TROUBLESHOOTING T able 17 — LED Error Code Service Analysis PROBLEM CAUSE REMEDY Hardware failure. (LED OFF) Loss of power to control module (IGC). Check 5-amp fuse on IGC, power to unit, 24-v circuit breaker , and transformer . Units without a 24-v circuit breaker have an internal overload in the 24-v trans- former .
T able 18 — Durablade Economizer T roubleshooting PROBLEM CAUSE REMEDY Damper does not open. Indoor (evaporator) fan is off. 1. Check to ensure that 24 vac is present at terminal C1 on the IFC or that 24 vac is present at the IFO terminal. Check whether 24 vac is present at PL6-1 (red wire) and/or PL6-3 (black wire).
T able 19 — P ARABLADE Economizer Service T roubleshooting PROBLEM CAUSE REMEDY Damper does not open. Evaporator fan not on. Check wiring between G on connection board and indoor (evaporator) fan contactor . No power to economizer motor . 1. Disconnect power at TR and TR1.
T able 20 — Cooling Service T roubleshooting PROBLEM CAUSE REMEDY Compressor and condenser fan will not start. Power failure. Call power company . Fuse blown or circuit breaker tripped. Replace fuse or reset circuit breaker . Defective thermostat, contactor , transformer , or control relay .
T able 21 — Heating Service T roubleshooting PROBLEM CAUSE REMEDY Burners will not ignite. Misaligned spark electrodes. Check flame ignition and sensor electrode positioning. Adjust as needed. No gas at main burners. Check gas line for air purge as necessary .
