3. Make sure limit control is closed. 4. Check contacts between ignitor and the electrodes. 5. Check the oil pump pressure. R7184A,B,P,U INTERRUPTED ELECTRONIC OIL PRIMARY 3. On: cad cell is sensing flame. 4. Off: cad cell is not sensing flame. DELAY TIMES:...
Idle mode. 3. When flame or light is not present: a. R7184A,U (if valve-on delay is disabled) will apply power to the burner motor and ignitor. b. R7184B,P,U (if valve-on delay is enabled) will apply power to the burner motor and ignitor, enter/complete valve-on delay period and then apply power to the valve.
L1 of R7184.) IMPORTANT: First remove one thermostat lead. 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.
