1. There is no response after startup. Solution: measure whether the heater power supply is normal according to the circuit diagram, check the vehicle fuse and line power supply, check the power supply, check the startup signal line, and check the ground wire.
2. If the indicator light is always on or flashing, the solution is to determine the fault position according to the flashing frequency of the heater indicator light and the fault flash code table, and repair or replace the corresponding parts.
3. The heater emits black smoke, and the solution is: carbon deposits on the heater, clean up the carbon deposits, fuel injection nozzles or filters or oil pipes are blocked, clean or replace the corresponding parts, reduce the oil pump pressure, adjust the oil return pressure, and replace the oil pump if necessary.
4. The heater works normally, but repeatedly extinguishes the fire. Solution: when the hot spot couple is heated, the internal furnace wire will be connected to the shell, resulting in a short circuit of the ignition sensor. The controller considers that the fire is extinguished and needs to replace the ignition sensor.
