I got a call from a friend tonight. He said he came home to a cold house and his carrier furnace baord was flashing 1 long and 3 short (or maybe 3 shorts and 1 long) He turned off the power and turned back on, and then it ignited and run normal until the stat was satisfied. He says there is nothing on or inside the cover telling what the code means.

TROUBLESHOOTING
It should be noted that there is no substitute for a thorough knowledge of the equipment and related systems.
It should be recognized that the majority of the problems arising in the machine will be centered in the hydraulic and
electrical systems.
electrical systems.
The first rule for troubleshooting any circuit that is hydraulically operated and electrically controlled is to determine if
the circuit is lacking hydraulic oil and electrical control power. This can be ascertained by overriding the bypass valve
(mechanically or electrically) so that oil is available to the function valve, then overriding the function valve mechani-
cally. If the function performs satisfactorily, the problem exists with the control circuit.

NOTE: It may also be helpful to do the following for intermittent or difficult problems: run a system test, ANALYZER -> SYSTEM
TEST; check the machine personalities, ANALYZER ->PERSONALITIES (refer to Table 5-3, Machine Model Adjustment
(Machines with Sevcon - 1600346 Power Module Only)); and check the machine setup, ANALYZER -> MACHINE SETUP
(refer to Table 5-5, Machine Configuration Programming Information (Machines with Sevcon - 1600346 Power Module
Only)).

Correct me if I am wrong but the APX Series on digital trunking will only Decode the Digital QCII? I have the APX8000xe! Or will it by chance Encode Also? I been trying to figure it out, I have went in and setup my tones and when I go to assign the QCII to the Menu it will not come up after writing back to the radio. The Option was specifically ordered when the radio was purchased. If it will encode can someone assist me with the setup please?
