Low voltage to ignition
module
- Below 15.5 VAC
Module will not proceed to trial for
ignition. When fault is corrected,
module resumes trial for ignition,
after a one minute delay.
1. Check voltage to ignition
module during trial for
ignition.
2. Check supply voltage to
machine.
6+2
Lockout
- Failed 90 second
trial for ignition
Remains in lockout until power is
cycled.
If pilot burner fails to light on
next trial for ignition - check:
1. Gas supply.
2. Pilot burner.
3. Spark/flame sense wiring.
4. Flame sense electrode
contaminated or out of
position.
5. Pilot burner ground.
6+3
Lockout
- More than 5 pilot
flame failures while
main burner was on
during the same
Call for Heat.
Remains in lockout until power is
cycled.
If pilot burner fails to light on
next trial for ignition - check:
1. Gas supply.
2. Pilot burner.
3. Spark/flame sense wiring.
4. Flame sense electrode
contaminated or out of
position.
5. Pilot burner ground.
6+4
Flame sensed out of
sequence
- longer than 10
seconds
When pilot flame is no longer
sensed (pilot out), the ignition
module enters soft lockout. Flash
code continues. Module auto resets
from soft lockout after one hour and
restarts trail for ignition.
1. Check pilot burner.
A.
If pilot flame present,
replace gas valve. If
no pilot flame, cycle
Call for Heat, or
power.
B.
If error repeats
(continual or
intermittent), replace
ignition module.
ON
Soft lockout due to
error during self check
Ignition module auto resets from soft
lockout after one hour and restarts
trail for ignition.
1. Cycle Call for Heat, or
power to reset. If error
repeats, replace ignition
module.
