1. The Honeywell "Flame Sense Measurement Kit", Amana
®
brand part # R9900026, is required to correctly measure
the microamp flame proving current.
2. Connect the Honeywell "Flame Sense Measurement Kit",
Amana

brand part # R9900026, as instructed in the kit
instructions.

3. Place the unit into a heating cycle.
4. As soon as flame is established a microamp reading
should be evident once proof of flame (microamp reading)
is established, the hot surface ignitor will be de-energized.
5. The minimum microamp reading is 0.12 microamps for
SV9500 valves and 1.40 microamps for SV9501 valves. If
the microamp reading is less than the minimum speci-
fied, check for high resistance wiring connections, the
distance between the sensor and burner, flame sensor
connections or poor grounding.
6. If no reading, check for continuity on all components and
if good - replace ignition control module.
NOTE:
Contaminated fuel or combustion air can create a
nearly invisible coating on the flame sensor. This coating
works as an insulator causing a loss in the flame sense sig-
nal. If this situation occurs the flame sensor must be cleaned
with emery cloth or steel wool. Do not use sand paper, the
silicone in sand paper will further contaminate the sensor.

1. Disconnect the flame sensor wire from terminal FS of the
ignition control module.
2. Connect a microamp meter in series with this wire and
terminal FS.
3. Be sure the negative side of the meter is to the wire and
the positive of the meter is to terminal FS.

4. Place the unit into a heating cycle.
5. As soon as flame is established a microamp reading
should be evident once proof of flame (microamp reading)
is established, the hot surface ignitor will be de-energized.
6. The nominal microamp reading is 4 microamps.
7. If the microamp current is less than 1 microamp, the igni-
tion control will flash a code of 7 flashes. If the microamp
current is less than 0.4 microamps, the control will lock-
out and flash a code of 1 flash after attempting to re-
establish flame sense.
8. If the microamp reading is less than the minimum speci-
fied, check for high resistance wiring connections, the
distance (3/16") between the sensor and burner, flame
sensor connections or poor grounding.
9. If no reading, check for continuity on all components and
if good - replace ignition control module.
