NOTE: This section refers to Honeywell R7284 and R8184 series controls. The R7284G and
R8184G control use a LED light to display the troubleshooting status, and the R7284P
control comes with a display screen that will output the current operating state of the
burner or any troubleshooting errors that might arise in normal burner operation.
Troubleshooting tables on pages 10-11 are specific to burners that
come equipped with an oil primary control, and these sections only
apply if the general troubleshooting guide tells the licensed
contractor to consult these sections while servicing the burner.
