Troubleshooting Instructions
READ THIS ENTIRE SECTION BEFORE
BEGINNING TO TROUBLESHOOT PROBLEMS.
The following troubleshooting gude provides systematic
procedures for isolating equipment problems. This guide is
intended for use by a QUALIFIED GAS HEATER SERVICE
PERSON. DO NOT ATTEMPT TO SERVICE THESE BROOD
HEATERS UNLESS YOU HAVE BEEN PROPERLY TRAINED.
TEST EQUIPMENT REQUIRED
The following pieces of test equipment will be required to
troubleshoot this system with minimal time and effort.
• Digital Multimeter
- for measuring voltage and
resistance.
• Low Pressure Gauge
- (L.B. White Part No. 00764) for
checking inlet and manifold pressures of the gas control
valve against dataplate rating.
INITIAL PREPARATION
■
Visually inspect brood heater for apparent damage.
■
Check all wiring for loose connections and worn
insulation.
Refer to the system operation sequence in this section to
gain an understanding as to how the brood heater operates.
Understanding the operation sequence of the ignition
module and related components is essential as it will relate
directly to problem solving provided by the flow charts.
The ignition control module is self-diagnostic. The red light
on the module will flash a specific pattern depending upon
the problem which is diagnosed. To effectively use the flow
charts, you must first identify what the problem is by the
flashing pattern of the L.E.D. (light emitting diode)
diagnostic light. If the light is flashing, the flash pattern will
be followed by a pause and then a repeat of the flash
pattern until the problem is corrected.

WARNING
Electrical Shock and Burn Hazard
■
Do not attempt to service or repair this brood heater
unless you are a properly trained and qualified gas
heater service person.
■
Troubleshooting this system may require operating the
unit with line voltage present and gas on. Use extreme
caution when working on the brood heater.
■
Failure to follow this warning may result in property
damage, personal injury or death.
