Troubleshooting Guide
READ THIS ENTIRE SECTION BEFORE
BEGINNING TO TROUBLESHOOT PROBLEMS.
The troubleshooting flow charts on the following
pages provide systematic procedures for isolat -
ing equipment problems. The charts are intended
for use by a QUALIFIED GAS BROOD HEATER
SERVICE PERSON. DO NOT 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 AC and DC volt -
age and resistance.
• Microamp Diagnostic Kit - (Part No. 08507) When
used with a standard digital multimeter, this kit
allows testing of the flame sensor on direct ignition
systems.
• Low Pressure Gauge - (00764) for checking inlet
and outlet pressures of the gas control valve
against dataplate rating.
INITIAL PREPARATION
■ Visually inspect equipment for apparent damage.
■ Check all wiring for loose connections and worn
insulation.
Refer to the system operation sequence in this sec -
tion to gain an understanding as to how the equip -
ment operates during a call for heat. Understanding
the operation sequence of the ignition module and
related components is essential as it will relate di -
rectly to problem solving provided by the flow charts.
WARNING
Electrical Shock and Burn Hazard
■ Troubleshooting this system may require
operating the unit with line voltage present and
gas on. Use extreme caution when working on
the heater.
■ Failure to follow this warning may result in
property damage, personal injury or death.
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. Refer to the tables
below to identify what page to refer to when troubleshoot -
ing any problems.
Problems Page
L.E.D. Diagnostic light not on during a call for heat ..... 24
L.E.D. diagnostic light flashing:
A. Rapid Flash ............................................................. 25
B. Long Flash (2 seconds on - 2 seconds off) ............. 25
C. One Time ................................................................ 25

Components should be replaced only after each step has
been completed and replacement is suggested in the flow
chart.
