUSE POSSIBLE ACTION(S)
Pump will not prime and Pump motor is
NOT running.
1. There is NO power on the
pump circuit from the burner.
2. The pump motor has shut off
on thermal overload.
1. Start the burner and adjust the air
pressure regulator to 15 PSI. (a)
Refer to the wiring diagram and
ladder schematic in Appendix B to
troubleshoot the pump circuit from the
burner to the pump. (b) With the
burner running, check for power at the
wires on the air pressure switch. If
there is NO power at the air pressure
switch, replace the burner motor. If
there is power at the air pressure
switch, replace the air pressure
switch.
2. (a) The pump motor is too hot—the
internal thermal protection switch shut
the motor off. Wait for the motor to
cool down; the thermal switch will
automatically reset. Check voltage
and amperage draw of the pump
motor. Call your dealer if the problem
persists. (b) The coupling is not
adjusted properly, keeping the shafts
of the motor and pump from turning
freely. Re-position the coupling so
that both shafts turn freely. (c) The
shaft on the motor or oil pump will not
turn freely. If you can’t turn the
shafts, replace the faulty part(s).
Fan motor runs all the time
1. Fan motor circuit is wired
incorrectly.
1. Refer to wi
ing diagram and ladder
schematic in Appendix B to
troubleshoot the fan motor circuit.
Fan motor will not run. 1. The fan
motor is not wired
correctly.
2. The Blower / Fan switch is
defective.
3. The fan motor has overheated
and shut down on thermal
reset.
1. Check the fan motor wiring. Refer to
the wiring diagram and ladder
schematic in Appendix B. Follow the
directions in Section 6 to test for
proper fan operation. If the fan does
not operate, shut OFF power to the
furnace and call your Clean Burn
dealer for service.
2. Replace the Blower / Fan switch.
3. The fan motor is too hot – the internal
thermal protection switch shut the
motor off. Wait for the motor to cool
down; the thermal switch will
automatically reset. Check voltage
and amperage draw of the fan motor.
Call your dealer if the problem
persists.
