Remedy
Check fuse or circuit breaker. Reset or replace, as necessary.
Check electrodes for carbon buildup and clean if necessary.
Check for proper adjustment. Readjust if necessary. Check for
cracks in porcelain. If found, replace.
Check voltage between transformer leads at terminal block to
be sure transformer is being powered.
Check voltage between ignition terminal and neutral. Check
must be made before control locks out on safety. If no power,
replace control.
Use a volt meter in series with the air switch to check to see if
the switch is making (closing). Also check the adjustment of
the air switch setting. If both above do not work, check the
range of the air switch and measure the burner fan pressure at
the air pressure switch sensing port to make sure the air switch
is within range.
Check for gas pressure and for intermittent supply problems.
See Table 3 for appropriate gas pressures required at the head
of the train.
Check connections to all components.
Check fuse or circuit breaker. Reset or replace, as necessary.
Check for gas pressure and for intermittent supply problems.
See Table 3 for appropriate gas pressures required at the head
of the train.
Check electrodes for carbon buildup and clean if necessary.
Check for proper adjustment.
Readjust if necessary. Check for cracks in porcelain; if found,
replace.
Check for debris on flame scanner and clean as needed.
Check for proper location of detector.
Check voltage at terminal leading to main gas valve. If no
power, replace the control.
Tighten wiring connections.
Adjust to proper setting.
