Causes of Frequent Shutdowns for Mobile Trailer Diesel Generators

The mobile trailer diesel generator is an individual power unit, and it can be moved and deployed in the places where need power supply. Unlike fixed generators that are usually hardwired to a building's electrical system, our mobile trailer diesel generators can provide you flexibility and mobility.

If you need power during outdoor activities, field operations or unexpected power outages, you will appreciate the reliability of mobile trailer diesel generators. However, if the generator shuts down frequently, it will become a troublesome issue for stable power supply.

In this study, we will explain the common causes of frequent shutdowns of mobile trailer generators and explore practical solutions to ensure stable power supply when needed. In addition, these generators are available in various sizes, ranging from compact models for field operations to large units that support basic electrical equipment during prolonged power outages.

The generator plays a vital role in providing backup power. However, accidental shutdowns are a common issue. The main causes of accidental generator shutdowns are as follows:

Overload: connecting too many electrical devices or equipment may exceed the generator’s capacity and cause automatic shutdowns.

Low fuel level: generators with safe performance can prevent engine damage caused by insufficient lubrication, avoiding subsequent automatic shutdowns.

Air filter is dirty: a clogged air filter will restrict airflow, leading to overheating and protective automatic shutdowns.

Fuel questions: expired fuel, carburetor malfunction or insufficient fuel supply can disrupt the fuel-air mixture and cause automatic shutdowns.

Spark plug malfunction: wear or dirty spark plug may cause ignition malfunction and intermittent shutdowns.

AVR malfunction: the AVR malfunction may lead to unstable power output and trigger a shutdown.

Engine overheating: insufficient ventilation or excessive ambient temperature will cause engine overheating and automatic shutdown.

Defective ignition system: defective ignition units may disrupt startup, normal operation and lead to shutdowns. 

Outdated firmware or software: lack of software updates may lead to malfunction and operating problems, and the generator accidentally shuts down.

Machine ware: aged components or worn parts may lead to the frequent shutdown and accidental shutdown.

Know more about these potential problems can help users regularly maintaining and troubleshooting faults, that will ensure the stable operation of generators. 

If your diesel generator suffers frequent accidental shutdowns, please troubleshoot and follow the steps below:

Check the oil level: you should ensure your generator has sufficient oil supply. Low oil level may trigger automatic shutdown.

Check the air filter: clogged air will limit the air flow, that may lead to overheat and shutdown. Regular clean or replace the air filter is crucially important.

Check the fuel filter: dirty or clogged air filter will prevent the fuel flow and shutdown. According to your need to replace the fuel filter.

Check the spark plug: wear or dirty spark plug may disrupt ignition to cause intermittent shutdown. So, please regularly check or replace the spark plug.

Fuel quality evaluation: stale or contaminated fuel will impact the performance of generators. Therefore, it is important to use flesh and clean fuel to achieve the optimal operation.

Overload management: overloading the generator will lead to automatic shutdown. Firstly, reasonably configure electrical equipment to reduce and avoid excessive load.

Check whether the connections are loose: the electrical connection is loose may lead to power interruption. So, regularly check and tighten all electrical connections.

Clean the carb: a clogged carburetor will disrupt the fuel-air mixture. Please clean it regularly to ensure the generator operates properly.

Check the automatic shutdown system: some generators are equipped with an automatic shutdown system that activates due to various faults. Investigate and resolve any faults in this system.
