TROUBLESHOOTING
8. TROUBLESHOOTING
A. GENERAL
The following table shows conditions that may possibly occur with the Pinnacle Oil Boiler and instructions on how to
troubleshoot these conditions.
Condition
The boiler does not run and the
control screen is blank.
The boiler does not run and the
control screen is on.
The burner starts, and then locks
out on safety with indicator light
flashing.

1. Make sure that 120 VAC power is present at Terminals L & N in the control panel.
2. Make sure the boiler service switch is switched on.
1. Check if the "Dem" segment is visible on the control display. This indicates that the
control is getting a demand from either the thermostat or the DHW tank.
2. Check for the burner symbol on the control display. This symbol indicates that the
temperature control is calling for the burner to operate.
3. Check indicator light on the Burner Primary control.
a. If it is on, it is detecting light, connections are shorted or the cad cell or control is
defective. Shield cad cell from light source.
i. If the indicator light goes off, eliminate the external light source or permanently
shield the cad cell.
ii. If the indicator light stays on, replace cad cell. If indicator light does not turn off,
remove cad cell lead wires. If light goes off replace cad cell bracket assembly. If
indicator light does not turn off, replace controller.
b. If it is off, jumper the limit terminal and L1.
i. If the burner starts, check the limit circuit (See Step 4).
ii. If the burner doesn't start, disconnect line voltage power by turning off the
service switch. Check all wiring connections. Tighten any loose connections and
recheck. If burner still doesn't start, replace the primary control
4. Check the boiler water temperature gauge. If the boiler water is above 210°F check
boiler circulator operation. Be sure that all air is purged from the system.
5. Depress the vent temperature limit reset button. Check all wiring in the limit circuit.
1. Check that limit switches are closed and contacts are clean.
2. Check for line voltage power at the oil primary control. Voltage should be 110 VAC to
130 VAC.
3. Reset primary control by pushing in and releasing the red reset button.
a. If the indicator light stops flashing go to step (4).
b. If the indicator light continues to flash, verify that the primary control is not in
restricted mode. If not in restricted mode, replace primary control.
4. Burner will re-try for ignition. Listen for spark after burner turns on (after 2 second
delay).
a. If there is no spark, check for line voltage at the igniter terminals, if line voltage is
present, replace the igniter.
b. If there is a spark, check to see if oil is being sprayed into the combustion chamber.
If there is no oil, check oil valve, oil valve wiring, pump and oil supply.
5. Check indicator light after the flame is established but before the oil primary control
locks out.
a. If the indicator light is on until the control locks out and starts flashing during
lockout, replace the primary control.
b. If the indicator light stays off, go to step (6).
