This is only intended as a guide and should not be used blindly. Your experience and expertise are of high value when troubleshooting this unit. Do not disregard all of your instincts. The microprocessor furnace control was designed with diagnostic capabilities built in. LEDs are used to flash a fault code which will lead you to 1 of the subsections as listed in the Index. You should ALWAYS begin in the START HERE subsection (see Index for page number) which will guide you to the appropriate subsection where a minimal number of steps will be used to correct the problem. If you are very experienced at how this furnace operates and you suspect the problem is either the blower motor, inducer motor, or furnace control board, you can use the quick motor test procedure at the end of the troubleshooting guide to isolate the problem or direct you to appropriate section in main troubleshooting guide. Once in a subsection, read the statement or question. A statement will have a number in the “GO TO ” column. Do whatever the statement says, then proceed to step indicated in the “GO TO ” column. If the step is a question (a question will have a number in the “YES ” or “NO ” column), answer it “YES ” or “NO. ” If the answer is “YES, ” go to step indicated in “YES ” column. If the answer is “NO, ” go to step indicated in “NO ” column. Let’s try our guide out using the EXAMPLE section below, and see how it works. Suppose that the problem is a defective low-pressure switch (for example will not make). This is an internal problem and cannot simply be seen. We go to the START HERE section to Step 1. Additional Service Tools are available for current variable speed condensing furnaces. The Advanced Product Monitor Kit KGAFP0101APM includes a harness and diskette that allows communication with the control board through a personal computer (RS-485 adapter required). The ICM Motor Simulator Kit KGASD0101FMS is a plug-in device to help trooubleshoot ICM inducer and blower motors and control boards. Reference price pages for current kit numbers. SEQUENCE OF OPERATION Furnace control must be grounded for proper operation, or control will lock out. Control is grounded through green wire routed to gas valve and burner box screw. Using schematic diagram (see Appendix A), follow sequence of operation through different modes.
