Troubleshooting

The RM7897A flame safeguard is equipped with an LED to aid in the diagnosis of burner operation and problems. Fault

identification is a series of fast- and slow-blinking LED lights. The fast blinks identify the tens portion of the fault code (two fast

blinks is 20), while the slow blinks identify the units portion of the fault code (two slow blinks is 2) . Two fast blinks followed by two

slow blinks would be fault code 2-2. This identifies a flame signal absent at the end of the pilot flame establishing period. (See

Table 7: Fault codes

for Blinking Fault Code List .) The LED code repeats as long as the fault exists . To clear the fault, press the

RESET button .
