Self Diagnostic Electronic Control Module
Certain furnace models are equipped with a self-diagnostic
electronic control module. If a furnace component is not op-
erating properly, the control module will repeatedly flash a
red light on and off in a factory-programmed sequence, de-
pending on the problem encountered.
If a furnace equipped with a self diagnostic module is not
operating properly, look through the observation window in
the blower access door and make note of the number of
flashes in the sequence. Contact a qualified servicer for fur-
ther information. Do not attempt to troubleshoot the prob-
lem yourself.
