— — 2. Check for line voltage power at the oil primary control. Voltage should be 120 Vac. — — 3. Check indicator light with burner off, no call for heat (no flame). Indicator light is on. Cad cell or controller is defective, sees external light or connections are shorted. Go to step 4. Indicator light is off. Go to step 5. 69-1233—2 6 R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY 4. Shield cad cell from external light. Indicator light turns off. Eliminate external light source or permanently shield cad cell. Indicator light stays on. • Replace cad cell with new cad cell and recheck. • If indicator light does not turn off, remove cad cell leadwires from R7184 and recheck. • If indicator light turns off, replace cad cell bracket assembly. Refer to TRADELINE® Catalog for bracket part numbers. • If indicator light does not turn off, replace controller. 5. On warm air systems, jumper thermostat (T to T) terminals on R7184. (On hydronic systems jumper Limit terminal and L1 of R7184.) IMPORTANT: First remove one thermostat lead. Burner starts. Trouble in thermostat or limit circuit. Check thermostat or limit wiring connections. Burner does not start. • Disconnect 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 (1/2 second on, 1/2 second off). 1. Check that limit switches are closed and contacts are clean. – – 2.

Indicator light stops flashing. Go to step 7. Indicator light continues to flash at 1 Hz ratea . Verify that control is not in restricted mode (see footnote a). If not in restricted mode, replace R7184. Procedure Status Corrective Actions 7 69-1233—2 R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY Procedure Status Corrective Actions 7. Listen for spark after burner turns on (after a 2 second delay. Ignition is off. Spark ignitor could be defective. Check for line voltage at ignitor terminals. If line voltage is present, replace R7184. Ignition is on. Go to step 8. Ignition is on, but no Wait for Valve On Delay to complete (R7184B,P, and oil is being sprayed U). Check oil valve, oil valve wiring, pump and oil into the combustion supply. chamber. 8. Check indicator light after flame is established, but before oil primary control locks out. Indicator light is on until the control locks out and starts flashing during lockout. Replace R7184. Indicator light stays off. Go to step 9. 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 cloth. Check sighting for clear view of flame. Place cad cell back in socket. • Reconnect line voltage power and close line switch. • Start burner. Burner locks out. Go to step 10. Burner keeps running. System is okay. 10. Check cad cell. • Disconnect line voltage power and open line switch. • Remove existing cad cell and replace with new cad cell. • Disconnect all wires from thermostat terminals to be sure there is no call for heat. • Reconnect line voltage power and close line switch. • Expose new cad cell to bright light, such as a flashlight. Indicator light is on. Place control back on burner. Go to step 6. Indicator light is off. Go to step 11. 11. Check cad cell bracket assembly. • Disconnect line voltage power and open line switch...
