On a ComfortBridge™ furnace using the shared data
memory chip is a “last resort.” The CoolCloudHVAC™ App
should be used to populate shared data to the control via
the “Shared Data” menu under Furnace tab.
A ame sensing device is used in conjunction with the
ignition control module to prove combustion. If proof of
ame is not present the control will de-energize the gas
valve and “retry” for ignition or lockout.
WARNING
1. Disconnect the ame sensor wire from the sensor.
2. Connect a micro-amp meter in series with this wire and
the sensor terminal.
3. Be sure the positive side of the meter is to the ame
sensor wire and the negative side of the meter is to
sensor terminal.
WARNING
4. Place the unit into a heating cycle.
5. As soon as ame is established a micro-amp reading
should be evident once proof of flame (micro-amp
reading) is established, the hot surface ignitor will be
de-energized.
6. The Integrated Ignition controls will have 1 to 4 micro-
amps. If the micro-amp reading is less than the minimum
specied, check for high resistance wiring connections,
sensor to burner gap, dirty flame sensor, or poor
grounding.
7. If absolutely no reading, check for continuity on all
components and if good - replace ignition control module.
