Table C-3:  R7184 Troubleshooting 

continued from previous page

 

Procedure Status 

Corrective 

Action 

Indicator light turns off. 

Eliminate external light source or permanently shield cad cell. 

4. Shield cad cell from 

external light. 

Indicator light stays on. 

4.  Replace cad cell with new cad cell and recheck. 
5.  If indicator light does not turn off, remove cad cell lead 

wires from R7184 and recheck. 

6.  If indicator light turns off, replace cad cell bracket 

assembly. 

7.  If indicator light does not turn off, replace controller. 

Burner starts. 

Trouble in thermostat or limit circuit. Check thermostat or limit 
wiring connections. 

5.  Jumper thermostat (T -T) 

terminals on R7184 

 

IMPORTANT 

First remove one thermostat 
lead wire. 

Burner does not start. 

Disconnect the line voltage power and open line switch. 
Check all wiring connections. 
Tighten any loose connections and recheck. 
If burner does not start, replace R7184 

 

Condition:  Burner starts then locks out on safety with indicator light flashing at 1 hz rate (½ second on, ½ second 
off) 

Indicator light stops flashing. 

Go to Step 7. 

6.  Reset oil primary control 

by pushing in and 
releasing red reset button. 

Indicator light continues to 
flash at 1 Hz rate. 

Verify that the control is not in restricted mode. (See notes at 
end of this table.). If not in restricted mode, replace R7184 

Ignition is off 

Spark ignitor could be defective. Check for line voltage at 
ignitor terminals. If line voltage is present, replace R7484. 

Ignition is on. 

Go to Step 8. 

7. Listen for spark after 

burner turns on (after 2 
second delay). 

Ignition is on but no oil is 
being sprayed into the 
combustion chamber. 

Wait for “Valve ON” delay to complete. Check oil supply, and 
oil line valve. Check for filter blockage or seized oil pump. 

Indicator light is on until the 
control locks out and starts 
flashing during lockout. 

Replace R7184 

8.  Check indicator light after 

flame is established, but 
before oil primary control 
locks out. 

Indicator light stays off. 

Go to step 9. 

Burner locks out. 

Go to step 10. 

9.  Check cad cell sighting for 

view of flame. 

• 

Disconnect line voltage 
power and open line 
switch. 

• 

Unplug cad cell and clean 
cad cell face with soft 
clothe. Check sighting for 
clear view of flame. 
Replace cad cell in socket. 

• 

Reconnect line voltage 
power and close line 
switch. 

• 

Start burner. 

Burner keeps running. 

System is OK.
