Operator Troubleshooting Procedures MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Step 2.  Is the battery fully charged? Charge battery using battery charging adapter IAW WP 0006 00. 6. Fault Code 2 – Locked Rotor, Combustion Blower Assembly (motor does not run) Step 1. Is the fan rotor on the combustion air blower assembly locked by ice or snow?   This fault condition is caused by a locked fan rotor within the combustion air blower assembly. It is possible for snow or ice to be ingested in the fan. The snow or ice melts and then refreezes, locking the rotor. If this problem should occur, notify unit maintenance and schedule the removal of the combustion air blower assembly to unlock the rotor. If rotor is not locked due to snow or ice ingestion, notify unit maintenance and schedule the replacement of the combustion air blower assembly. 7.

Refer to WP 0001 00, Table 3. Approved Fuels At Various Temperatures. Verify that fuel being used is appropriate for the temperature in which the heater is operating. Step 2.  Has manual reset thermostat been tripped? Remove any obstructions from heater inlet and outlet to allow free air movement. Reset manual reset thermostat. Step 3.  Is there a kink or loop in the fuel hose restricting the flow of fuel to the heater? Remove any kinks or loops in the fuel hose and make sure that it lies flat along ground. Ensure that there are no kinks in the hose on the gravity feed adapter. Ensure that all fuel quick disconnect connectors are securely engaged.
