For Heater Repair Tech Only

Limp Mode Operation The heater still operates with this error present, though the operation may not give the maximum or best performance. The unit will automatically operate at full fan speed. In FAN_LIMP the heater reverts to timing the ON and OFF fan operation with the fan speed at maximum. The fan ON time = 45 seconds from when the gas valve is energised at the start of the heating cycle. The fan OFF time = 60 seconds from when the gas valve closes at the end of the heating cycle. The fan will not vary speed, as the NG-2 has no fan RPM signal. Service Check List: • Perform Fan Speed Sensor Test − Check the speed sensor is correctly located in the hub of the motor end plate. − Check that the speed sensor loom plug is correctly fitted on the NG-2 terminal marked “TACHO”. − Check the loom and the connection plug are not damaged. − Remove speed sensor from motor end plate and check; − That no foreign matter has entered the sensor cap. − The sensor PCB is firmly secured within the sensor cap. − The 2 sensor probes on the PCB are vertically aligned. − The wiring circuit is not damaged. • Check for a loose fan impellor on the motor shaft. • Replace fan speed sensor • Check and or replace the NG-2 module and retest. • If all this fails replace NG-2 module and retest.
